Customer Ratings & Reviews

This back up battery came in very handy during camping. Worked well even with multi charging.

Decided to try this after a recent prolonged power outage. Keeps all our smartphones/tablets charged for days. Great way to keep our devices ready when weather prevents grid power.

It works very well. It is very good to have because it fully charges my phone multiple times without being charged, which is nice since pokemon go drains my battery very very quickly. One bad thing is that it is fairly fragile, as dropping it 3 feet onto the garage floor will crack it. Also it is fairly big which isn't a problem for me but can be a minor inconvenience if you don't have something to carry it in.

I bought this power bank thinking that it would be the answer to my phone charging needs when I am out in the field. While it does provide adequate power back up, it is too bulky to handle and quite heavy too. So I cant just walk around with it in my pocket, it has to be in a backpack. Then it takes a long time to get charged up, time is of essence for me because I work in the field a lot.

My son loves his new device. We use it when we go to show choir competitions and it holds the charge to get him through the complete day.

This is a great charger I would recommend this to all of my friends thanks

This is for those who's looking for solid, rugged, dependable high mah powerbank. It's not your compact and nicer looking one. It gets the job done for me, It can recharge my S7e 3 times. Thumbs up

I've got a few portable power packs and non of them last as long as this one. Really good construction feels really durable. Definitely satisfied with this product.

It was priced very well. And it works very well. The other reviews were correct, it is a little heavy. But, it's perfect for road trips.

Bought for my wife. I didn't read the dimensions and it is a bit bigger than I expected. Not huge but more charges.

This is one hefty battery charger....it claims to be able to charge up to 9 devices on 1 charge to the battery charger. It also comes with a USB to micro-USB ribbon cable. It took a while to charge it up after receiving it but I guess that was necessary in order to charge up to that many devices. Also, RAYOVAC is one of the main leaders in the battery industry... go USA

at the time, 16,000 mah for a portable under $20 was amazing. very durable

The product is very well built, fells solid. It is able to deliver fast enough charges for my iPhone and iPad. Only downside is that when powering an Apple Watch, it sometimes powers itself off leaving the Watch with low battery.

I actually purchased 2 of these for my sons. It provides multiple charges for iPhone and iPad Pro The only negative is that the case cracked under "normal" teenager use.

This power bank is really powerfull and very handy while travelling I used to charge my iphone 7-8 times in a single charge Worth buying

We purchased this this product because of the Mah rating and black friday price online. the product was delivered no problem. so far so good.

keeps my phone alive but gets hot, so I don't know probably not compatible with all phones.

This thing is a strong charger .It works great. Charge it up and you will be ready for many days of charging of phones.

Exactly what I needed to feel safe when out shopping. My phone was always dead when I needed it. Charges quickly

Love to have this when on the go and phone power gets low. only con is that it is heavy and large
