The Lokithor multi-function Jump Starter (J400) is a portable, emergency jump starter with a bunch of great features to have in the event of an Emergency situation where you find yourself with a dead battery.
The device contains an 8000 mAh battery and weighs about 1 pound. It charges to 100% in less than 20 minutes over USBc fast-charging. In the event of an emergency involving a dead car battery, it's capable of a 2000 AMP peak crank. You can also use it to charge your smartphone or just about any other device over USBa or USBc.
Personally, I prefer the JP400 because it also contains a 150 psi pump to reinflate tires.
You get two plastic alligator heads with a thick, 200°C resistant thermoplastic cable. Even though the plastics are a bit cheap feeling, they can handle the current without being damaged. Naturally, the device comes with air compressor adapters for basketballs, bicycles and blow up dolls.
Definitely a must have for many auto users.
I was able to jump my Jeep SRT's dead battery from cold dead to ALIVE in less than 30 seconds.
