Light, portable batteries for charging laptop, jumping car, USB?

[fuzzybabybunny]

It used to be that you needed to carry a big and heavy lead acid battery for jumping your car, but not it looks like you can get some really, really small and lightweight lithium batteries capable of the same thing.

It dawned on me that a 19V lithium battery really could do just about anything.

19V could jump a car.

19V would be a fine external battery for powering a laptop (my laptop battery is more or less worn out).

19V could obviously charge USB devices.

It could also be recharged via solar, regular outlets, a car inverter, etc.

Does anyone know of any batteries that can do all of this?

I bought this for my mom last year and it has jumped started her 3.0L V6 just fine and she uses it as a portable battery for her phone. It's not going to charge a laptop and it just has USB ports on it. Charging a laptop would need much more juice than something like this. There's tons of these devices on Amazon so take your pick.

Dunno what uses you have in mind, but assuming you want easy human portability, I'd get get two batteries. One lead acid to keep in the car, and one lithium for portability. It's hard to beat lead acid when weight isn't a factor. I use a cheap 17Ah jump box from HarborFreight for work. It would take two of those litium batteries at 4x the price(per two) to do what I need to do.

The Anker & Intociruit only have 400 peak amps.
Might be fine for smaller engines.

For $100, you get a 1000amp rating.

I would just get one with the largest battery capacity, the anker is 10000mah @ 3.8v, no idea what the noco is.

This worked for me when i was in a jam.

Btw here's a good video on that noco unit being disassembled, 1000 amps is actually closer to 250 amps, plus there's a 70 amp relay... yup 70 amps.

Nice find. Seems like it's overpriced by $30 then, since the others are about $70.
