Tattu 2in1 Power Bank with AC Wall Charger Review - Device Reviews and Information
Charge two devices at home or on-the-go with the Tattu 2in1 Power Bank AC Wall Charger.
When you combine a love of tech with an on-the-go lifestyle, power management becomes increasingly more complicated. Despite regular upgrades/updates, devices like our iPhones, iPads, Nintendo Switch must be charged frequently. With minimal use you may be able to get a day out of an iPhone, maybe a few days out of an iPad, but only a few hours out of the Nintendo Switch. One thing is certain; whomsoever improves our battery technology will be one of the richest people in the world. For now, we will need to continue to rely on wall chargers and portable batteries. Or, if you desire to space-saving convenience, you can use a hybrid device like that from Tattu.
Whenever I get a new item, I love to examine the box art, instructions, and product specifications. It would be naive to think that the packaging does not matter, but first impressions can make or break the sale. Unfortunately, the Tattu Power Bank/Wall Charger arrived in a rather plain 5 1/4 inches long by 4 inches wide by 1 3/4 inches thick cardboard box. I wanted to peruse the packaging and to learn about the device, but the shell was relatively devoid of information. Along the top left of the cover, you will find the “TATTU” title and along the bottom right an unrecognizable triple ink outline (thin, medium, and bold ink). This same trend was continued on the left/right panels, and the back panel only contained a few product labels and “Made in China.” The top panel was plain brown, except for two white stickers with a UPC sticker/model number and another with more product labels and product specifications. The stickers were the only piece of the packaging that was helpful. The main sticker detailed the AC charger/built-in battery, Model PST-17UPB-2, AC100-240V 50/60 Hz input, DC5V, 1A/2.4A output and a 5200mAh battery. Personally, the company needs to bring their packaging up to the quality of the device.
Inside of the box, you will find an attractive 2 7/8 inches wide by 3 1/4 inches tall by 1 1/8 inches thick glossy black charger, surrounded by white packaging foam. Aside from the hybrid charger and packaging foam, the box was devoid of accessory contents. Luckily, the product specifications were listed on the outer sticker and along the back panel of the charger, relegating the need for an instruction manual. Just above the product specifications, you will find a retractable Type A wall plug. The top of the charger flared out about 1/4 of an inch when compared to the bottom, to accommodate the foldable prongs. I liked the location of the Type A wall prong but felt that the product shape somewhat limited the use of the two USB ports along the top of the charger. When plugged into a lower wall outlet, the 1A output port was harder to access if something was plugged into the upper port on the wall. Since the 2.4A port was located further from the Type A wall plug, it was more easily accessible. I liked that the USB ports were oriented along the long axis of the charger, as this allowed the cords to angle outward. If the USB ports were oriented along the width (rotated 90 degrees) of the charger, they would have been essentially unusable. Perhaps it would have been better to place the USB ports on the face opposite of the Type A wall prong. When using the product with surge protectors or power strips, you may have to play power-cord Tetris if the prongs are oriented in parallel.
Along the front and back of the charger, you will find a silver/bronze raised sticker. I enjoyed the appearance of the sticker coloration upon the shiny black charger. The front listed Tattu along the bottom right and the back sticker listed “2in1 Design, 5200mAh, 3.4 A max for a phone (icon) and tablet (icon) and Fast Charging Detection.” Other than a small spacing typographical error “2in 1”, the well-placed stickers on the front, back and the hidden specifications beneath the charging prongs, greatly enhanced the feel of the product. To add a little artistic flair to the device, Tattu added six obliquely etched lines on the front/back of the charger. Pressing the power button, you can illuminate the small circular LEDs along the upper edge of the cover. There are four LEDs, which represent 25, 50, 75 and 100% available/remaining power.
My family and I like to do a lot of camping, both tent, and motorhome. When packing our to-go backs, weight is a prominent factor. Upon first impression, I thought that the 6.5-ounce hybrid device was rather hefty. However, when I compared the Tattu device to other batteries, I found that the weight was very comparable. For example, a similar 6000mAh battery from M-EDGE weighed in at 6.2 ounces. Interestingly, when I added the 2.2 ounces single USB Apple Wall Brick, the weight disparity became even more pronounced. The battery plus charger weighed more than the combo hybrid device from Tattu, making it even more pocketable. My only complaint about the power bank is that I typically want a battery to be at least 10,000 mAh. Assuming most batteries have an 80% efficiency, we can expect approximately 4160 mAh of useful charging capability. With the iPhone X battery capacity of 2675 mAh, the iPad Air 2 7340 mAh battery capacity, and the 8134 mAh iPad Pro 10.5″ capacity, we can assume roughly 1.5 charges for a phone and about 50% charge on a tablet. I typically like to have a battery that can charge my iPad Pro 10.5″ once.
To test the current, I used a DROK USB C Multimeter. When I plugged my iPad Pro 10.5′ into the 1A USB port (battery power), the device read 5.08V/0.95A. When I plugged it into the other port, the multimeter read 4.92V/2.34A. When I plugged my iPhone X into the charger, the multimeter read 5.01V/0.98A and 5.04V/1.35A respectively. For one of my tests, I plugged my iPhone X into the 2.4A port, pressed the power button and waited. Starting with 77% phone power at 10:17 PM, my phone was at 93% by 10:52, 95% by 11:02 PM and fully charged by 11:15 PM. Plugged into power, my iPhone charged at 5V/2A and generated roughly 1% per minute of power. When plugged into shore power, I was able to use the device as a power brick, charging my iPhone and iPad simultaneously. I was also able to use the 1A output for my Apple Watch charger and the 2.4A output for my iPhone X as well. I have used the device over the past one week as my main charger and appreciate the dual USB output. The weight to power output capabilities of the charger was very favorable and the ability to have a fully charged battery in 1.5 hours was even more exciting. Promising short-circuit protection, over voltage protection, over current protection, overcharge protection, over discharge protection, and pass through charging (charge the battery and your smart device simultaneously). Whether you need to top off your phone or keep it powered over a weekend, the Tattu device has you covered. With the two-in-one design, I will never again look at USB wall chargers the same way.
Pros:
1A and 2.4A charging
Pass Through Charging
AC Wall Charger and Power Bank
Charge two devices at once
Compact Size
Cons:
USB port placement limits use of other wall outlet
5200mAh may not be enough
Bland Packaging

Anker 2nd Gen Astro2 9000mAh Battery Pack
http://www.amazon.com/Anker-Portabl...?ie=UTF8&qid=1389368123&sr=8-6&keywords=anker Anker 2nd Gen Astro2 9000mAh Manufacturer Description Charges the iPhone 4+ times and large-capacity phones like the Galaxy S4 almost three times. Total charge output of 3A among two charging ports. One Smart Port (5V / 2.4A max) offers truly maximum speed charges to ANY device, including the iPad or even the Samsung Galaxy Tab. One additional port charges Android smartphones at full speed. High energy efficiency rate, 10% above previous generation Astros and many current standard alternatives, gives you up to an extra full charge for your smartphone. Sturdy construction and matte finish withstands bumps and drops. Grade A cells and premium chips ensure reliability. A "shake" starts a charge or displays the remaining power level. The ultra-low power consumption (100, 000 shakes consumes less than 1%) Smart LED display, designed with 10 LEDs, balances accuracy and aesthetics. Input: 5V / 1.2A; Use a 1.2A adapter for fastest charging time (8 hours). Packaging It’s simple and minimal which is a good thing. Also, the Packaging is recyclable for you ECO friendly people out there. Specs Package contents: Anker® 2nd Generation Astro2 External Battery, Micro USB cable, travel pouch, instruction manual. It’s about the perfect size for a battery pack. Easily handled with one hand, not too thick. Here are the output details for the two ports based upon the type of device you are trying to charge: Type of product-----------------Smart Port------Universal Port iPad IOS 5 and above----------2.4 Amps--------1.5 Amps iPad below IOS 5----------------2.4 Amps--------N/A iPhone IOS 5 and above-------1 Amp------------½ Amp iPhone below IOS 5------------1 Amp------------N/A Android Phones-----------------1.5 Amps--------1.5 Amps Android Tablets-----------------2 Amps-----------2 Amps Samsung Galaxy Tablets------2 Amps-----------N/A Other cellphones---------------1.5 Amps--------1.5 Amps Build Quality It’s made of plastic but of a very good build. It has a two tone look of glossy black ends with the rest being a matte black. It’s seemless from the transition from the glossy to matte. There doesn’t seem to be any gaps between the pieces. All ports are at on end. It has a ring indicators with 10 “pies”. Each pie represents 10% charge of the battery pack. It’s a nice soft white light and not too birght that a lot of electronics suffer from. It just has one Anker logo at the top and very minimalistic. Testing/Performance It has a Shake feature to activate charging. Simply plug in a device and give it a quick shake and the device and start charging. Now I know what you’re thinking; leaving it in your bag will discharge the battery for no reason if nothing is plugged in. That isn’t true, it has a super smart super low discharge even when left in a bag where accidental shakes will happen. I decided to test this out. Leaving it my baby nieces rocker, it didn’t even discharge 1 pie (10%) when left over 18 hours in the rocker. Using the following devices: Nexus 5 Nexus 7 2013 S3 Ipad 4 Ipad 2 Sansa Clip Zip Mp3 player All were able to be charged without a hitch. It is to note that the max output is 3 amps. So trying to charge two devices that require 2.1 amps is simply not possible at full speed. It would charge t but at a slow rate. It can charge a 2.1 and 1 amp device without a hiccup though. Either port would be fine for any smartphone under the sun. Using a Nexus 5 at 26%: 30 mins – 55% 1h 13 mins – 91% 1h 28 mins – 100% It used 3 pies (30%) to go from 26% to 100%. Conclusion It’s a great battery pack that has a nice shake feature! One of the better sized battery packs that has a good capacity compared to its size. A must have all tech warriors on the go. Note- I was supplied a sample for test and evaluation, and I promised that my review is fair and honest
Did you buy this or was it a gift from Anker for review?
This is a great device. I have the 13Ah charger, and it seriously holds a charge. I've never gotten it empty before because it'll charge my phone for a week. Looking forward to the next time I fly so I can use it.
Any chance you could actually test the output with a 12w ipad? I just got a new anker astro3, and it only charger at 2.1, not a 2.4amp Easiest way to test it is to download "batterylife"(free) in cydia, or time charging the default charger compared to the anker. Thank you! It is advertised everywhere as 2.4amp, but it seems like they do not have that feature!
Anker 40W 5V / 8A 5-Port Charger - Review
http://www.ianker.com/product/71AN7105-BA Manufacturer Description 5 USB Smart Ports auto-adjust charging speeds to charge phones, tablets or any USB-charged devices at their maximum speeds (up to 8A). The size of a deck of playing cards (3.6 x 2.3 x 1.0in) and unibody design for added portability. Industrial-grade plastic construction and premium circuitry ensure lifetime reliability. AC 100-240V input voltage ideal for international travel. Package contents: Anker® 40W 5-Port Wall Charger, 5ft / 150cm detachable power cord, user manual. Design/Build Quality Anker has changed it up from their previous 5 port charger; going from a glossy white to a matte black. The New charger has a slightly smaller footprint but mostly keeps the same design. The new charger has a two tone scheme where the majority is a soft matte black and the front port face is a glossy black. Upon closer inspection, its pretty solid in hand. Nothing bends or creaks when playing with it. It has a good weight to it. The matte black is somewhat of an oil magnet from your hands when touching it but nothing too serious. Overall, it has a great solid feel to it. Performance/Testing Unlike the previous white 25w version that had specific ports for specific outputs; this is a 40w smart charger. Meaning that any device plugged into any port will have the fast charging possible. That being said it is capped off at 8 amps total for all the ports. So you can't plug in 5 ipads and expect full 2 amp charging for each of the ipads, but 3 ipads and 2 phones will be at max speed. Testing it, it charged my devices as fast as the previous version and their oem chargers. It was tested with: Nexus 5 Nexus 7 S3 S2 Ipad 2 Ipad 4 retina Ipad Mini Sansa Clip Zip mp3 player External Battery Power banks All were charged just fine with no noticeable problem. Conclusion If you're like me and have multiple gadgets, a charger like this is a perfect companion for any tech geek. It's nice to be able to charge all my devices at one charger and not have multiple wall outlets over taken by chargers. Note* - I was given a sample for review in exchange for a completely honest review.
Review of amzdeal® 30W 4-port USB Wall Charger
http://www.amazon.com/gp/product/B00HJJPYXS I received one of these as a 'for review' unit but there were no under the table deals involving a positive review in exchange. This charger's distinguishing characteristic is that it comes with two 5V/2A ports and another two 5V/1A charging ports for a total of four. Unlike most USB chargers that try to be all things to all people and provide one 'Apple-optimized' and one 'non-Apple' port or one 1A and one 2A charging ports, therefore making them into 'single port' chargers most of the time, you can actually use all four ports to charge perhaps two phones and two tablets at the same time and this is a good thing. For your money you get the charger body that comes with a status light and non-foldable prongs that plug into standard AC outlets. You supply the USB cables. The 2A outputs are better suited for the larger devices such as tablets but I found that it charged our phones as well. It even charged our HP Chromebook 11 which is happiest when it gets 3A but accepts anything from 1A up to 3A. I can't think of no 'negatives' for as long as you are not looking for something 'small' or 'portable' in which case you should be looking elsewhere. The price is so cheap!
This was sent to me for review. A very professional correspondence with amzdeal who have clearly created a great product and want to let the world know about it. There was no pressure to write a positive review. Firstly, I should say that I would have given the product 5 starts were it not for the arrangement of the charger. The charger could be certainly be smaller. As it is, it sticks out from the wall by a few inches which means that it won't fit behind a nightstand. If the prongs were on the side of the device, the charger could sit more flush with the wall. As it happens, I don't have a nightstand and I normally leave my phone and tablet charging, beside my bed, on the floor. With this style of charger, I can actually rest my phone on top of the charger instead of the floor! The charger has 2x2A and 2x1A USB output. This allows me to charge my tablet and both mine and my wife's phone, all from the same wall socket. I actually put my phone into a 2A output and it chargers just fine, at double the speed. The led light indicates when the charger has power, i.e. my bedroom switch for the nightstands is on. It is a very useful feature. I have been using it daily for 2 weeks now and am confident of its quality build. In summary, a very good product but not for use behind nightstands.
EnerPlex Jumpr Slate 10K Review
I picked up this thin 10,000 mAh power bank last week at a kiosk in the Cherry Creek mall near my house. I was in the market for a small and powerful powerbank to keep my phone and tablet charged throughout the day and found this is a great solution. Here are my thoughts: The Jumpr Slate comes extremely well packaged in this orange box. On the front is the usual branding it states that it is a 10,000 mAh powerbank with 2x 2.4A outputs. The packaging looks and feels solid. On the back of the box are more details on what sets this powerbank apart from the pack like an industry leading 93% power transfer ratio, its light and sleek design at 6.7mm thick and only .77 lbs, and a badge showing that it meets worldwide safety standards (UN 38.3). There is also a list of devices that can be charged with the Jumpr Slate 10K. The overall design of the Jumpr Slate is very nice. It is only about a half inch thick and the pattern on the top is simple yet provides a clean and industrial look, as well as providing a nice texture to grip onto. The binder holes on the side make it easy to conveniently clip the Jumpr into a a notebook, and the thin design means it takes up very little space in a tablet case or briefcase. There is the EnerPlex branding in the corner but it is not over branded or too in your face. On bottom panel there is a mini USB input to charge the Jumpr, and two 2.4A USB outputs. There is also a small button for turning the Jumpr on/off, and 4 LED indicator lights that display the amount of charge that the Jumpr has left. To test out the Jumpr Slate 10K I let the battery in my Galaxy S4 run all the way down and I then used the Jumpr to recharge it. It took about the same amount of time as charging from a wall outlet, same with when I plugged in my GoPro. After charging both devices the indicator showed 50% battery life left on the Jumpr.... not bad. PROS: Charges devices as fast as outlet Extremely thin and light 2 USB Outputs CONS: Will not charge laptop Recharge time of about 10 hrs Overall I love this thing and it has a permanent home in my computer bag. I also bring it with me to provide a backup charge to my GoPro when adventuring in the Colorado Rockies.
[Review] Lumsing Glory P1 Fit Powerbank Review
Overview Quick summary - great little device really solid and well balanced with three output slots to charge two devices. The hugh 10,000mah it enough to keep several devices topped up for quite some time. Despite its capacity its not too heavy, mine weighed in at 246g / 8.7oz). Unboxing So in the box is the battery pack, a short black USB lead and the instructions. The battery pack has a really large capacity at 10k mah which is enough to charge a Galaxy S6 up a few times before itself requiring recharging. The battery pack is black plastic body with orange plastic trim on the top and bottom. There is three USB outputs all at the top of the unit. Despite the capacity of the internal battery the weight of this doesnt feel too bad, weighing in at 246g which is really isnt that heavy and the slim profile means that it will slot into a jeans pocket no problem. On the front are 4 little blue LEDs which light up to show the capacity. In theory each dot should be enough to deliver 2,500mah of juice so in theory each light of power should easily charge any modern smartphone, just for reference the capacity of my Galaxy S6 is 2550mah. On one side is a plastic button you can press to view the charge or turn the pack on when you want to start charging a device. Lumsing doesn't specify the rating of each, but the device's maximum power output is 16W. That means with three devices connected charging will be pretty slow, with just 5W available from each. Testing out each port with Ampre the average output for my Galaxy S6 was 1000ma, it charged my S6 fairly quickly (about 1 hour 30) from nearly empty so the device delivers a amount of power from each port when charging a single device. Overall I really like this pack, its nice, solid and premium feeling, works well and having three output ports is always a plus and pretty handy with lots of devices being USB powered, thi feels like the main selling point for this device. I can see this being used by people away long long trips or away camping or hiking where there is no access to an outlet to keep your smart device topped up. I really like the slim design which means it can fit in a pocket nice and easily.
