JONKUU Small Portable Chargers 10000mAh, Power Bank USB C Quick Charge 3.0 External Battery Packs LCD Display for iPhone iPad Huawei Samsung Android Nintendo Switch Tablets

I give this 5 stars because I wanted a nice battery pack that supports QC 3.0. So it is exactly what I wanted. I will say, mine has a button on it that does not do anything, so if you are looking for a battery pack with a functional button, this might not be the one for you but I don't care about the button so no stars removed. Also, even after going through the recommended calibration process, the digital display is still not correct - it will hit 0% and keep charging for a while. I also don't care about that feature so no stars removed. Either a battery pack is full, empty or somewhere in the middle and the exact percentage doesn't matter to me. I'd recommend this battery.

Small and compact, excellent power delivery output, digital capacity gauge eliminates guesswork and doubt.Initial quality seems on par with more expensive brands like Aukey and Ravpower.One of the best bang for your buck power banks I've used.

This external battery pack is a great value for the money. The pack has no trouble powering a TS80 soldering iron in either 9v or 12v mode. The LCD display is useful, clear and pleasant to read. Unfortunately, the battery inside the case is not secured and rattles around freely and noisily. I ordered a replacement battery pack, and it also rattled in the same way. That doesn't inspire confidence in the pack's ability to be an on-the-go regular for me, so I'll end up using it around the house instead.

I typically buy all the bigger name brand packs but decided to give this one a try. As an engineer I'm very selective about what powers my devices and with knowledge of how easy it is to make claims on these I approached with caution.After getting the pack and using it for while it performed exactly as advertised. I even went as far as using meters to test its ability to deliver power and also rated capacity. All checks out nicely. I'd buy another or something else from this brand.

I liked the first one I got so much, I ordered two more. The metal case looks and feels great. While I am not one to complain or dismiss a quality power pack over a cheap feeling case, this one will be hard for them to complain about. The digital readout is also extremely useful. I use these for cell phones, pads, lighting when the power goes out & mini fans when it's not quite hot enough for AC.

Great little power bank - lots of power to charge my Moto G Power 2-3 times. The digital readout is much better than just having "dots" to let you know remaining power levels.

I needed a smaller power bank with QC3.0. This fits the bill perfectly. I love the digital capacity display, but i did "calibrate" it as the instructions stated. A great buy.

I purchased this to go in a small pocket provided on a heating pad. Altho it seemed too big and heavy for the pocket at 1st, it actually fits nice and snug without adding much weight.The package came with instructions to charge up/down fully 3 x's at 1st to ensure best battery life.Before using as intended for regular on/off use, I'll charge 100% and use to charge devices while not turning the battery on/off, running it down fully and repeating for 3 cycles before using it with the heating pad when it will then be turned on/off frequently before running the battery down.I'll then come back and edit my review to advise how this battery does works after all.
