Car Battery Jump Starter 6000A Jump Box (10.0L Gas/9.0L Diesel) Portable Car Jump Starter Pack, 12V Battery Jumper Starter Portable, Fast Charge, 160W DC, 4-Mode Lights

There are larger version from this brand that hold a better charge but this thing is solid! It jumped my classic truck right away and only took about 15% from the battery. No more asking people for a jump. Get this unit!

works well it started my dodge diesel very easy susprised how good it worked

Excellent quality and ease of use. Very happy with purchase.

All I have to say is that this item work as advertised. I bought it to start my vehicle because it was having problems cranking during the winter. Once charged it was able to provide cranking power to my Honda Accord. The only negative is that it appears to lose charge quickly after it is turned on and put in use. you may be able to get 4-5 jumps from a single charge, if you turn it off after using it. The good thing is that you can charge it using the adapter for your cigarette lighter. Note - make sure you get a charger that has sufficient charging power (AMPS) for your type of battery - do your research before you buy.

A very practical battery-powered starter power supply！

Reliable Easy to use Get this one

Chose this jump starter for it’s no-nosense design, and large digital display. It is solidly constructed with no hint of bending or flexing. The USC-C port is for input only and no Power Delivery (PD) for faster charging. Since it will be rarely used as a power bank and will be topped off periodically, considered this to be a minor inconvenience. All the electronics (including diagnostics) are contained in the main unit, with no clumsy attachment on the cables. The downside to this is there is no voltage meter, but seems be a fair tradeoff. Includes a “boost” function, which may work in the event a battery is completely dead. Some of the jump starters I looked at did not include this feature, even more expensive ones. The included case is nice, the foam padding completely encloses the top, bottom, and sides of the starter - a nice touch. Overall, quite satisfied with is purchase.

Okay to charge me cell phone. Tried many times to use on cars and pressed the bottom button and it went down a tiny bit in percentage and clicked and stopped. Tried car to no avail. Went and tried again a few times but same thing. I think it is supposed to load power into the car battery if what I read is correct. I tried it by turning it on and then try and start the car. Nope. Then pushed on the bottom one and tried the car. Nope. So I have a charger for my phone. I give up. And yes the unit I charge to 100%.
