Anker PowerCore Ultra Compact High Speed Technology

My friend Melody McCauley say The battery pack would not fully charge. I tried ....

The battery pack would not fully charge. I tried using it and it only gave my phone 1.5 charges, it should have been over 4 charges. I tried to charge it again and it would only charge a quarter of the way after 24 hrs. I got a lemon and returned it.

My Old Fellow willyoung29 experience Life expectancy is two months and lacks quality control.

This portable charger worked as described for two months and then it stopped working completely. I never over charged it and I used it sparingly. Now, it will not charge-up, turn on or charge any device. It has totally failed. I purchased two others in May and they also failed after a few months. This product appears to have a design flaw and lack quality control because the life expectancy is less than advertised. I rate it 1/2 star.

My friend Amazon Customer said Disappointed.

I'm pretty disappointed with the charger. I've had it for less than a month and used it probably a total of 5 times. It no longer holds a full charge. I charged it overnight thinking I needed to charg it for a longer period of time, but that didn't work either.

My friend Anthony Deggelman say Doesn't Work.

Terrible. Charger doesn't even charge my phone. Even with all apps closed it drains battery. I tried turning my phone off and charging it and it estimated 5 hours to fully charge it. My phone was at 80%. Don't waste your money.

My Fellow Holly P said Worth every penny.

I've had this power cell for almost 1 year. I left it on my car for a few months in variant weather and never charged it or used it. This morning I plugged it in for maybe 45 min and it was 1/2 charged. My phone went down to 3% and I got terribly lost in an unfamiliar place and needed to use Google maps and I knew that would kill my phone. I plugged in my phone to the charger and walked for 20+ minutes using my phone ,and got to where I'm going. Then left my phone to charge more and it charged all the way to 80% before running out of juice. I am very impressed that even sitting without use and in a hot car, this thing still worked great. I feel like it was definitely worth the money and am so glad I bought it.

My Old Chap Patrick tell us Free Yourself From the Wall Outlet.

If you're looking for peace of mind every time you leave the house, this power bank doesn't disappoint. It's the size of a credit card and only a hair heavier than my iPhone 6 making it extremely portable without being bulky and heavy. There's a power button you press which shows how much power is left via 4 blue leds (when it's dead, only one led will flash). You can only charge one device with this power bank but I'm always impressed by how quickly this charges my iPhone 6 (from 10% to near full takes approximately 1 hour). So far, I've been able to charge my phone about 4 times from near empty to full before having to charge the power bank. It comes with a usb cable to charge the power bank itself as well as a drawstring pouch. Since I hate carrying around the long original lightning cable from Apple, I bought the 1 foot "Double Braided Nylon Anker PowerLine+ Lightning Cable" which is the perfect size.

What I love the most about this power bank is how effective it's been. The power bank itself requires at least 2 hours to charge from empty to full but once charged, your phone will charge to full in less time. As a result, I haven't charged my phone using a wall outlet since I bought this power bank more than a week ago. Not having to worry about my phone going dead or being near a wall outlet is the best feeling next to purchasing a new phone.

So if you want a reliable power bank that charges your phone in no time and frees you from being attached to a wall outlet, GET THIS!

My Old Chap piyawan chantakasem say It worked fine the first time to had to recharge it.

I ordered and received this item on January 4th 2018, it’s been less than 3 weeks and the charger is already not holding the charge. It worked fine the first time to had to recharge it, but now it doesn’t even charge.

My Old Man HappyCustomer say Disappointed.

Worked great for a couple of months... now it has one bar after a full night of charging. Disappointed.

My friend Elad experience Tested for actual capacity, Dimensions are small!!.

All Lithium batteries are 20-25% off the mentioned capacity:
If you don't care why you should skip this section!!!
**********************************************************************
A little good-to-know fact on batteries:
Lithium batteries are 3.7 V and USB ports are 5V, to convert 3.7 to 5 you are gonna lose some juice- about 20-25% of the battery's mentioned capacity.
That means the actual capacity here should be around 7500 mah (again, almost all batteries actual capacities are 75-80%).
*********************************************************************

You can see that by seller description: 2.5 time Samsung galaxy s8 is 7500 mah.
good thing is that I checked the actual battery's capacity and it is really 7500 mah- so the seller is obviously honest here.
PROS:
- It is really small! see pics
- actual capacity tested for 7500 mah.
- can handle 2V both when charging or being charged.
- it came with nice case and perfect length micro USB cable (pics)
- It also works with apple: tested on iphone 7 and 8+ with no issues
CONS
- you are paying mostly for the compact size (at this price you can get some quick charge batteries).
- input is 2A, so basically if you know your charge can do 2A it's gonna take 5-6 hours to charge it, otherwise, its gonna take 10-12 hours by 1A charger or a full day via computer port.

summary:
If you want a 7500 mah compact size battery you can carry in your pocket this one is the real thing.
If you care too much on charging your phone fully in an half an hour- you should probably look for a battery compatible with your phone's quick charge standard.

My Old Fellow Sway Talk Great charger.

Update: I’ve had this for like two years now. Still works great! I’ve taken it on so many trips. I’ve been able to charge my iPhone, and GoPro batteries all with one charge. This thing has been a great purchase.

So far so good. I've used it a couple of times and I've been able to charge my iPhone 6S at least 3 times with one charge. I really like the light that tell you how much power is still left. It's also pretty small so it doesn't take up a lot of space.
