Sentey LS-2110 5200mah Rubber Coating Power Bank Charger for Smartphones & Tablets - Black

I bought this for a weekend geocaching event I was going to. I use my phone for navigation instead of a GPS and I needed a power source that would be strong enough to last in the event my phone battery got low on a trail. What I didn't expect was my activity tracker's battery dying in the middle of the day. If I would have had the right cord, this would have been able to charge that too. Oh well. I'll know better for next time.This is very comfortable to handle with the rubber coating especially when you're holding it for an extended period of time. The power bank charges great while you're using your phone. When I needed to charge both my phone and my power bank and only had one charger, I had no problems charging the power bank on my computer plugging it into a USB port.I would definitely suggest this to friends and other geocachers and geo-sports players.

I rate this two stars because it only charges when my phone is unlocked. When my phone goes into sleep mode, the charger must not recognize the device and so it turns off. I have a Samsung Galaxy S5, so perhaps the software on my phone is the issue. Perhaps this model works great, but.... so far it has not charged in sleep mode.

This power bank works perfectly and holds its charge well. It will charge a multiple devices, or one device several times. It's a little big to carry in my small purse, so I will get a lipstick size one to carry in my purse. However, I took this on a trip and it performed very well keeping our devices charged up.

I bought this for a friend and the shipping was fast. I don't know about the quality yet. When my friend got it he said its okay so I believe its working as expected.

Failed within a year as well as the other one I bought. I don't recommend this brand tbh.I was only managed to get a partial refund after contacting their warranty department.

I bought one pair to test them out. Turned around and order 3 more for Christmas gifts! Best $10 and free Prime shipping I'll spend this holiday season!

Only got 1 and half charge for my iPhone 5

We have had this for about 6 months. It worked great until it just stopped working one day and started smoking...
