Excellent and innovative product
Jump starts everything from motorcycles, tractors to v8 powered truck multiple times on a single charge. I started my v8 powered truck with NO battery off this device. Jumped my wife's benz gl550 with ease.
Good for 4 iPhone 5 full charges, will run laptop for 2 hours.
Required 6 hours to recharge from empty via 110v
Delivers 100% as advertised.
Highly recommended

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.

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.

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.

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 )

Great Solution!
I have no electrical access where I garage y bike, so cannot leave it on a trickle charger whenn. Being a motorcycle battery, it does not take too many days before my battery can go flat, and this little tool is a godsend! Hook it up and she starts right up! I can carry this in my saddle bags “just in case”. From what I have seen, the smaller version would probably be fine for a bike. I already know someone else in my boat and have recommended this for a solution. Great Product!

Nice back up for the price
Got this for our long trips on the bikes you never know when battery problems will strike out on the road. We have not had any yet but we have charged our phones and Sena head sets with it and it works great.
