Antigravity Batteries

Antigravity Batteries built its reputation in motorsports — particularly road racing, motorcycles, and powersports — where low weight and high cold-cranking output matter more than cost. The brand claims to have introduced the first lithium mini jump starter (the original Micro-Start) and has since expanded the XP line into a full portable power supply platform with USB-C Power Delivery and large-format digital displays.

Products are designed and engineered in the US and are sold through the brand's direct website, specialty motorsports retailers, and Amazon. Warranty is handled directly by the brand, which has a positive reputation for responsiveness based on community forum reports.
