Worked great rapidly charging in a few hours. After charging, it gave multiple recharges to my Iphone while using a GPS app on camping trips. After some use it had a problem recharging but after contacting Techsmarter, they corrected the problem.

High quality, high capacity, and fast-chargjng battery. It works amazingly well.

Had in issue with the power bank not holding a charge anymore. it was still inside the one year warranty and the company sent me a new one free of charge

The first product they sent me turned out to be a bit faulty, as the USB ports stopped working after a few uses. When it did work, the battery life and speed was very good. After contacting the company about the issue, I was taken care of. Hopefully the replacement works, as this is a good product!

Just a quick note, I normally take the extra time to fully discharge and charge a battery yo test its full capacity. I have not with this battery but I can say it easily keeps pace with a 28,600 mAh battery I have from a big named competitor and in the number of ports and charge power, I put the other one in the storage drawer. This is right now and will remain my every day carry. I definitely give it 4 to 5 stars, and though the thickness is a little bigger than other similar products it allows for the length to be shorter. LED light is solid in brightness, and pulls next to no energy. Was WELL used during the power outages in the south due to weather where we lost power for nearly 4 days continuous. Solid all the way around and I highly reccomend it for any indoor or even outdoor use EXCEPT DIRECT SUN. And that not is because nothing lithium work well in excessive heat. Just FYI. Buy and enjoy responsibly. It is worth the price.

I had an issue with battery powering. Contacted customer service via the chat. I was just thinking it was an operator error issue and just wanted an instructional booklet. Customer Service Rep had me send a video of the issue. Immediately Identified the issue and without even asking me another question sent out a replacement.I ordered a second device just because of the Customer services...Thank you again for such an amazing experience.

Stopped re-charging after a month of use. Apparently the return policy is only 30-days, so buyer beware. You could be stuck with a lemon. Note, I used this charger very lightly during it's 4 weeks of use. It went on a couple of work trips with me, but was never exposed to anything that would be suspect in causing it to malfunction.Anyone have alternative recommendations? I'm looking for a charger that's durable, but also can charge my phone at least 3+ times without having to recharge the charger.

Long lasting power, versatile, and durable.
