Customer Ratings & Reviews

This battery is great I charged my note 4 almost 2 times and a ps4 controller once and it is at 49% it feels good and not cheap like my old battery its worth the $80 if you have new smartphones or tablets if your only using it to charge a smart watch the 4000MAh may be more your type

I have used this ever since it came out, totally love it. It has not been like the other chargers which either fail, or dont hold a charge. The only thing that I find weird, there is no website for them. But I will go and get 2 more, this is how dependable they are.

I got mine today 1/2/16 I love it i have 2. i got the small to see how it will work with my iPhone6 plus. it work great. But the battery die fast on it. So got a big one the Battery last a long time I am happy with i, I love it!

If you do the math on mAh per dollar you will find the larger the unit the lower the mAh cost. This unit at 16,000 mAh and about $60 has the lowest cost per mAh at 37.5 cents. Other sizes and other brands run about 50 cents.

I bought this to use when going on vacation in vegas and planned for the wife and i to use. however we had everyone in our group using it and it still had plenty of juice. at least 5 people charged a day

I bought this as a replacement for my portable charger that stopped working. This item is a bit bulkier in size but it does hold a bigger charge and can charge 3 different items at the same time. Additionally, it can charge tablets too. As with my older one, it takes a long time to fully charge the item to 100% so make sure you start charging it well ahead of time before you really need it. The charge does hold well though.

I have the REV charger attached to my Samsung note 4 protected case using a lot of Velcro. I plug 1 wire into the charger and the other into the phone then press the power button. The phone is about the same size as the battery. I love that I can charge my note 4 from 50 % multiple times if I need to. The capacity is so much at 16000mAH that I don't believe the REV has ever seen 40%. I deliver and use my phones GPS so I have to constantly charge if I don't know my way around an area. This REV charger is replacing a charge case I used to use for my Note 4. I would by another one of these REV chargers if I misplace this one. Its got to be 16000 mAH like the one I have or higher though.

Believe it or not ive had this portable battery since 2017 and it just died now in 2023. I wish they were still sold but 10/10.

REV makes excellent chargers and this is no exception. The 16K model is a little bulky for a hip pocket, but excellent for a case or your car. The digital display is good, it will charge your device fast, and they hold up nicely. $50, that's the high end of reasonable; but If it's marked down, grab it by all means.

This thing lasts a long time. I can charge my iPhone 4 x or more before the thing is empty. Make sure you charge it with a high AMP charger. That makes it charge quickly.

I can charge my Galaxy Note 2 at least 4 times off of charge to this battery. It charges at least as fast a the wall charger. By far the biggest bang for the buck.

It charged my phone and my iPad pretty fast, however.

I needed this for a show that I wasn't given any power to charge my devices. The REV - Portable Charger worked exactly as I expected. I would plug my iPhone in at 20% battery and the portable charger only spent 10% of its juice to give me a full charge. Perfect for what I needed it to be!

I'm able to get 4 full charges at 2.4, but the battery pack is definitely heavy.

I got this for our family trip and it was a life saver because we were away from wall chargers for hours. It charged 2 iPhones 2 tablets and s6 back to full. I highly recommend this portable charger!!

I reviewed all portable chargers selling at best buy and these is one of the best capacity in Miliampers that you can found in the store. For me is the best portable charger.

Nice charger, doesn't feel cheap like others I have bought. Also stays cool, I've worried about some others because they get really hot while charging and using.

I charger my iPhone 6s plus from 5% to 100% and it had 94% left!!!!

Charges up my iPhone quickly for more movie taking.

I bought this battery because of its performance... Could charge up to 3 devices at a time to full charge in about 30 minutes. After about month 6, my Samsung cell phone no longer wanted to be charged by anything but the regular charger. My Samsung table wouldn't charge from it either. Guess I have to buy another one.
