I’ve had one of these for a few years now. It boosted my 12HT over a dozen times without being recharged. Its really light, components are high quality. It’s one of the real things that give me comfort when I shut down miles from anywhere in the bush. I have the XP-10, they didn’t have the Heavy when I bought mine. Tell them you are on IH8MUD, might be worth something

Don’t buy AntiGravity Batteries on Amazon. It’s been known for years they sell the name, not the same product with cheaper components. Mines been through the wars! Buy from manufacturer only.I appreciate all the replies. I had the Anti-Gravity unit another poster mentioned above and I don't recommend it. The battery post clamps are cheap plastic, and mine broke just from bouncing around in my rig for a couple weeks (not hard crazy trail bouncing, either.) Many others on Amazon have reported similar clamp failures just because the materials are weak. YMMV.
