BABAKA Mini 10000mAh Power Bank,Quick Charge 3.0 Portable Charger PD 18W Power Delivery USB C External Battery Pack Compatible with iPhone Samsung Huawei and Tablets-Black

I like this small power bank a lot. It can be charged from 0 with a PD USB C charger and cable in about 80 min. Also it will deliver 2 A or so for fairly quick phone charging. HOWEVER, it states A 5000mAHr battery capacity which is true but that is the capacity at the 3.75V battery voltage. When boosted to 5V to charge, the mAHr capacity is linearly reduced. This is physics. I found a detailed writeup on this somewhere. So realistically this is about a 3500 mAHr capacity at 5 volts. I charged my phone which has a 3800mAHr capacity battery from 15% to 95% when this charger went dead. With other general losses that's about right. Also remember if you use phone while charging it will use some of that 3500mAHr to run the phone and display. So if you really want to charge today's bigger 4500mAHr phone batteries from dead and have some left over you really need a bigger and heavier 10,000mAHr power bank. If you want something smaller to give your dead phone a 75% charge in a pinch this is fine.

1st unit didn't work they sent a replacement quickly

I Kickstarted the pixy mini. I got a notification that the pixy was now on Amazon. I looked in the "maybe check out these similar items" section. There was these dupes of the pixy mini, but one was double battery capacity for HALF the price of the pixy.It works great. I'm going to get another one.It fast charges, but make sure your cord can fast charge too. I got a two pack of 1 foot long fast charge capability USB c cords to go with this battery and the pixy mini.Ok go have fun

Very nice when I travel

I measured 25.81 Wh capacity (I was measuring for the second discharge) which is ~69.8% of the advertised capacity. It’s worth noting that I was charging at a higher wattage (like ~12 W average). All considered, I think this is pretty good, especially since it came covered with a bunch of (cat?) hair and had some light scratches.

One of the most compact chargers around, smaller than the Anker 10,000 mah version. Looks like the old Aukey on Amazon. Able to recharge a Pixel about 2.5x.

The only main main issue I have with this is, when you push the USB port with the included cable (mine only) I can see the other two charging dots , so therefore mine has a broken USB port that still works but doesn't show all my charging indicators.

These compact battery packs are lightweight and store enough juice to charge an iphone a few times. My kids and I took them to Disney and they came in handy to recharge my kids phones while we waited in line. They aren't heavy and fit into even a small pocket.
