This is a review of a power bank from Intocircuit - http://www.amazon.com/gp/product/B00OSYLXKU
As phones have been getting more and more powerful over the years, portable battery packs for smartphones and tablets have been gaining popularity. There’s many different brands and variants available, and today we’re going to be having a look at a 15000mAh power bank from the company Intocircuit.
The power bank itself comes in a small box with some product information on it regarding the amperage and capacity, and inside there’s also a USB-cable and a small pouch to put the power bank in. The accessories are of decent quality and definitely are nice additions to the power bank.
So when it comes to the actual power bank, it’s made out of a combination of plastic and brushed aluminum – it really looks nice and a bit different compared to other brands. The power bank has 2 full-size USB ports that are rated at 2.4A, a MicroUSB-port that can be used to charge the power bank, along with an LED and a small LCD display that show the amount of battery that’s left.
When it comes to the actual capacity I must say that it’s pretty much spot-on, as I’ve managed to charge my Yoga 2 tablet (capacity: 9400mAh) and my Z3 Compact (capacity: 2500mAh) using it, before the battery of the power bank was fully drained. The recorded output current while hooked up to my Yoga 2 was stable at around 2A, and with a quality USB-cable reaching 2.4A should be certainly possible.
The main negative thing that I’ve to say about this power bank is the fact that it takes a long time to charge it up once drained, but that’s due to the higher capacity and other power banks such as the Xiaomi 16000mAh suffer from this as well. Charging the power bank 0-100% takes nearly a day, and therefore it’s a good idea not to let it drain completely before charging it.
So conclusion time – this is a pretty decent power bank for the price and it looks and performs great, and is comparable to other brands that I’ve tried in the past. The capacity is correct and the charging speed is decent, although charging the power bank itself takes some time. This is certainly a product that I do recommend if you’re shopping for a good power bank!
Pros:
- Good battery capacity and power output
- The included accessories (pouch, micro-USB cable)
- Decent build quality, and the power bank looks and feel great.
Cons:
- Takes a long time to charge up
Note that I was provided with a review unit of the above mentioned product, but that does not affect my review as it is solely based on my own opinion and experience.

Depending on how much your Raspberry Pi draws, let's say 1A, I would say about 11-13 hours at most.
Nice review. It's always good to have a back up power bank with you especially during a trip.
Can you charge the battery pack at the same time as it is charging other devices?

I'm not entirely sure about that as I've not tried it, but I think it may be supported.

This is a review of NewTrent NT120C CarbonPak 12000 mAh external battery: http://www.newtrent.com/carbonpak.html
High capacity external batteries are becoming very common these days, more affordable, and smaller in size thanks to evolution of battery cell technology. What is great, and speaking from a personal experience, they can be used as little power hot spots when you need to charge up your device on a go and nowhere near the power outlet. Or another use I found, whenever I'm using my android on-a-stick connected to tv - I no longer need to run power wire from outlet, just connect external battery and that's it. I decided to review the new NT120C model because it offers all these benefits at a very affordable price.
Measured at 258g (9.1oz) it's not the lightest, thus not exactly very pocket friendly. But it has small dimensions of about 110mm x 75mm x 20mm which is very impressive for 12000 mAh capacity external battery. The top and bottom finish of the battery is piano glossy, but don't count on it to stay that way for a long time since your fingerprints will be all over it On top you get a power and led indicator line. I guess something new and original from typical 4-5 leds, this one has a lightpipe partitioned in 4 segments corresponding to 25% battery increments. The battery itself is very straightforward. You get micro usb input which charges the battery at 1A and also will mean about 12hr of charging time. And you get 2 full usb outputs, one labeled as 2.1A and another one as 1A. The lines between Apple and Android are blurred in this one, and obviously our Note 2 will benefit from a faster 2.1A charging. You can charge two devices simultaneously, very common with such dual output external battery. The real capacity will be closer to 9000 mAh or slightly below because you will loose efficiency during 5V usb conversion, another common thing with all the batteries. One additional bonus feature of this battery is that it should continue charging your phone beyond hitting 100% mark. You know how you typically read about keeping phone on a charger for a little bit longer so you can get extra juice. Apparently this battery will allow the same functionality. (*** edit *** I confirmed our Note 2 stops the charging at 100%, and doesn't allow this external battery to overcharge it, so this feature doesn't work with Note 2. not a biggy anyway).
Overall a solid battery, and considering my previous experience with NewTrent products, I trust their quality. Not too many external batteries I trust or recommend (and always encourage to stay away from any ebay no-name part), but this one is definitely one of those that gets my recommendation.

I always needed a power bank for my Nexus 5 because it dies really fast when I have LTE, GPS on using navigation or taking pictures on any tours. I came across to this one in Amazon, Vinsic Tulip 3200mAh Power Bank. I am very happy to say that I am more than satisfied with the quality and effectiveness of the product. It got delivered in 3 days and also available in Amazon Prime.

Features:
Powerful 3200mAh external mobile battery charger
Ultra slim alluminum alloy body
Designed with a 5V 1A output USB port
Built-in 4 LED indicators to show the charging status and battery level
Compact size which saves space and convenient to carry anywhere
for iPhone, iPad, iPod, LG, Sony, Samsung devices, HTC phones, digital cameras, game consoles, MP3/MP4 players and more.
It supports over-charged, over-discharged, over-voltage, over-current and short circuit protection, safe and reliable
First Impression:
After I opened the box of the product I found out that the power bank is charged up to 3 battery level light indicators. I charged it to 100% and to test I connected my Nexus 5 with it. It took little over than 75 minutes to charge my phone. Then I connected the power bank to my charger to recharge it for future usage. It took just more than 2 hours to charge it to 100% as I could see the battery level light indicator which helps you greatly to keep a track of the power level. I definitely think this product does its job perfectly and on time and it is a very useful product for someone like me. Now I don't have to panic about my phone dying when I am on any trip.

It seems great, I order one and the I will put a review too.
_____________________________________Read more write less and be smart
Siggey let me know about your review as I might be interested in one, I was just looking at the 20,000 Mah one as well.
how long it takes to charge Samsung S6?
I like this unit since its just big enough for a full charge or just a quick top off but easy to carry around
This charger is nice so far I got the 6000mah one its nice small and charges the s6 edge fairly quickly.

My Review :
I got this power bank for £29.99 from amazon and i think its worth every single penny. And I really like the high quality build of this power bank with matt finish. It charge my phone in 1 hour 45 minute from 0 to 100(S6 ) and This power bank’s high power capacity makes it great for charging multiple devices, especially considering its USB charging speed 2.1A output.And it allows me to charge my phone 3 time from 0 to 100.
The first thing you notice about this unit is it’s size ,weight and it cool designee . Believe me at this point I thought there is no way this device roughly the size of a smart phone could possibly jump starter my car. I've always used a heavy, bulky and cumbersome 18kg jump starter/battery pack, so it's hard to believe something measuring just 18 x 8.5 x 4.5cm and weighing 617g (vs 18kg!) can perform the same role - but it does!! I tested this unit on a standard car battery AND a van battery and both started perfectly ON ONE CHARGE!!
I've now used a few of these compact jump starters, been impressed by the performance of them all and they have each started our 1.6 Citroen Berlingo, 2.0 Diesel Renault Laguna and 1.4 petrol Megane. Of them all, however, this one seems to be the best, most powerful and it's the only one to include a red warning lamp to indicate a hazard - essential for roadside breakdowns.

:good:great review
Overview
Quick summary - great premium device, really solid and well balanced with two output slots to charge two devices. The hugh 13,400mah it enough to keep several devices topped up for quite some time. Despite its capacity its not too heavy.

Unboxing
Firstly I’d like to point out that im not associated with Lumsing, I work for a big pharmaceutical company, I just enjoy technology and writing reviews on things.
So in the box is the battery pack, a short black USB lead and the instructions. The battery pack has a monster 13,400mah which is just insane and enough to charge a Galaxy S6 up a few times before itself requiring recharging. The battery pack is gold metal with plastic on the top and bottom, the feel of the device is really premium and solid feeling like it could take a good knock should you drop it. Despite the capacity of the internal battery the weight of this doesnt feel too bad, weighing in at 260g which is heavy but doesnt feel like much more than some of the smaller battery packs ive reviewed. The battery pack feels very well balanced and isnt heavy down one end or the other.
On the front are 4 LEDs which light up blue to show the capacity. In theory each dot should be enough to deliver 3,350mah of juice so in theory each light of power should easily charge any modern smartphone. On one side is a button you can press to view the charge or turn the pack on when you want to start charging a device. On the top is an LED for which lights when charging the pack, a micro USB input and importantly two USB output sockets, adding to this devices versatility - the ability to charge two devices at once. The max output in total across both ports is rated at 3A, the output from each port isnt listed and it isnt listed if one port supplies more power than the other. Testing out each port with Ampre the average output for my Galaxy S6 was 1200ma, it charged my S6 fairly quickly (about 1 hour 20) from nearly empty so the device delivers a good wack of power.
The little micro usb lead supplied is a fair length, long enough not to have my phone right on top of the battery pack. Also a nice plus is that the supplied cable also works as a data cable, something that doesnt always happen with battery packs.
Overall I really like this pack, its nice, solid and premium feeling, works well and having two output ports is always a plus. 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. The weight and size means that this would fit nicely into a pocket or backpack no problem.
I really like this and its my new replacement camping device to take when I go away

Unboxing
The Power Bank comes with an eco-friendly packaging and basic accessories: 1x Micro-USB Cable, 1x User Manual, 1x Warranty Card and the Power Bank (of course).
Its chassis is made of Plastic, pretty solid and it reminds a sort of Modular design (it isn’t modular though).
On the front, there is a Power Button with a LED, used to check the battery level.
It is pretty smart, as you can see from this image.
There are 2 USB ports available, with 5V/2.4A output, featuring the usual technology called “AIO” from AUKEY that works on the voltage depending on the attached device. Follow my next paragraph to know more. There are two types of USB inputs: Micro-USB & Lightning.
Together with the USB ports, there is also an useful (even if not extremely powerful) Flashlight that can be turned on by long-pressing the Power Button.
As regards the size, being a 20000mAh battery, it is bit bulky and heavy, but it is rare to find something smaller with the same capacity.
Efficiency
All tests have been done using AUKEY’s Cables, in order to get maximum efficiency and to avoid any possible issue.
I have tested the “AIO” USB Ports using my USB Capacitor (1A/2A), and the voltage seems to get a bit too much low on high-load. Unfortunately this is a common issue (well, it isn’t a real issue, but a limit), so you can’t expect the same voltage that you get using a standard AC charger.
I have measured its capacity using my USB Tester, and sincerely it disappointed me a bit because real capacity is considerably lower than declared. (20000mAh vs 16664mAh)
While charging, it reached just 37°C, the coolest power bank I ever tried.
Conclusions
Well...its hard to express an opinion about this power bank. It is solid, smart, but it isn’t perfect. Battery Capacity doesn’t match declared value (at least on mine) and there is no Quick Charge support, but it has a Flashlight and a Lightning input for Apple users.
So...do I recommend it? If you are an Apple user, and if you don’t mind about Quick Charge, then Yes, otherwise just go for something else, such as the smaller (16000mAh) variant with Quick Charge or other brands.
Pros:
- Flashlight
- Lightning Input
- Solid
- Smart Power LED
Cons:
- Real Battery Capacity is lower than Declared
- No Quick Charge support
Rating: 8.3
Packaging and Accessories: 7.5
Design and Materials: 9
Performance and Efficiency: 8
Price: 9 (based on Amazon price)
Official Product page: http://www.aukey.com/product/PB-N36
You can find full-res images (I know, Quality isn't excellent) here: http://imgur.com/a/v800H
Cons:
- Real Battery Capacity is lower than Declared
- No Quick Charge support
You did not consider the DC/CD conversion ratio and efficiency. The manufacturer states that the power bank has 20000mAh capacity @ 3.7V nominal battery voltage.
That's 74Wh. It's written on the case.
You discharged 16664 mAh while the output voltage was 4.85V. That's 80.82 Wh. Already higher than 74Wh.
But the DC/DC conversion efficiency is lower than 100%. It should be somewhere 85% and 90% since Aukey is using very well built synchronous converters.
So the real energy pool of the power bank is somewhere between 89.8 Wh and 95.1 Wh before the conversion.
At the nominal 3.7V battery voltage that's between 24270 and 25700 mAh.
Which means that in fact You got a much better battery than specified.
Quick charge is supported in PB-T5 ( QC 2.0 ) PB-T10 ( QC 3.0 ). These are the same power banks but equipped with quick charge ports.
Dont't expect quick charge when You purchase the only model from 3 similar which is intentionally not quick charge capable.
Thanks, good review.
