NOCO Compact Lithium Jump Starter
This new product is hard to describe because it has so many different capabilities. Modern lithium cell technology has allowed NOCO to create a jump starter (and many other things) that is about the size of two smart phones stacked together.
It only weighs a pound and is about 7"x3". How much does that jumper box in the garage weigh? 25 Lbs.?
But it packs a 400 Amp punch that will jump start any 12 volt gas or diesel engine.
You can carry it in your glove box!
It will also charge any USB run device, your cell phone, laptop, camera, You name it!
It even has a built in LED flashlight. Super safe, it can't spark or damage electronices, even if hooked up backwards!
