Review: Legendary Anker product and service! - I’ve been a fan of Anker products for a while now and they’re my first choice brand. Excellent quality products and value for money and backed up with first class after service for peace of mind. Simple yet robust. It charges my devices quickly and is more than enough for me to use out and about for a number of days. I don’t stress out anymore with this by my side. It’s not the fastest in charging up but understand it’s better for product longetivity. Fine by me and just plug it in overnight and good to go by AM. What sets Anker apart is the after service if anything goes wrong. I’ve seen it reported by other people and I got to experience it recently. I had found the micro USB connection for power input always a tad loose from the beginning. I let it go as I could get by. Then it reached a point where it was difficult getting a secure connection. I sent Anker an email with a description of the problem. Initially I asked for just a new cable because a different cable did help make it better and I didn’t want to get into a bun fight. Anker asked me a few questions to ascertain root cause and concluded the port was faulty and sent me out a brand new powerbank very quickly! Wow! Am very impressed. A company that didn’t just do the bare minimum but wanted my compete satisfaction. You’ve certainly got that. Well done and thanks again Anker! Update: 7 June 2019 I bought the original back in July 2018. A replacement as per above was sent to me due to Micro USB port being faulty. Gave great service and the unfortunately the replacement developed a fault when whilst charging it would stop after a few minutes. Contact led Anker and again they responded quickly and sent me out a new one with no quibble and very quickly. They were naturally disappointed that I had to contact them again and I accept that it is rare occurrence. Very happy with the after service of this company and they’ve come through for me again.
Review: Great, but don't overuse. - The powercore has been a great device, although there is one small defect that I will explain. It was originally bought for use at festivals and was perfect for this purpose. The device supports fast charging and took about 90 minutes to give my phone a full charge and this would lose perhaps one of the blue charge level lights. I expected to get 4 full charges and still have enough for maybe another half typically, it could then be left to charge overnight with a festival locker and I had the ability to look after myself and friends all day. Admittedly it is quite bulky and heavy but that's the price you pay for it's MAH (milliamp hours), but you do get used to just putting it into an inside jacket pocket and forgetting about it. I found it totally durable as after 5 festivals during the season it had nothing more than a few light scratches and worked perfectly, even after some wet weather and some alcohol spilled on it. A quick wipe down and it was sound. I came to rely on it so much that I took it everywhere I went if I thought I may be away from a power point. Now we come to the issue. After a little over a year the device would no longer accept charge. Perhaps it was a fault in the usb socket or a short inside, I can't say, but after trying multiple charge cables and power bricks I was beaten. In defence I do believe the device had been used enough times to warrant a high use moniker, above what is typically expected. A quick email to Anker and after a serial number check they were happy to replace the device without hassle. They didn't ask for the previous device back, likely as it's not worth the cost of shipping. This approach may of been useful to find out what caused the fault and rectify it for newer models but c'est la vie. It took just 2 days to get the replacement and it's great to have the old friend back to rely on. Can't fault the service.

## Questions & Answers

**Q: Can you charge the PowerCore whilst its charging other devices?**
A: No you cannot. Don,t know why some people say they can, probably they just assumed that, whithout actually trying. Because of some wrong answers, I thought that myself and I actually bought the device because of that. So please people, answer correctly and stop misguide buyers.

**Q: how long does the anker powercore 20100 take to charge**
A: According to anker .... 10 hours to charge on a 2amp charger or 20 hours on a standard 1amp phone charger. That being said its usually faster than that.

**Q: Does it come with a charger?**
A: No charger supplied .It comes with a lead that can be plugged into a USB plug or into USB port on your computer.

**Q: It only charges my iPhone 5 2-3 times, is mine faulty?**
A: Remember that with any charging source capable of delivering enough amperage to charge a device in use, the internal battery on device charging basically becomes a power 'sink'.  Roughly translated, because the draw under such a scenario draws a relatively high current from the battery, if you charge whilst device is in use so it's effectively topping up the battery charge, most of the delivered energy actually gets soaked up/used by the active demand of the device.
So, if you use the device with the powerbank attached, both the power demand and charge demand effectively sources from the input amperage available from the power bank.

It's the case on most devices you can charge without switching off to charge.   If you turned off the device (aka powering off to a very low inactive state on most device lacking a physical power switch) on most non power switch enabled devices, you'll only be charging the device from the PB, where the input is only charging the battery effectively as the idle/sleep demand by the device is low enough to just draw from the battery and the battery becomes the higher demand rather than the device.

With devices that physically switch off and you charge in the true off state, you'll see the potentially number of available full charge cycles being about what the PB is rated for.

So in short - you'll never see the full amount of device recharge potential as rated for the PB whilst you are actively using the tethered device whilst it's charging - because your tether device is drawing from the battery as a sink, the battery gets charging current from the PB and because the overall demand is high, effectively the PB becomes the power supply for both device actively and the battery.  You'll also notice, if device battery is low, the charge time increases because of the imbalance whilst the battery gets charged whilst acting as a sink.

But ultimately, any specification rating on such devices is a bit variable in practice as the PB is doing power regulation of the internal battery or batteries and output of the PB, and given the regulator board (probably a buck type converter) draws current and translation of source (PB's internal battery voltage) to the actual output voltage isn't 1:1, power is consumed by the power regulation process which (in most cases today) generates a pulse modulated square wave output of n-100% duty cycle depending on tethered demand.  At 100% (effectively continuous output) duty cycle, more power is consumed from the PB's internal battery pack than the actual output power available to the device tethered.

### ⭐⭐⭐⭐⭐ Outstanding Product!
*by H***T on 26 October 2016*

Purchased this product before travelling around Sri Lanka with friends for 2 months, and it was possible the best purchase I made before I left. I had previously used a cheaper recharging power unit, which had one or two recharges on an iPhone maximum, and felt like cheap quality plastic too. This on the other hand exceeded my expectations in every department. Design and Build: Whilst it isn't the most sleek of things to look at, it is far from the worst looking device on the market. The device is slightly large but not too big as to be an inconvenience, and can comfortable be carried in a bag. If you were wearing certain trousers you could get away with carrying it in the pockets, however it wouldn't be the most practical of options. The device is solid, very solid. As a result it's quite a heavy product for its size, however its unnoticeable when put in a rucksack. There are two USB ports, which was very practical for when both me and friend would need a device charging, or if like me, you have a tablet and a phone, where both need charging at the same time it is more than capable of doing the job. Charging: I was astounded at how good the charging was on this product. It charges devices faster than plugging them in to the wall socket! Not only this but I was amazed how much use you get out of it before it needs recharging, I think the maximum I got out of it was 9 or 10 charges of an iPhone which was below 5% power each time. In addition to this, plugging in a second device to the other USB port appeared to made no difference in charging speed to either device. Recharging the Anker itself can be quite a lengthy process if it has no power, and I've found it varies how long it takes to recharge. I have found it recharged in under ten hours at times and over 12 at other times, however the majority of the time it was inbetween the two. Conclusion; For the price this product is nothing short of incredible! Especially if your going somewhere where you will be away from an opportunity to charge devices such as a day out, camping, or staying in hostels or hotels where plug sockets may be limited. Due to the massive amount of charging it can do before it runs out of battery, it can easily be shared be friends and family. Highly recommended product, with all things considered such as prices charging ability, and design, it's hard to find a better product on the market at the moment.
