This thing is great for a cheap jump box. A Jump will take about 20%, but simply plug it into a lighter and BAM its charged (Only comes with USB C cable.) I use this for my motorcycle, but I jumped my 400 twice, and left it on for a moment, and then came across someone who needed a jump, so I let them. It still has 50% On the original from the factory charge. For 20 Bucks, nobody should be without one of these things. Also, it does have an external USB port if you need to use it as a battery pack. I hooked my phone's portable battery pack into this to see if it could charge it and BAM, it would be fine for charging. So, again, this is just a great inexpensive box. Do not be without. Comes with a simple pull tie black carry bag, so you MAY want something more, but it works. Just hook in the connector and click it to your battery post. No buttons to Push Easy to use. Read more

So I got this battery pack to just leave in a car. So I ran a few tests to confirm the battery capacity. The listing claims 20k mAH but it weighs significantly less than the Anker 20k mAH pack I have. So I measured capacity in and out of the battery pack and did not get what they claim. If you look at my pictures the battery pack from empty only took 7200 mAH and it only outputed 4000 mAH. So the claim of 20,000 mAH is false. Also the claim of 5000 amp output is very wrong. 5000 amps at 12 volts would need massive 1 inch cables, this battery pack does not have that. Basically for a cheap jumper pack it may work but I'd recommend spending a bit more for a better pack. Read more
