Great Batt for both my bikes I purchased this product for my Adv Touring bike (nobody wants to be stranded in the wilderness with a bike that won't start) but take it on the Harley as well! A little added insurance. Not to mention the added bonus as well of charging cell phones and other misc. electronics. Awesome value and well made. I even used it to power some LED lights I had.

Learn from my store-bought experience. First let me say this is a well made and equipped unit. And if your looking for this kind of thing then you will be good. My issue was simply that I bought this to charge my Sena 10s headset and iPhone 6 while camping. The jump start option was an added benefit. I previously purchased an iBattz charger and ended up giving it to my daughter because the unit had a auto off feature then when connected to my Sena headset would turn itself off because the headset did not draw enough current while charging to stay on. I talked with both revzilla and antigravity before buying this and they assured me this unit would charge and stay on until the headset was charged. Not the case. So my main issue was that the tech people at Revzilla and the the tech at antigravity themselves did not know what they were talking about. So take my advice. If you are going to charge a Sena headset, find a charger that DOES NOT HAVE AN AUTO-OFF feature. It charged the iPhone just fine. And with that said some research will reveal that you can find this same unit with another companies sticker on it for about 1/2 of what antigravity charges. Revzilla still rocks on customer service and their return policy ( I hope ) June 24, 2016
I have traveled to Europe, started my wife's car and jump started my friends bike and this battery backup has lived up to its promise Great product would highly recommend this just bough my second one for my in law. May 24, 2016
Amazing light and small This thing is amazing. I left my heated grips on after i had commuted to work one day. Which it was sitting for 10 hours like that while i was working and drained the whole battery. With this I had the bike up and running again in five minutes. it comes with everything you need and a little bag to store it all in. at this point I've had it for a month and I've charged my phone 6 times and jumped the bike once and it still has 3 out of 4 bars for battery life. I would recommend this to anyone who lives in a major city where calling some one to get a jump costs 65 plus dollars for 2 minutes of work. I would also suggest getting the wire harness that is sold separately cause you don't even have to open the tail and seat to get to the battery. You just plug it in the the harness and jump from there. March 8, 2016
Must Have for Wandering Off The Beaten Path I purchased this for a dual-sport trip to Utah and Northern Arizona. None of the bikes we took had kick-starters, and we traveled far, far away from civilization and over some pretty challenging terrain. This light weight but powerful device insured that we would be able to recover from a dead battery on a bike or on the tow vehicle; and it provided backup power for smart phones for off-line maps and GPS. In my opinion, this is a really economical and very important safety device. Also, after the trip, it came in really handy on a couple of occasions starting up a lawn tractor with a dead battery. This device is kept in my wife's car and I plan to get another one for my pickup. I think everyone should have one. December 14, 2015
Great Product!! I was out on an ATV ride with 6 Razr's and 4 ATV'S. well need less to say one of the Rzr's would not start so I pulled out my Micro Start and jumped the rzr and it started right up . I had about 5 friends take pictures of the micro start and they will be ordering their own. That is real world application. September 15, 2015
Very cool Jump started several bikes and trucks with this little unit. Ver convienent. August 27, 2015
Awesome product - tremendous peace of mind I just ordered this product last week. I had heard great things about it, and I recently transported a Vespa to my summer home where it will stay since I upgraded to a Honda CB500X a few years ago. Vespas are notorious for battery issues and I've had my share over the years. I also wanted backup for longer road trips on my Honda or just in general if the cars have an issue. The day I received my X3 I had a reason to use it as my Porsche Boxster was in the garage with a dead battery. The product is extremelly portable - its light and the case holds all the parts necessary to charge my devices or jump start a vehicle. I charged it (about 2 hours) and then hooked it up to the Porsche and hit the power button. Immediately I heard the radio come on and a few seconds later I had the car started on the first attempt. The Boxster has an interesting issue when it dies, and that is that you can't get at the battery because the hood lock won't open manually. So you have to jump the hood first, which is a really tight little plug in the fuse box down by the clutch pedal. This is where having a small device with a light already attached really pays dividends. Short summary is that I love the product - its light and easy to transport, and I'll be using it for any distance travel - car or motorcycle. I may have to get a second to leave out at my summer home. I highly recommend this product. August 13, 2015
