Works with Vive Wireless VR

Reviewed in the United States on October 9, 2018

Verified Purchase

I bought this to use with a vive wireless VR. Yes, this actually fits in the holster. It's a snug fit though. Don't jam it all the wall into the holster. It will be difficult to get out. Better yet, don't use the holster at all. Just place the batter pack in your pocket.

Camping Approved

Did tons and tons of research before pulling the trigger and mega pleased by this charger. When I received it, it was about half way charged, and charged it for another 24 hours before taking it camping for a few days. I charged my S8 4 times and barely dented the battery life of the charger. Very pleased.

Stopped charging past 2 lights and sounds like if a capacitor shorted out

Reviewed in the United States on May 9, 2019

Verified Purchase

I bought it on February and used it like 2 times with no problems so far. But when I tried to charge it back to full now it doesn't go over 2 blinking lights and I noticed that there's some noise coming out of the unit while charging, so there must be a problem with it. I let it charge with a regular 5V/2A wall charger for over 6 hours while I was outside of my house and when I came back it was still showing only 2 lights on and charging.

I don't know if this is a common problem or if I was just unlucky to get a faulty unit, but now I don't have anything to charge my phones while traveling which is a shame after paying 60 bucks on a faulty unit. Less than 3 months of use and it's now dead. I hope that the 18 months warranty period comes to rescue.

- Update: 6/18/2019 ------------------------------------------------------------------------------------------------------------------

Using the replacement unit sent to me about a week ago. No problems so far, I hope no more problems and be just another happy user. I'll keep posting regular updates on this subject. Thanks for the fast response Anker!!!

Buying for second time

Reviewed in the United States on September 15, 2018

Verified Purchase

I had a previous model of this battery pack that worked perfectly (I gave it away and still runs fine). It's very useful during trips. You never run out of battery, specially when you have a portable wi-fi device. Usually those, with their own power, run out in the afternoon. With this, I could run the wi-fi all day and recharge any phone we carried.
Yet, I miss the led light that the previous model had.

Takes too long to recharge.

Reviewed in the United States on August 30, 2018

Verified Purchase

Upon receipt I charged it up which took a few hours but not surprising if it had no juice at all. The second time I charged it was plugged in overnight and was not fully charged in the morning. When I got home that evening plugged it in again and a few hours later the lights were out. Then ran it down by using it to charge everything. Plugged it in last night and this morning the third light was blinking, not completely charged after overnight. I've got it charging again right now, but I can't have it taking 12 or more hours to fully charge. It's supposed to help me charge on the go, but there won't be much of that if I can't unplug it from the wall.

Awesome product! A must have for travelers!

Reviewed in the United States on September 14, 2018

Verified Purchase

Amazing! It charges your device fast! It does take a while to charge the actual battery bank but I charged it left it for a week in my bag, charged my phone from 10% to full put it back in my bag for a week charged my phone again and it's only down 1 bar of charge! If you travel often it's a must have charger.

I've had a handful of other smaller power bank and they all seem to be fine at first and then they wear down fast. Never seem to get a full charge out of any of them and for good reason... They are small and don't put out a lot of charge but in my opinion Anker makes some if the best chargers. Never had anything more reliable than this bank. Be awesome if it were waterproof but I can always put it in a dry bag making it the most awesome charger ever!

Great product! Well worth the money!

Bad quality control -- mine's a dud!

Reviewed in the United States on March 17, 2018

Verified Purchase

I'm pretty sure I've received a faulty device. I've fully charged it, and I've tried tons of cables over the last few days, but as soon as it's unplugged from power, it seems to be a dead device again. Hitting the button does nothing, not even lighting up the indicators to show how much power it has, and it will only deliver a charge to my devices while it's actively charging itself. That completely defeats the purpose of a portable charger.

Super heavy and a little bulky but I never leave ...

Reviewed in the United States on August 17, 2018

Verified Purchase

Super heavy and a little bulky but I never leave home without it especially during the weekend trips.
Furthermore, I use this when I'm home also when I need to be on the phone without having to sit next to an outlet while my phone charges.
This charges my phone/table so much faster than when I plug it into an outlet.

Fast charger for my phone, earphones and laptop!

Reviewed in the United Kingdom on October 1, 2017

Verified Purchase

I use this charger on a regular basis and it's brilliant! It does what it says on the description. Comes with power IQ and Qualcomm Quick charge 3.0 which both charge my phone at the same rate as my fast charging plug. I also use this to recharge my asus laptop which actually charges faster than the wall plug it came with thanks to the adaptive voltage technology!
The charger comes with a cushioned sock that provides a bit of protection, I plug the micro USB cable in and tuck it within the sock so I never lose or damage the cable! [Shown in picture]
It's 3-4 cm longer than my phone so still fits into my coat/jacket pockets with ease!

Cons:
A more detailed battery level indicator would be useful, it has 4 little LED lights which are good enough 99% of the time but it would be nice to know the exact charge I have left when I am below 25% capacity so I can be more conservative if necessary.

High speed portable charging, yes please!

Reviewed in the United Kingdom on February 26, 2018

Its great

I actually have two of these that I use and I can honestly say I am impressed, It charges my smartphone just as quick as the original mains charger does, and this can charge my phone 5 times before needing a charge itself.

The only downside I could think of is the input charging port not being USB-C as so many other mains chargers I have now all feature this.

Also bag it comes with is a nice touch, all in all Im very happy and have no issues with it whatsoever

Works directly with HTC Vive Cosmos Elite, for longer uninterrupted gaming power

Reviewed in the United Kingdom on August 24, 2020

Verified Purchase

Works with HTC VIVE Cosmos Elite. Amazon has a habit of mixing up reviews so ensure this review is for the ‘Anker [Upgraded] PowerCore Speed 20000, Qualcomm Quick Charge 3.0’ with the word speed after PowerCore and the all important QC (Qualcomm Quick Charge) 3.0.
With the HTC cradle in the locked position, the battery slides in nicely and holds quite firmly.
Unsure at this point total battery life; however, after a couple of hours playing, one light went out, suggesting only 1/4 of the charge had been used, and controller charge was about the same suggesting like for like, therefore battery should last one complete controller charge, which is fantastic.
Sticks out of the HTC cradle top but hey, seems secure and seriously longer lasting than the 2 hour charge of the 21W Lucent Trans provided with the Cosmos wireless kit. Ordered another to have one in use and one on charge. At four times the power and nearly half the price, so grateful that a well recognised brand has produced such a cost effective option.
On initial charge two of the four lights were lit. In a QC 3.0 USB charging slot, took four hours for charge to register as complete, therefore expecting an 8 hour charge from zero. If I do run to empty at any point, I’ll update with total time to charge, which from the outset is looks promising.

Not entirely Fast/Dash/Quick Charge

Reviewed in the United Kingdom on June 26, 2019

Verified Purchase

Whatever you call it, it might charge faster for the Samsung and Iphones out there etc, but for the Oneplus atleast the Model 3 and 3T, this does not initiate the "Dash" or Quick charging function. Very disappointed in that.

This may well be down to the fact that the output is lower than that of a Oneplus quick charge. Such a shame really.

Overall, the item is very sleek, quite heavy (what do you expect from a 20k Mah battery) and seems robust.

Very very surprised this didn't have a USB type C input. that certainly was a shock, maybe Anker have a lot of other ports to get rid of.

Charge time to full from flat, you are looking at around 5-6 hours, i like the minimalist look and feel, overall it's quite a good powerbank so far. will update more after a while testing it.

Next model Anker, lets go for USB type C input and output? Inclusive quick charging of all devices. Maybe a minimalist plug top? one that folds up into itself for easy storage while carrying in the provided mesh bag? not everywhere has USB outlets to recharge the unit.
