Customer Ratings & Reviews

Great power source for long trips and in places you will be without outlets. Last a very long time and charges devices quickly. Be wary though it is rather large. More backpack friendly then wife's purse friendly.

It is convenient, lasts long and charges all my devices.

Yes it is big and heavier than most. There is a very hood reason - the capacity. The best portable charger by far. Can charge three devices at once if needed.

I bought this to use as a back battery/ portable charger while Kayak camping. Its relatively small but will charge my phone, GoPro's, and DSLR batteries while at the camp site or in my dry bag while in the boat. Very happy with my choice in portable charger.

I recently bought this product and it is fantastic! fast charge and keeps my phone running when I either don't have time to plug it in to a wall charger or for quick use on the go to keep a charge.

I work with no outlet available and very little coverage so I burn through my cell phone charge quickly because it is always searching for signals. With this charger I can charge my phone three time and it still has over 50 percent charge left.

I love this thing. Aluminum enclosure that hardly gets warm, solid construction around the charge and USB ports. LCD battery status and doesn’t discharge from sitting. Left this in my glovebox in Vegas summer heat for 4 months and it works perfectly. Will recommend you use an Apple 12 watt iPad charger plug for charging. Using a computer USB port or a small usb phone plug will take well over 12 hours to charge from 20%. Also use a quality cable to charge. The one that comes with it is slow.

Excellent charger for all your needs and can charge multiple items without going dead. Takes long to charge but last a long time without having to charge

worth it! excellent charger. been using it because my car charger broke and I need portable charger to use on my travels. it haven't failed me yet.

This tool is very handy especially when you are travel across country, out fishing, camping and etc. It charge your devices quick and easy.

I like the digital readout indicating the power level. The device is big, so good for traveling etc. Not something you want to carry around though. It charges quickly and has a ton of capacity.

I honestly didn't expect this charger to be this good! It fully charges my battery on my iPhone 6 plus about 6 times! It also charges extremely fast, going from 0-100 in about 1.5 hours!

Have owned several different portable chargers but this is the best I've found so far I like the high-capacity and the hi amperage output for fast charging and it was on sale for a great price.

I would recommend this charger because, i always use my phone and other devices with a high risk of battery going dead, but with this product i don't worry any more!!!!!!

I've never owned a charger like this before so I was a little sceptical. This charged my office a few times and two iPads.... The battery is at 67% still. I love it

I use this all the time. I have an iPhone 6 and can get about 6 complete charges out of the pack before it needs to be recharged. Great product for a great price!

Battery is good. Multiple charges to my gadgets before I have to recharge the battery again. Good for traveling. Does what I need it to do. No complaints here.

The REV USB charger is exactly what I was looking for. I needed a charger for the GoPro camera I have that does not have a replaceable internal battery. This charger has enough power to go through an entire days worth of camera time. And when I am not using it for my camera, I can recharge my iPhone or iPad or all three at the same time. This is everything I wanted in a charging device.

I bought this charger before a week long vacation and I was able to charge my iPhone 5s around 6 times and my GoPro Hero 4 Silver twice. I would definitely recommend getting one. One cool feature that I didn't know would be so useful is the display that shows the percentage of how much battery life is left.

The best thing about this backup battery is being able to see the exact percentage of the remaining energy left.
