Customer Ratings & Reviews

Unreal speed while charging multiple devices and keeps it's power FOREVER! We've only had it for a few weeks, and my other one is also 20K mAh but not as fast or long lasting. I also purchased that one for ~$60 while this one was a steal - on sale for a third of the price of my original power bank.

Best purchase I ever made. I recently was a veteran on the Stars and Stripes Honor Flight to Washington DC. They told us charger stations were not really available everywhere. I purchased this and it worked amazing. Even my guardian on the flight couldn't believe how great it worked. Just the right price too!

I gave this as a gift to my sister for Mother's day to use while she's at her part time job because I've attempted to call her and her phone wouldn't have power. She moves around a lot. She loves it. She can easily put it in her pocket and it's light weight. I will probably purchase another one for my son. Great gift!

Did the job. Used it on a backpacking trip. It was a little disconcerting how the lights on the side acted; it wasn't clear that they would turn off after charging it and unplugging it, but they did eventually turn off.

It’s amazing :) I love it I use it everyday would recommend

Charges pretty fast and can almost fully charge my phone twice. I use it in my work truck as I don't trust the power output of vehicles. Its a decent fast charge so its done in about an hour.

This battery pack is super lightweight and it actually charges faster than I had anticipated. I use it a lot because it fits in my purse without taking up too much space and I love that you could use two different kinds of chargers to charge it

The product is satisfactory considering its price point. Given its cost of $9, one shouldn't anticipate high-end quality. While it functioned adequately, it lacked compatibility with newer phones. Nevertheless, I've repurposed it as a backup for my older device.

I purchased this to replace an old portable battery charger that I had. It was no longer functional and could not be used for either of my smart phones. I liked that it charged quickly, even being plugged into my laptop. I can also use it for both my iPhone and Android.

Excellent device with very good charge duration and has helped me on long trips where I am many hours without being able to charge the phone. It is super light and super useful.

With a good cable it charges my phone really fast and helped me while doing deliveries

Store a lot of power. I bought for times like camping trips where Pete is not always available to plug knyo

I bought for my daughter and you can only use the regular usb output to charge your phone the usb-c type is only to charge the battery

This came in handy at the worst time. My car battery died and my phone was about to die. I was stuck in a parking lot with 7% left on my phone battery. Luckily I had this charged the night before and had it in my purse. It fully charged my phone and I was able to call roadside assistance. It definitely saved the day. I had just picked it up 2 days prior. I told my best friend the story. She went out and bought one the same day. It is well worth it and a great price!

I bought this battery as a back up for my phone. It was the first time I had been in a Best Buy in many many years(we do not have one nearby) the great gift that came with this purchase was the excellent Customer Service we received. It was amazing.

Great little charger to give to a kid. My son is always letting his phone die so I pick him one up for Christmas. Small, compact and lightweight now there is no reason not to have a charged phone.

I needed a battery pack for my extended amount of time in the ballpark. This does the job. It's the size of a regular phone. Easy to use - plug n play. So far it's holding up its charge. No complaints.

Works as intended until otherwise. Slim and fits in pockets. Only changes your phone about once and a half. Wish there was type-c to type-c charging instead usb.

This is for the 5,000 mAh model. Reviews for this product seem to mix the batteries of different capacities, making it hard to make apples to apples comparisons. Anyhow, we bought this to have an extra battery on a trip we’ll be taking soon. I went for the lowest capacity version, since I’m trying to keep backpack weight to a minimum. It charged an iPhone 12 Mini from about 15 percent to full in a couple of hours. I’m satisfied.

I think its great! It charges my phone completely! It also holds a charge well, if you leave it for a couple days its battery will be the same as it was! honestly love this powerbank and would buy it again!
