Review of Anker 40W 5-port USB wall charger w/lots of pics!!!

This is a review of Anker 40W 5-port USB wall charger. http://www.ianker.com/product/71AN7105-BA
Anker guys never cease to amaze me. Just when I think I know what to expect, here comes another surprise. I just received their new 5-port usb wall charger, and was thinking to myself it's probably the same as my previously reviewed 25W 5-port charger, just 3A of additional current. But was I in for a big and pleasant surprise! That original 25W 5-port charger became my irreplaceable everyday accessory with access to charge 5 separate usb devices from a single compact charger plugged to one wall outlet. The new 40W is a big step up, and here is why.
Typical for all the latest Anker products arriving in eco-friendly packaging, the box is also made out of recycled carton with a zero hint of plastic. Upon opening it up, you are presented with a small usb charger and a 5ft detachable cable. When I say small charger, I really mean the size of most common single usb output 1A chargers. With a dimensions of 3.6" x 2.3" x 1" and weight of only 4.6oz this charger is even smaller and more compact than original 25W charger, something I didn't expect considering this new charger is 40W (8A) rated versus 25W (5A). Don't get me wrong, the original 25W charger is still a fantastic product, but they just made it obsolete by releasing a higher capacity the same 5-port charger in a more compact package. Furthermore, the exterior is now wrapped in a soft touch material, similar to their 2nd gen Astro external batteries. It's less slippery, less prone to fingerprints, and feels a lot more rugged especially when you take it with you on a trip.
Upon further examination, the next big change is ALL 5 ports being universal without any apple/android/ipad/samsung labeling. The original 25W version was partitioned with ports for specific devices. Sure it was a good idea, but it required constant close up reading when plugging my other than Samsung (Note 2 is universal with any output) gadgets. What does this mean? Every port is universal with a smart feature and its own microchip to determine max charging speed of the connected device to adjust current supply accordingly, even for the latest iPad with 2.4A. Basically you can have 5 separate devices plugged in and each one will have a tailored current supply adjustment for a total that can't exceed 8A. So unless you are planning to plug in 5 latest iPads, you are in a pretty good shape with more than enough of current supply. For my test, I actually had my Note 2 plugged in by itself to confirm average charging of 1.7A, and then plugged in 3x Nexus 7 tablets (two 2012 and one 2013 edition), and the current draw on my Note 2 stayed the same while Nexus tablets were charging at their corresponding 1A/1.5A speed.
Overall, at the current moment you will not find anything even remotely as advanced as this new 40W 5-port USB wall charger which can power up 5 separate gadgets (a mix of Android, Apple, and any smartwatch, headphones, mp3 player, etc.) and provide a combined 8A of regulated and smart adjusted supply for all it's ports. With such a compact package, 18-months warranty, and for only $25 plus change - I consider this as a MUST HAVE accessory for anybody. Period.
Here are the pictures (the white one is the original 25W charger, for comparison).

I updated the link in the review with the one directly from Anker. I have been told those were sold out in the first few days and now they are waiting to get more in stock. So better use direct Anker link since out-of-stock amazon link doesn't show up.

Was finally able to grab one this morning on Amazon. Definitely a hot seller!

I don't label a lot of accessories as "must have", but this one definitely deserves that

This thing works great! Successfully charged an HTC One, a Moto X, a Razr M, an iPad 3, and a Nexus 7 (2013) simultaneously at full speed. Thumbs up! ?

Cool! Definitely a must have!
I had current issues before...I found out it was the cable. I know it could be obvious but most of us think "hey, this cable looks good, should work good too"
By the way. I think Kingston's Data Traveler microDuo 3.0 is a must have too. Sorry, i can't post link yet.

Review of UNU SuperPak 10,000 mAh ext battery with SuperX input w/lots of pics!!!

This is a review of UNU SuperPak 10,000 mAh external battery. http://www.myunu.com/unu-superpak-battery-pack-for-smartphones-and-tablets.html , also available on Amazon: http://www.amazon.com/UNU-Superpak-10000mAh-Lightning-compatible/dp/B00LXL6L9E/
External battery market is saturated, and it’s very sad to see hundreds of different models where the only innovation is a different color casing or shape of buttons or some other cosmetic changes trying to differentiate themselves from the rest. Luckily there are still a few companies that trying to innovate in this sector of electronic gadgets, and I found UNU to be one of them. Their UltraPak Go and Tour, reviewed not too long ago, demonstrated a new fast charging technology and a built in digital display to monitor battery status. Today I’m going to look into their latest SuperPak battery which has some unique features while keeping it at a budget friendly price.
Arrived in a small packaging box, you get a nice cover graphics with a picture of SuperPak and a detailed listing of features on the back and the sides. Out of the box you will find the battery packed inside of a plastic storage tray with user manual and USB charging cable. Typically I don’t spend too much time in further description of the cable since everybody includes a typical usb to micro-usb cable with their products. Well, this is not your typical cable because in addition to micro-usb connector it has a removable adapter (attached by a cable string so it doesn’t get lost) with Apple Lightning connector for use with iPhone 5/6. Though I personally don’t have any Apple products, I think it’s a fantastic idea to provide a universal cable to accommodate charging of any device. Obviously, the same cable could be used to charge battery itself.
Now about the battery, it has a sturdy quality build and a durable metal case. The footprint of the battery was relatively small for its 10,000 mAh capacity, but also a little bit thicker in comparison to other batteries. Either way, it should be pocket friendly and easy to carry with you in the bag on the go. The design itself is very simple. The top of the battery has a typical 4 led indicator with 25% charging/capacity increments. Nothing special here except in comparison to led display of UltraPak this was one of the “corners” UNU had to cut in order to reduce the price of the unit. The rest of the ports and controls are clustered and clearly labeled on the side of the battery. In there you have a large round power button, can’t miss that, which you have to push in order to start charging. In comparison to most of the other batteries charging usually starts automatically as soon as you connect the cable, while here UNU gives you a control – just have to remember to push that button.
You also have 2 full size usb charging ports labeled uSmart 5V/2.1A and 5V/1A. They use a new charge sensing technology to supply charging current at the max speed of the connected device. UNU is not the first one to introduce this technology, but still it’s a great feature which I only found available with two other manufacturers. Also, in my test I found my Note 4 charging at exactly the same speed from either of the ports. So I’m just going to consider this as a dual output 5V power supply with a total capacity of 3.1A shared current which gets distributed and optimized according to the max charging speed of your device.
Of course, I saved the best for last – SuperX micro-usb input port to charge the UNU battery. While only a few companies focus on faster charging of the devices connected to the battery, nobody focuses on fast charging of the battery itself. UltraPak introduced super fast charging but at an expense of a bulky AC wall proprietary charger which is not very convenient when you are traveling. SuperPak uses a regular standard micro-usb input charging port which is capable of 2.4A charging speed!!! For a comparison, all the currently available external batteries have a charging input of 1A or lower. With increasing capacity of batteries, that’s roughly speaking 1 hour of charge per each 1000 mAh of capacity. So a typical 10,000 mAh battery will take about 10 hours to charge, while SuperPak with its 2.4A input will fully charge its battery in under 5 hours. You also have to keep in mind, that you will not have the actual 10k mAh of available capacity to charge your phone since conversion of internal SuperPack battery of 3.7V to 5V and back to your phone’s 3.7V battery will result in about 20% of efficiency losses.
Overall, I found SuperPak to be a great battery with a decent build, high capacity, flexibility of micro-usb and apple lightning connector, smart device charging outputs, and a unique feature of super fast 2.4A input recharging. Only a few currently available ext batteries offer smart charging outputs, and universal micro-usb / lightning connector high quality cable is definitely a bonus. But SuperX input charging feature of SuperPak is the first one I have seen. This means that you no longer have to wait to charge your ext battery overnight or keep it on the charger half of the day to get those 4 leds lit up. In half of the time you can have your SuperPak battery full and ready to go!
Here are the pictures.

Review of Xiaomi Mi 20,000 mAh dual output external battery w/lots of pics!!!

This is a Review of Xiaomi Mi 20000 mAh dual external battery.
After a few of my recent external batteries reviews I was asked if/when am I going to review the latest offering from Xiaomi, and in general how come I haven't reviewed any of the Mi batteries in the past. It wasn't a matter of not being able to obtain a review sample, but rather a problem with making sure it's a real product from a trusted source. Xiaomi established themselves as one of the top choices in budget-priced gear, and due to their popularity the market is now flooded with knockoffs which sometime hard to tell apart (Xiaomi Pistons is a good example of that). Luckily, <mod snip> is among a few trusted on-line retailers that work directly with Xiaomi distributors, selling their original licensed products. Please keep that in mind, it's not just about the product but also where you buy it to guarantee you're getting a genuine smartphone accessory. And with that "public announcement" out of the way, let's proceed to the review.
Unboxing & Accessories.
The product arrived in a small plain white box, no fancy graphics, no colorful images, just a plain "Mi" and a spec on a side in Chinese. One thing to note, there was an authenticity sticker on the side, what looks like a genuine Xiaomi label. I have enough experience to know these stickers could be duplicated, but in this case it was a real deal because I trust the source I got it from. With minimalistic box you also get a single accessory, a flat usb to micro-usb cable - high quality and very durable, all in white. The whole theme of a plain white box, a simple white battery enclosure, and a simple white usb cable can remind you of "Apple" products - clean and simple.
One missing accessory is usb to usb-c cable. I didn't even know about it until I read on <mod snip>: Mi 20k mAh battery can recharge a new MacBook with usb type-c cable, which makes sense considering it supports 5V 3.6A output. Not sure why they are not advertising it directly because it's a big marketing point for this battery, supporting USB-C technology which has been implemented in the latest MacBook, Google Chromebook Pixel, and Nexus 6P smartphone.

Design.
This minimalistic packaging also caries over to minimalistic plain white design with just a simple "Mi" stamped on the top. Even the label on the back edge is printed in light gray on white which makes it hard to read, and still has a very minimalistic discrete look. But when you take a closer look, you realize there is more to it. To keep the weight down, amazingly enough for 20k mAh battery which is only 338g, Xiaomi used a durable yet environmentally safe combination of PC+ABS plastic with a very fine bumps that make surface anti-skid and anti-scratch. Also, considering such a huge capacity, the dimensions are only 142mm x 73mm x 22 mm, making it among the smallest and the lightest batteries in 20k+ category.
Looking at the top side edge of the battery you will find a single power button which turns on 4-led power indicator to let you know about the remaining storage capacity. I didn't have to press power button to start charging my phone. On the front edge, you will find 2 full size usb Output ports, one micro-usb Input charging port, and 4-leds indicating the remaining capacity or the charging capacity (when re-charging the battery). This 4-led indicator was really a step back for me considering you get only 25% incremental granularity, while I got spoiled by Anker and their 10-led segment indicators. Not really sure why Xiaomi decided to have such a simplistic power indicator, though I'm guessing they probably wanted to keep it small without taking too much room.
Specification and operation.
Obviously this battery wasn't marketed for worldwide release because instructions are all in Chinese, and this is why I do appreciate that Gearbest put as much info as possible in English on their website: Mod Edit by @Darth : Link to online store removed. . Reading specification and looking through some of the marketing pictures REALLY clears up what's under the hood of this battery.
First of all is a charging micro-usb input to recharge the battery itself. 20,000 mAh is a huge capacity, so forget about using any of your outdated 1A or 1.5A wall chargers. <mod snip> mentions "Support DC 5V / 2A, 9V / 2A, 12V / 1.5A quick recharging" - which is a dead giveaway of QC2.0. Of course, it also supports a regular fast 5V @ 2A charging, but it's nice to have both options. Either way, it will take about 7-8 hours to fully recharge the battery, which is not bad for such high capacity.
In my test, I found with a regular 2A charger I got: 5.33V @ 2.01A
And using Samsung Fast Charger: 6.62V @ 1.63A
When it comes to the charging output of dual USB ports, those support 5.1V with max 3.6A output. That translates into up to 2A for a typical smartphone charging and 3A for USB-C charging. I can't test/verify USB-C since I don't have any devices supporting it yet, but it's a great feature to have in order to future-proof your charger. With usb charging, I was able to confirm it with my Note 4 and it's on par with all of my other 2A chargers, and btw 2A is "max" so the actual charging speed is usually less, where in case of my phone it was about 4.96V @ 1.71A
Another thing to keep in mind is close to 90% efficiency of conversion, considering going from internal battery of Mi to 5V USB port and then through usb cable to your phone and back from 5V micro-usb to internal battery (all this involving a typical 3.7V to 5V conversion with some loses due to efficiency). So realistically you are looking at close to 18k mAh of usable capacity.
Conclusion.
Doesn't take a rocket scientist to realize that I was impressed with this battery Due to a lack of access to USB-C devices, I can't test it to its full potential, but I still found it to be among the smallest and the lightest 20,000 mAh batteries I have tested to date. Yeah, the battery is not fancy with aluminum enclosure or better led power indicator, unfortunately you will have to live with a plastic shell and 4-led indicator, but it's still a quality build with a packed functionality, high capacity, full 9S circuit protection, and the big one - priced under $35 shipped free from <mod snip>. But the most important factor is that you can have a piece of mind knowing it's a real Xiaomi product, not a knockoff.

thx man!

Sorry if I missed the question, what did you "solve" ?
Btw, I few people contacted me asking about the link where I got the battery. I think something was wrong with my original link, so it was deleted by moderators. It is still available for $35 from Gearbest, www.gearbest.com/iphone-power-bank/pp_263761.html, the best price I found so far. On ebay they go between $38-$45.

nice review!

I finally knew that to recharged Xiaomi power banks at maximum amps (2A) , we must use the original 2A chargers comes with phones.
Because if using multi-port aftermarket chargers like ANKER 60W & PowerPort 4, I can only get Max. 1.6A
Still want to hear from ANKER.

Unboxing
The Solar Charger comes with an eco-friendly packaging and basic accessories: 1x Micro-USB Cable, 1x User Manual, and the Solar Charger (of course).
Everything is fit into a synthetic material, just like the one used for bags or similar, and seems to be pretty hard to be scratched and it can be also cleaned easily. On the back there is a foldable stand that can be used to charge the device, useful especially when you can place it in a flat surface, otherwise you can just place it on the grass so that it gets maximum power from the sun.
Inside the back pouch its where all the magic happens. The solar panels and the Li-Ion battery are connected to this little hardware where the power is trasformed from 5.5V (solar charger input) to 4.2v/4.3v (depending on the battery core) in order to recharge the built-in battery, and in the same time the built-in power is then transformed to 5v for the USB Output. A little box for such complex work, and it works pretty well. Check efficiency test, written in the next paragraph.
There are 2x USB ports available, with maximum 2.4A output (i don't know if it is maximum combined output or not, but my tests seems to confirm the first option).
It is possible to charge the built-in battery together while charging your devices though the USB ports, but there is no Micro-USB port to recharge it if no sunlight is available. That's the only minor thing that disappointed me a bit.
While charging, with sunlight power, a LED placed between the USB ports turns red, it can be more bright or not depending on the sunlight power, and the battery level LEDs start to blink.
This Solar Charger is pretty compact, smaller than an A4 paper, and doesn't weights a lot too. It can be easily transported in your backpack without having to increase its weight too much. Do not forget that there are two big solar panels here, so can't expect something super lightweight.
I am not a Solar Panels expert, but the ones used in this charger seems to be good-quality ones. Check this photo, they really seem well made.
Efficiency
All tests have been done using my own Micro-USB cables, because i don't trust the provided one so much. It feels a bit cheapy, but i could be wrong.
On Idle the output voltage stays on 5.08v, matching USB specifications. Even while charging it, the voltage doesn't change at all so, as i said before, the first chipset that works on the USB Output is firstly connected to the Li-Ion Battery Controller, then to the Solar Panels.
I have tested the USB Ports using my USB Capacitor (1A/2A), and the voltage seems to get a bit low on extreme-load. With 2A load, it manages to stay stable still meeting the USB specs.
With extreme-load, more than 2A, the voltage drops to 4.65v. Well this is an extreme test, but i would certify this charger for maximum 2.2A load in order to get stable voltage. Anyway, it is still matching USB specs, even if to the minimum limit.
While charging, it doesn't get hot, but if you charge it with direct sunlight and in the same time you charge your device, then everything gets hot, but hey this is the power of the sun, no one can cool down this haha.
Conclusions
Being my first time to review a solar charger, i may not express an useful opinion, but i will try to do my best. Even if not perfect, this charger may be a life-saver for those who like to stay outdoors frequently. It is solid, provides 2x USB Ports that can be always useful even if there is no Quick Charge available, and most of all, the built-in battery pack allows you to charge your devices even if the weather is not so helpful for a nice outdoor day.
So...do I recommend it? If you match the user i have just talked about, then yes this is definitely for you. Its price may not look so affordable, but solar panels are not that cheap yet (still not expensive as many years ago though), so this is a nice choice.
Pros:
- 2x USB Ports
- Can charge its built-in battery while charging other devices
- Portable
Cons:
- No Flashlight
- No Quick Charge
- No Micro-USB port to charge its built-in battery

(Review) Archeer 3.4A Dual Wall Charger

Introduction –
We live in an age where power boards have their own integrated USB ports and where 5-port chargers from brands such as Anker and Aukey have become a household stable. But beyond these home based gadgets, nothing beats the compact convenience of a basic wall charger when traveDSC06690.JPGlling.

Archeer 3.4A – Generic 2A – Samsung QC 3.0​These wall chargers are pretty standard with a 5, maybe 10 Watt output delivering 1 to 2 amps to your smart device respectively. Though more tech orientated buyers will probably invest in a 2A dual port charger as a lot of travelers carry both a smartphone and tablet. But this is where the limitations of this charging system are reached. Most manufacturers market these chargers at 2A, but in reality that’s 2A shared over the two ports, equating to just 1A each. Since most tablets require a 2A charger, charging both a tablet and smart device simultaneously is not possible. And that’s where the Archeer charger comes in.
Disclaimer –
I would like to thank Archeer very much for providing me with a charger in exchange for my honest opinion. There is no monetary incentive for a positive review, I will try to be as objective as possible during my evaluation of the product.
Packaging –
Archeer have a pretty typical non-fills approach to packaging that works well but doesn’t flatter the buyer. The dual charger is packaged within a basic cardboard box and nestled within a protective foam inlet that snugly holds the device.
Design & Usage –
Bearing an atypical 3.4A output condensed into a relatively compact frame, the Archeer dual charger produces 50% more output current than a conventional charger. It’s not a small charger by any means but is only slightly larger than a conventional quick charge adapter whilst offering 2 outputs.
A 3.4A max output makes it powerful enough to charge both a tablet and smartphone simultaneously or simply charge one device with quick charge like speed. Here’s what the output looked like after running a few benchmarks on my Nexus 9.
I’m not sure why it’s capped at 1A, but it’s likely due to my Nexus being on 81% rather than the charger itself. I didn’t notice any abnormally slow charge times during my testing.
There’s also a little more method to the design than the average charger. With a grippy matte finish and a black colour scheme, the device looks quite classy without attracting too many fingerprints. Archeer also outfit the charger with a small blue LED to denote power along with dimpled sides that make the charger much easier to remove from tighter outlets.
The charger supports 100-240V which will cover most international outlets and outputs at 5V with 3.4A shared between both ports (both have the ability to charge at the full 3.4A if the other port is free), meaning no quick charge support for Qualcomm devices. Nexus devices should be able to draw the full 3.4A through a single port.
Archeer integrate protection circuits against over-volting, short circuit and overheating. There’s also some smart charging technology similar to that implemented by Anker and Aukey chargers that delivers precise amounts of current to your devices rather than using inbuilt presets for the fastest, safest charge possible.
Brand Archeer Dual USB Wall Charger 17W 3.4A 2 port USB Charger Adapter Home Travel USB Charger For iPhone 6s 6plus
Whilst I lack the electronic expertise to empirically confirm these claims, charging times were similar to my 60W Aukey 5 port charger. Currently the charger is available with US (pictured), UK and European plug configurations. The US model is easily modified using a set of pliers to fit Australian outlets as pictured below, omitting the need for an adapter.
Verdict –
So overall, the Archeer Dual charger is a pretty convincing device. It has a solid feel in the hand and a nice build overall. The addition of a status LED, high power output and dual USB ports make it feel all the more premium. But these impressions have yet to factor in the price, which is perhaps the most compelling aspect of the charger. The Archeer 3.4A dual charger can keep all your devices topped up for $9.99 on Amazon for US customers and just $8 AUD for international buyers on Aliexpress. That makes it about 3X cheaper than the basic 1A iPod charger sold by Apple. The Archeer dual charger is a convenient, cost effective charger that is well suited to travelers and home users alike.
