Poor quality
||Posted . Owned for 1 year when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Took this item to the forest for camping. First and foremost, you have to fully charge this item for 48 hours to make it useful. Secondly, the speed of charging my phone was not very fast. Can't recommend.

Worst portable charger
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I have a few portable chargers, and this one is horrible. I can leave my iPhone charging for hours and never make a dent. Meanwhile the battery drains without really charging the phone.

Not worth $60 at all
||Posted . Owned for 8 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.In all honesty, I’ve had this same kind of power bank but it was by nintendo and anker. That one was amazing but I gave it away the same time I bought this piece of junk. Doesn’t even charge with any of my usb-c chargers that I have. I have bad luck with power banks.

Not worth the cost
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Works but doesn’t last as long as my $15 smaller charger. Go with the cheap one, just as good if not better.

Great battery with a trickle charge mode!
|Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.The PowerCore III 20k battery pack looks good and works well! Design I like the look and size of the battery pack. The corners are rounded, the bottom is a smooth. The top has a fine criss-cross engraved pattern. There's one button with four LEDs on it to show the charge level. There are two USB type A ports to charge two devices at a time. It recharges with a USB type C port. It's small enough to fit in a lot of pockets of pants, jackets, or laptop bags and is easy to hold. Features Besides charging devices at a good speed and having what I think is an excellent capacity of 20,000mAH that balances battery life with size and weight well, it also has a trickle charge mode. You can press the power button twice to activate it. Charging devices slower helps the cells last longer in general and is really a good thing thing to do for devices that have a very low battery capacity, like a watch for instance. The trickle charge is easy to activate and it's easy to see when it's active because the first LED is green instead of blue when it's active. To go back to normal/fast charging just press the button again and you will see the LED change to blue.

Anker Powercore sucks.
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Unit charges but does not power the USB port to run things. I bought this May 13th or so this year. Used less than 2 months...Never dropped, frozen, boiled, or exposed to the sun.
