I found this charger to be incredibly useful, for its price

Reviewed in the United States on April 28, 2018

Verified Purchase

This is my second Romoss Portable Charger. I found this charger to be incredibly useful, for its price. This power bank is very well-built, sleek design with 2 USB Ports. Best part is: I can recharge this portable charger using my own iPhone cable, that way I don't need to keep carrying a Micro USB charger to recharge it. Having 2 USB Inputs and 2 USB Outputs are super convenient. Something I’ve loved about this power bank is: 10000 mAh capacity. It’s light-weighted in comparison to other 10000 mAh Power Banks and has charged my iPhone really fast. Also noticed that it holds power very well, so good for outdoors and trips. Highly recommend!

Worth every cent

Reviewed in the United States on March 9, 2017

From my first test of the ROMOSS A10 and my iPad Pro 256 GB with the battery level at 90%. I wanted to see if while I watched a 1 hour video stored on my device if it would charge the battery in the iPad back to 100%. It dropped to 88% in an hr. of playback which I guess isn’t bad. All the while the ROMOSS kept 4 lights illumined so looks like I can go quite a while on a charge. Then with the iPad still plugged in I also connected my iPhone 7 Plus with 256 GB. It finally dropped the A10 from 4 to 3 lights after about 10 minutes. But the iPhone went from a 92% charge to 100% in just over half an hour all the while the iPad only dropped one more percent. I gave it five stars for the price and size it’s going to be a handy backup for my phones and other devices. Yes, I would recommend it to a friend. BTW I made sure in both the iPad and iPhone I closed out apps so there was nothing running in the back round before I connected them to the battery.

A Quality Charger

Reviewed in the United States on March 3, 2017

Verified Purchase

Bought this item for my IPhone 7. It was a little heavier than I expected, but it is a high capacity charger. It works very well. My IPhone 7 was down to 23% battery life when I plugged it into the Power Bank. In less than two hours, I was up to 100% charge. The Power Bank still has enough power to charge my IPhone several more times. This is important to me since I plan my music on it while I work in my garden that is in the country where there is no electricity. I had been looking for a charger for a while, but I wanted it to be safe for my new phone. I am glad I found this item on Amazon.

Charges fast

Reviewed in the United States on October 6, 2017

I've been looking for a portable charger for my phone that didn't feel like I was carrying a brick inside my bag. Although some people have said this is bulky it is not for me considering what I had before. It charged my phone pretty quick, too, which is exactly what I hoped it would do. I haven't tried charging two devices at a time but after fully charging my phone it was also able to charge my boyfriend's phone afterwards. It's heavier than some portable chargers but like I said, it functions the way it's supposed to and met my expectations.

Great battery life

This battery is impressive! I ordered it because I had a 20 hour drive for vacation. It has charged my boyfriends phone once, and my phone twice, & still has juice in it. Way better than my last one. The only downside is it is very heavy.

This is the 3rd one i have tried. The first 2 would not hold a charge. This one is great. Fast charge and keeps my devices going. Good for 5-6 hours at least maintaining a charge at whatever level I was at when I connected the charger.

Perfect for iPhone

Reviewed in the United States on July 7, 2017

Verified Purchase

I just received this. Looks very good.
Pros:
1. It could be used with only one cable for iPhones, because it has two inputs. Not just micro USB as most other batteries.
2. Small.
3. 10K mAh
Cons:
1. Heavy. I have another one which is much lighter and a little thinner than this.
2. The maximum output current is 2.1A, comparing to my other one which is 2.4A.

If you use a micro USB then I would not recommend this one. There are better batteries.
But for iPhone-s this one is perfect.
