The Antigravity Microstart XP-1 Kit
But you would probably say I have already a battery pack that can do that... But the Antigravity Microstart XP-1 is also capable to power up your dead battery in the middle of the night in the middle of nowhere on the side of the road.
The Antigravity Microstart XP-1 features three on board power ports: a 19-volt port for laptops/notebooks, a 12-volt standard output for all 12-volt accessories, and a USB 5-volt output for charging or powering any 5-volt USB device..
When we first took a look at the Antigravity Microstart XP-1, we thought to ourselves, how would it be possible that this small device , going to jump-start a motorcycle – the manufacturer even claims that it's capable of jump-starting an old style V8 Chevy. If there were any doubt in our minds we definitely stood corrected after hooking up the mini cables to the terminals of a tired old battery on a 1200cc V-twin we had colledting dust around the workshop. All in all, the Antigravity Microstart XP-1 delivers. And for US$ 160 (without shipping) it's definitely worth having one if you in trouble.
