This is a review of NewTrent NT70T EasyPack 7000 mAh external battery charger: http://www.newtrent.com/store/andro...nt70t-external-battery-ipad-battery-pack.html
Here is another great product I discovered that will definitely benefit Note 2 users who are sticking with a regular size battery and their favorite case and need backup power on the go. This particular unit has a very portable footprint and it's relative slim with dimension of 119mm x 74mm x 18mm (4.7" x 2.9" x 0.7"). It's also pretty lightweight for 7000 mAh capacity, at 6.8 oz (193 g). It's definitely very comfortable and pocket/purse friendly. As a matter of fact, this unit is actually intended to be used on the go where you don't even have to worry about power cables since it has built in full usb cable for Input charging (a fast 5V, 1A port) and also micro-usb cable for one of the Output charging ports (5V, 1A). In addition to 1A output port with micro-usb cable, it also provides 2 additional usb ports with 2.1A and 1A outputs. These got you covered for any smart phone or tablet, and can also charge two devices at the same time.
For convenience if input charging cable is not long enough for you, New Trent also included USB extension chord which I found to be a great bonus. No other chords or adapters were included with this product. The device itself is very slick with a footprint reminding me a small external hard drive. The bottom of this power bank is finished matte while the top has a shiny piano finish. On the top you also have a discretely placed power button and 4 led power meter indicators with cool green lights. Those 4 lights partition power reading into 25% increments.
Beside its portability and convenience of built in cables, the main attraction of this device is a whooping 7000 mAh capacity. This is some serious number!!! And NT70T has this 7000 mAh speced at 3.7V - the voltage of the actual lithium battery. To be honest, I was a little skeptical at first because external battery market is flooded with a lot of high capacity external batteries that have exaggerated labels. So right away I put this battery to the test. I had my Note 2 discharged down to 25% while NT70T was charged all the way to full (4 leds lit up). I used 2.1A output port for a faster charging and used my own usb-to-micro-usb cable. My Note 2 battery got charged up to 100% in under 3 hours. That was very impressive. After charging it up, I checked with NT70T and it still had 3 leds on!!!! Of course, 3 leds doesn't mean it's at full 75% charge, but rather between 50% and 75% charge. But still, very impressive considering we are talking about our GN2 with 3100 mAh stock battery. As a bonus, you can actually charge your phone while charging NT70T, pretty cool although not recommended by manufacturer since it can accelerate aging of the battery.
In my opinion this is one of the top small footprint portable external battery chargers that offers simultaneous charging of two devices at the same time with one port being 2.1A and others at 1A, and having a whooping true 7000 mAh capacity!!! A must have if you need a portable backup battery and don't wont to part with your current Note 2 case (to accommodate bulky extended battery). I definitely recommend NT70T EasyPack!

Good one!!!! I gotta tell these guys to fix this typo
Btw, I have their new NT120C (http://www.newtrent.com/carbonpak.html) coming my way for review - looks cool! That one is a step up with a higher capacity at 12000 mAh, although no built-in cables to give you more flexibility. Should have it sometime next week, will post a review then.
Thats a really stylish looking external battery charger.

This is a review of Anker Astro2 (2nd generation) 9000 mAh external battery: http://www.ianker.com/product/79AN7903-BA
Just a short while ago Anker introduced their next gen Astro3 battery. Following it's footsteps now comes next gen of Astro2 with all new design details introduced in Astro3 but in scaled down version of it. Some might argue it has a reduced capacity and one less charging usb port in comparison to Astro3, while the price difference is not that significant. So why would someone choose one over the other? Let's find out.
First of all, I'm glad to see how Anker switched to all new packaging across all of their latest products, using environmentally safe recycled material and minimum amount of plastic. The battery itself uses a nice soft touch rubbery material that will not leave any fingerprints and gives you non-slippery grip. The shape of the battery has rounded off edges and is very comfortable to hold. With my measured dimensions of 105mm x 60mm x 23mm and reduced weight down to 7.7 oz (218 g) - this battery is relatively light and very pocket friendly. It comes with micro-usb input capable of 1.2A charging rate for a faster charging of the battery itself, and 2 full size usb charging ports one labeled as Smart Output with 2.4A max charging speed and another one labeled as Universal Output able to support up to 3A of charging current. Per confirmation from Astro3 which also has Smart Output with 2.4A - that port will charge your latest iPad at max speed! Universal Output will be able to support any latest smart phone with a full 2A charging speed. Both ports can be used simultaneously for a combined charge output of 3A. I have verified charging my Note 2 at 2A and Nexus 7 at approximately 1A charging speed simultaneously. In addition you also get micro-usb cable, 30-pin apple adapter, and a very nice mesh storage bag.
Just like with Astro3, this new Astro2 uses a 10-segment led indicator which breaks down charging capacity in increments of 10% instead of typical 4-led batteries with 25% increments. The led lights are not visible until you shake the battery to reveal remaining segments. While you charging battery itself, those will stay up indicating charging progress. What sets this 2nd gen battery apart from so many other external batteries available today is the efficiency. As I mention in all of my ext battery reviews, the labeled capacity is not the actual capacity because you loose energy during conversion through usb output port. Typical ext battery looses on average 30-35% thus you are getting only 2/3 of the actual capacity. The new 2nd gen of Astro3 and Astro2 have 80% efficiency, thus you are loosing only 20%. I was able to confirm that with multiple charges an average of 78% which is close to advertised 80%. It means that you should have no problem getting 7000 mAh from this battery.
Overall, in my conclusion I want to make a point about Astro2 vs Astro3. Both are fantastic batteries with innovative design and very impressive efficiency. One has higher capacity and additional usb charging port while the pricing is very close in comparison, especially with the latest Back-to-School sale on Astro3. So why would you choose Astro2 over Astro3? The deciding factors are the size/weight/portability. If you need to carry your ext battery in a pocket or a smaller purse - Astro2 will be the way to go. Just look at side-by-side pictures. That's what it really comes down to.
Here are the pictures.

This is a review of Anker dual usb port 4.8A (2x 2.4A, total 24W) car charger. http://www.ianker.com/product/71AN2452C-WA
Just a few months ago I reviewed Anker's dual usb car charger with 3.6A combined output. One of the comments I heard back was about charging Note 2 and iPad 4th gen. As you know, Note 2 needs 2A for a full charge while 4th Gen iPad needs 2.4A. Or perhaps you got Note 3 in addition to Note 2 and need to charge up both of these 2A phablets in your car. In that case 3.6A doesn't cut it. The solution: 4.8A charger with dual usb port output each being able to deliver 2.4A.
Continuing with their new environmentally safe cartoon package, this one arrived in a neat little box. In addition to car charger, it came with Instruction manual which I want to mention specifically since Anker has been updating these with more and more useful details. They might as well call it a car charging Guide. But one thing I do have to mention, even so this charger has 2 ports labeled Android and Apple - in case of Note 2 or any other newer Galaxy phones, both ports can be used to charge your phone at full speed as I captured in the pictures below using Galaxy Charging current app.
This new 4.8A charger is the same size as their previous 3.6A model. Its very compact at 31g with 2.9" in length and 1" x 0.9" at the dual usb port opening which is smaller than some of the other single output car charger. This car charger is able to accommodate simultaneous charging of 2 plugged in devices at 2.4A each for a total output of 4.8A, and according to instruction manual has built-in multiple circuit protections. With Anker's standard 18 months warranty from the date of purchase, and a current price of $11.99 - this is one fantastic value and definitely a highly recommended accessory if you want to charge multiple power hungry devices at full speed in your car.
Here are the pictures.

thank you for the review! What micro-usb cable are you using to charge the device? I'm noticing that the cable has much to do with the amperage being drawn from testing I've done with all the cables and chargers I have.
Thanks again, Vectron. Excellent review.
By the way, how did you find the accuracy of the app you were displaying to measure the current?
I bought the USB power monitor that you reviewed. I d/l the app Galaxy current (the same one you
are using) and they never matched each other. The app always show 1800 like yours when the USB
gadget wasn't installed (on a 2A charger). It showed very differently with it inline, like 1100 mA.
I wonder if you saw the same thing?

To be honest, the app and usb dongle are great for relative measurements, not the actual accurate measurement. That is a truth. When you have a dozen of different cables and chargers and trying to make sense out of it, these tools come very handy to determine which combination will give you the highest charging current. Is it accurate? The only way to check it by dealing with a known mAh capacity target and timing how long it will take to charge it from zero to full (or some starting percentage which you will have to factor into your final calculation). Once you know total charged "mAh" capacity and "h" it took to charge, you calculate by dividing mAh/h to get your mA charging current speed. On a few occasions I came very close with what I have been reading with Charging Current app. But in general, just use all this as a tool to determine best combo of your external charger/cable.
Looking Nice......
Well, I have this powerbank that is one nifty little gadget. Now, being a guy I don't mind carrying a bigger powerbank in my bag for those critical must charge situations. Whenever I'm out in the city and one of my female friends are around they sometimes need a quick phone charge during lunch. So I pull me powerbank out, connect a cable and plug in their phone. They're impressed by it but always say, "That's so cool, but it's way to big for me to carry around."
So Ravpower created this little guy. The Lipstick tube style 3000 mah powerbank w/ built in 3 mode flashlight.
Comes in a simple box with manual. Powerbank and a white usb cable. No wall charger included.

Item Weight 3 ounces
Product Dimensions 4.6 x 0.9 x 0.9 inches
Item model number RP-PB08
Size 3000mAh
Color Gold
Power Source AC & Battery
I offered it to a couple of my friends who are ladies to try it out and see how they liked it. It was an overwhelmingly useful gadget they insisted. Big enough to recharge their phones from Instagram,Facebook, Twitter, taking selfies or pics of their food but small enough to keep in their clutch or bag. Not only is it small but light in weight also.
Build Quality is excellent! Feels solid, nothing loose, no creaking or flex that I can tell.
If Gold isn't your style there are 4 colors to choose from:
Gold - 3000 mah
Silver - 3000 mah
Black - 2600 mah
Pink - 2600 mah
That being said, not all colors have the same battery capacity as the Black and Pink have small capacities of 2600 mah but the silver and gold has the bigger 3000 mah.
Pics:
The diameter is barely bigger than a nickel but smaller than a quarter.
Pic for size comparison:
Flashlight has 3 modes.
High
Low
Strobe
The flashlight is ridiculously bright and could be used to guide ships from sea if need be. A single button is used to cycle between the modes.
Press once: High beam
Press a second time: Low Beam
Press a 3rd time: Strobe
Press a 4th time: back to off.
Charging the Device is simple. All you need is a usb port or a standard wall charger with a usb port. The micro usb port is used to charge the powerbank itself. The full usb port is used to charge your device.
There is no battery indicator on how much charge is left.
When Charging a red light indicates that its not a full charge.
A blue light indicates its at full charge.
A few tests charging my nexus 5:
Starting @ 69%.
79% - 10 minutes
85% - 17 minutes
92% - 25 minutes
100% - 42 minutes
so in emergencies it does a good job for a quick mini charge till you get to a wall plug charger. It does get warm when charging your phone but it does NOT get hot.
It was able to charge:
Nexus 5
Nexus 7 2013
S3
Iphone 5
S2
Sansa Clip Zip mp3 player
So if you want a powerbank for quick emergency charges this is the Powerbank for you. It's small and lightweight. Don't expect to be able to charge your device multiple times before it runs out of juice itself.
For some of you coming from phones with removable batteries, you may have some anxiety about running out of battery life and not being able to swap a spare in. I was the same way a year ago, but I didn’t let that fear keep me from buying a newer phone without a removable battery. So I decided to just grab a few portable chargers to use and I’m glad I did.
Below is a comparison of the portable chargers I have. To try and compare them as fair as possible, the process was simple. Reboot the phone, fire up the stopwatch, set to 15 minutes, shut off the screen, plug in the charger, and leave it alone. The readings were taken from Battery Monitor Widget which was set to update the history every 60 seconds. I used a charging cable from my HTC EVO 4G LTE. I didn’t have my N5 charging cable with me and we know sometimes the cable can play a big role. So take that in to consideration if you think my numbers are off.
The portable chargers from left to right.
1.New Trent iCarrier 12000mAh Portable Dual USB Port - $39.95 (Amazon)
*The one I have is an older model which doesn’t included the “Recharge by USB” option. Mine can only be recharged via AC Wall Adapter. The new model has both options but doesn’t included the wall chargers.

Review for Each:
New Trent:
I originally bought this to be used with my Nexus 7 (2012) since it was REALLY picky about what could charge it. You can tell this is a lot bulkier than the other two and isn’t something you’ll throw in your pocket. I keep this in my backpack and only use it when I don’t plan on moving around. Or if there are two people/devices that need to be charged. The plastic housing feels a little cheap, but I understand the idea was to keep the weight down on an already ‘heavier’ portable charger. It has held up well.
I’ve used this thing 3-4 times on my phones without it dying which is nice. This one re-charges using a AC Wall Charger (No longer included) or via USB (5v 2A…no charger included). NOTE: I have the older model which does not have the “Charge via USB” option. Only the AC wall charger option which it did come with. I can’t imagine how long it would take to charge via USB. It already takes a long time using the AC Wall Adapter.
Anker Astro:
This has been my Go-To portable charger for over a year. And it still charges my phone at least twice. When it comes to size vs. capability it is the clear winner. It also includes a LED Flashlight built in. There is a 4 light meter that tells you the status of the battery when charging a device or when being charged itself. Or you can just hit the button to see how full it is.
It can easily fit in your pocket or purse. I have a few very short micro-usb cables laying around so I’ll bring that with me too so I don’t have a 3ft cable in my pocket.
Anker Astro Mini:
I just bought this on sale and was surprised at it’s weight when it arrived. It has a metal casing so that probably adds to the weight. The fit/finish is very nice looking. When holding this in one hand and the Anker Astro in the other, you don’t feel much of a difference. Yes the Mini is round/smaller, but it isn’t a huge difference for me. The mini fits in your pocket nice.
If you are looking for something very portable, a little cheaper than the other options, and a charger that will charge you up once (maybe 1.5 times), then this is a good option. But if you may think you’ll need the portable charger for more than 1 charge while out, go with the Anker Astro (5600 mAh).
I have the Anker astro, but it takes AGES to charge my n5, almost as if it was being detected as a pc usb port rather than a charger.. any ideas? Stock rooted...

What cable are you using with it?
Get the battery monitor widget app and see what it says when plugged in.
Nice quick review.
Strange that New Trent 2A output is less powerful then regular usb..
And the average charging mA for Astro mini seems bit lower than it should be. Both Astros have the same output rating, arent they?

This is a Review of UNU Ultrapack GO and TOUR external portable batteries with Ultra-X fast-charging technology. http://www.myunu.com/products/ultrapak-fast-charging-batteries.html
Some of you may noticed that I'm no longer reviewing as many different external batteries. Unfortunately, there has been very little innovation in this sector of smartphone accessories. One of the new trends I have seen so far is the increase in external battery capacity to keep up with new power hungry big screen phones and tablets. As you increase the capacity you also increase the charging time for the battery itself where in some cases even overnight charging is not enough to get to 100% ready. Realizing this shortfall, UNU engineers decided to come up with a new line of Ultra-X fast charging batteries which I got a chance to review. Here is what I found.
Since both of these batteries have a very similar design and functionality with the only difference of capacity and a number of charging ports, I decided to combine review of GO (3,000 mAh) and TOUR (10,000 mAh) Ultrapack batteries together. Both arrived in a very similar packages, only scaled in size, with a clear message of 8x Faster charging rate. The package also has a lot of useful info about the benefits of using this battery, in terms of additional hours in extended functionality, but it's all relative to your use and I typically recommend taking it with a grain of salt. The most important thing you have to realize is that once you are away from a power source and need to recharge your phone battery - you now have a portable source on the go. Also, a total advertised capacity of the external battery is not what you are actually going to see because it's based on their internal 3.7V-3.8V voltage which needs to be converted through 5V usb interface where you will loose some of this capacity due to a typical 85%-90% conversion efficiency. Therefore, you need to choose the capacity of your external backup battery based on how long you are going to be away from the power source and how many times you will need to recharge your phone or tablet battery.
With this explanation out of the way, let's take a closer look at the design and special features of UNU Ultrapack batteries. The design of GO and TOUR is almost identical with a piano finish top/bottom surface and softer material sides for a better grip. Both of the batteries have a power button which turns on a hidden LCD screen with a charging capacity info and also turns on a built-in led flashlight (convenient when you are in the dark, like during a power outage). GO features a single USB charging port rated up to 2.1A and TOUR feature a double USB port rated at 1A and 2.1A for a combined output of 3.1A. Another port they share in common is DC input charging port. Unlike most of the other external batteries with micro-usb charging port and a typical 5V/1A charging speed, here you have 12V/2.5A charging port which enables a much faster charging speed of the battery. Just keep in mind, we are not talking about faster charging speed of your phone/tablet battery, but the actual external battery itself.
Faster charging speed, up to 8x faster, means you don't have to wait hours to charge up this battery before you can start using it. As a matter of fact, it has a rapid charging mode where in 15min you get 2,000 mAh of capacity from empty. This means if you are in the rush you can still get a charging capacity boost for this backup battery in only 15min. The only catch is that you have to use a bulky wall AC adapter. It's the only drawback which is a price to pay for a fast re-charging. Another fantastic feature is the built-in LCD screen which tells you exactly in % how much battery left and also tells you how long before battery is full when you charging it up. When not turned on, the display is fully hidden under the top surface. Also, charging mechanism has it's own current regulator to optimize charging speed of your smartphone/tablet. With a smaller capacity GO, I was only able to charge my Note 2 at 1.2A speed. With dual output TOUR, Note 2 was charging at a maximum speed while S5 connected to another port only had 1.3A of charging current not to exceed a combined 3.1A output. It didn't even matter which port I had my phones connected to, either 2.1A or 1A ports were able to charge at max speed individually and current draw was regulated when two phones were connected simultaneously.
Overall, I was very impressed with performance of both batteries and all the additional bonus features they had to offer. Fast charging speed and a detailed LCD screen functionality was a very useful new feature if you are willing to pay premium price for these batteries. I know there are a lot cheaper alternatives with a similar or higher capacity, but you really have to factor in all the additional design features Ultrapack brings to the table in order to have a true comparison. And even so I typically don't review smaller capacity batteries, if you want this Ultra-X fast charging technology and LCD info screen but don't want to drag around a large and heavier TOUR, GO is a perfect solution for that.
Here are the pictures.
