9000mAh Mini Portable Power Bank with Built-in Cables, Quick Charge External Battery Phone Charger with LCD Display, Compatible with All USB-Powered Devices

I purchased the DS01 unit. I have purchased and used about 5 different portable battery chargers and this is by far the best unit I've had so far. I've seen some concerns in other reviews about the length of time the charge will stay on the battery, especially with the digital display turning on automatically with movement of the unit. The concern is that the battery will run down with the digital display turning on often. I can tell you as an electronic engineer that digital displays like this use negligible power. And I can tell you by experience, having had and using this unit for months, the digital display does not run down the battery. I carry this charger in my cargo pants pocket daily and move and walk a lot. I'm sure that the display is turning on often. I have not recharged this unit for a month and the display still indicates 100%. This tells me that the display does not drain the battery and that the unit retains a charge for a very long time. Some battery chargers run down on their own over time. The battery capacity of this unit is amazing given it's compact size and weight. A group of us went on a field trip taking a tour of a large facility where our cell phones were used for communicating and picture taking. I was the only one with a battery charging unit. It was this unit. Several of our group had their phone batteries run down. I shared and passed around my charger. This unit rapidly charged and put a good charge on three phones and I still had 67% charge left on the unit. The other great thing was that this unit has the Micro USB and lightning cables built in. So it was able to charge iPhones and Android type phones. I highly recommend this unit!

This is a really good size charger, easy and light weight to travel with if you have a small pocketbook. The battery holds up very well but sometimes it gets very hot when charging.

This is an awesome mini portable charger and I absoulty love it.Pros:-Really Good Build-Charging Cables Built in- USB C adapter for newer phones included- Display to show how much energy is left in percent instead of stupid lights- I love the color and sizePredictions:- If taken care of it will last- if cable head breaks that would really suck and wouldn't be fixableNegatives:Charges in Micro USB only witch is annyoing it should be updated to USB COtherwise than all this this portable charger has met and even to a certain extent exceeded my expectations!

Have to give it a shake to charge once in a while is not acceptable to me so I had to return this one and another version of this one that Elephant Story has. But the 8000mAh one seems to work fine.

My portable charger was broken, so I bought this. I love that they have two built-in charging cables for both iphone and android. Also, the size is small and it's pretty light. I can also see the percentage of the batteries. I would definitely buy it again. If there's one thing that they want to improve, I would suggest that they have a protection cover for the portable charger.

This is a really nice charger. We own 3 now. This one I bought for a backpacking trip because I needed something lightweight with the cords already built in. We backpacked for 4 days and this thing kept my phone charged the entire time, without having to recharge it. The best part about it is that it tells you exactly the percentage of battery life left. So never have to worry about it running out unexpectedly. It also charges my phone really quickly.

I wanted to love this portable compact size but in the end returned it. I tested it against other in comparable sizes. Here were my pros cons.Pro:SizeStylishMultiple portsNo cords needed to charge my phone in the go.Cons:You still have to carry a micro usb to charge the units... there thing these days are USB-a or usb-cNo PD (quick charge power delivery) in/out, so slow to charge my stuffIt got hot charging any of my goods.Oh well, I ended up keeping ‘charmest 10,500.

I put this side by side with my usual power bank. Though this one is wider, it is much slimmer. It fits easily in a pocket and contains about 40% more than the one pictured (5200 mah). The built in cables are great (lightning/micro USB) and it comes with a type C adapter which I needed for my Note 9. It also has 2 inputs plus a USB output as well as built in charging cords.
