Jumper was charged to 95% when it arrived, then charged quickly to 100%. I gave it 3 stars as to longevity being that it just arrived and I haven't had need to use it. It is a nice small size, I'd say it's about 6x4x2. Perfect, for storage in car, motorcycle, etc. Came in it's own soft storage zip up box. It will help keep everything together for future use. I will update as to use, charge holding, and longevity in the future.

I have trouble wrapping my head around how a tiny unit like this has the ability to start a car, but it does. Usually able to use it 3-4 times before having to recharge. Wild!!! Everyone needs one of these in the car.

Once fully charged it will start up immediately this was a great investment so far

First unit didn't work. Sent it back within 30 days. 2nd unit, found difficult as the unit automatically turns off in 15 seconds. Then you must disconnect from battery and unplug cables from jump pack. Took me 6 trys before I could start the vehicle. This is the process I had to go through. assemble jump pack cables to jump pack. push remote unlock button 2 times to turn off aftermarket alarm. then get in vehicle , put key in ignition, wait for vehicle to complete diagnostics. Finally start the vehicle. The automatic turn off feature of the jump pack, which I assume to protect it from bypassing the charging microchip and overcharging the pack through the jump cables. I"m just assuming this. After one use reading was 80%. 4 weeks later needed to use it, wouldn't work= reading said 23% from sitting. Returning unit in favor of Canadian tire branded unit.
