I installed one of these on the current bike. LINK They make them in different styles for different versions of their chargers. I have two older XP-3 Microstart units, bought direct from Antigravity. I also have a Juno Jumper 12v/300A unit from Junopower that I won at a bike event. I didn't use it for a few years, but now am carrying it on the bike since this bike has a small issue when it gets stalled and won't always fire up w/o the jumper box. Very compact and holds a charge a long time. Longer than one of my Antigravity units. (for unknown reasons, one of the XP-3s holds a charge for only about a month or less, the other one seems to last forever.) Both the Junopower and Antigravity units use the same style power connector for the jump cables. Both come with smart jumper alligator clips that are a little bulky to carry, as well as charging cords. The XP-3 also came with a multi-adapter charger pig tail that covered old and new i-phones, USB mini and Garmin GPS plugs.

At this point in time, I am liking the Junopower unit better than the Antigravity unit. Smaller. Both have lights. With the hard wired in starting harness I only carry the Juno Jumper box and charging cord w/110 adapter on the bike. It will charge my Sena, phone and anything else that has a USB plug. I've jump started the bike maybe 5 times and it still reads 4 of 5 bars, w/o topping of the Juno. The V2 costs $99 and the current XP-3, (which will jump start a 4.6L V8 engine), costs $120. Both are quality products, IMHO, that I would buy again. The Antigravity Sport is more comparable to the Juno Jumper V2 that I have, and is also $99 from Antigravity.

While I found the starting harness on Ebay with free shipping that cost me $8 less than ordering direct from Antigravity, I would not order an Antigravity jump box anywhere other than direct from Antigravity or thru a retail outlet that I first verified was an official seller. There have been a lot of fake Antigravity units out there that are not the same quality.

Good info from all on the jump units, but if you opt for just something that charges your small electronics devices, I can throw another vote in favor of the Anker 20k. I've used mine for over a year now and continue to be pleased with the ability to charge multiple devices, multiple times, over multiple days from a relatively small, sleek unit. Will look to the Juno/XP-3 when it disappears or when I plan a solo outing into territory lacking asphalt downhill slopes. ;)

Well I can now review my Earth-X jump box. Un damn believable!! My wife's battery was bone dead an hour ago. I pulled the jumper out of my rear saddlebag compartment, hooked it up and her car instantly started. I am amazed and blown away how such a small device can work so well. I have to admit I was a little nervous because the jumper has been setting and never used since I bought it 11 months ago. Her battery is shot but the jump pack saved the day!!

Thank You Earth-X!!

Yeah, my jumper cable are gonna gather quite a bit of dust. My son was leaving the other day. Started up his car, remembered his forgot something, turned the car off, got what he forgot, and got back in the car. I saw the car sitting there, and the door opened again. I was laughing as he got out of the car, and asked him what he forgot now. He said the car won't start. I couldn't believe it, battery was dead. Grabbed MY lithium box, hooked it up. . . . worked as advertised. MUCH easier than the cables. Still gonna be careful with it so as not to blow me or anything else up.

I had a well used Anti Gravity box hooked to a hydraulic gooseneck trailer foot lift. I was in a bind. It ran fine for about 30 seconds. Then it swole up and smoked it. I've started my 5.0l ford up 10 times in a row with the truck battery disconnected.

That sucks. They do caution you to immediately un-hook the jumper box after starting the vehicle and to not leave it connected and cranking for over 30 seconds. I'm guessing it just couldn't handle the sustained draw from the foot lift. I guess that would have been a time where jumper cables would have done the job and the jumper box didn't.

I had a dying battery on my FZ6 and was carrying the Juno Jumper box on the bike for occasional start needs. I would usually crank ok, but if I stalled it doing a U-turn on a dirt road, it would just click. I had enough of these incidents that I installed a dedicated Anti-Gravity cable to the battery so I could just plug in the jumper box w/o taking anything apart to get to the battery. Worked Awesome! Pull the Juno out, plug in, start the bike, un-plug the Juno and tuck it away and I was off again in nothing flat.

Then I realized that w/o the jumper clips, I could help myself, but not someone else. Had a nice woman with a low/failing battery need a jump and all I could do is wish I had the clips and ride on. She was at a safe place and help was on the way already, but I could have started her up on the spot if I had the jumper clips and saved her a hour or more wait. I've since started carrying the clips again.

EarthX sells a neat setup for hooking up a jump pack. 24 inches of 10 gauge wire with battery hook ups on one end & SAE plug on the other-near the SAE end it separates with the type of plug that plugs right in to jump pack. Very clean connection & you could use the SAE for any accessory. You don’t have to pull any plastic off or anything-could jump start and be gone in minutes. Reassuring when I am way out in the boondocks.
