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.

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.

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

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.

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.

My battery on the Sena 10C does not last long so this should help charge it on longer trips.
Mike A on Mar 24, 2016
A buddy of mine has this for his bike. The only negative feedback is the alligator clips are wide and stubby so they may not physically connect to your battery.

I borrowed one from a shop, I had my doubts due to size but the motorcycle started right up. After seeing what this charger can do, charge anything from a phone to a small truck, I figured this is definitely something to keep in my backpack. Worth the purchase, can't put a price on not being stranded.

I noticed this unit has a auto power off feature. I gave my last battery pack away to my daughter because my Sena 10s did not draw enough current to keep it on. Will I have this same problem with this one or will it charge a Sena headset?
Onesaintsfan112 on Jun 20, 2016
BEST ANSWER: The new XP-3 models have 2 outputs : a 1A and a 2A. If using the new model and the 1A outlet, it should be sufficient to keep the AntiGravity on until the Sena is charged.

Can someone from Revzilla confirm if these are the new models, or the older ones as shown in the pics?
Are there 2 output usb's on the models now being sold by Revzilla?
can this battery be used to power heated gear (jacket/gloves) while unplugged from motorcycle?
A shopper on Nov 16, 2015
BEST ANSWER: Your question is somewhat "strange", and interesting at the same time....
Strange, because this battery is designed to give you electrical starting power, in case of main battery problem; I do not see the "figure" to be constantly plugged to it, unless it is an emergency....

On the other hsnd, I have not tried to use it in anything else, that is not charging different electronic devices (phone, Ipad, etc). But I can not imagine any problem using it as a power source for what you are mentioning.

Good luck with the challenge (if you decide to buy it), and let us know how it went.
how long does the xp10 hold a charge before needing to be recharged ?
A shopper on Aug 9, 2015
BEST ANSWER: I have had the battery sit for over a month and it still held almost a full charge.
It generally takes under a full hour to bring to a full charge when its about 50% charged. When its 50% charged it starts my motorcycle multiple times and it stays charged after the jump.
I find this tool along with a tire repair kit to be essential tool kit.

It also servers as a laptop, and phone charger. Depending on what model you get, you can get with multiple power adapters to plug in your phones, GPS and laptops to charge them, proves very useful off the bike.
Do any of these small lithium battery jumpers, not just the Micro Start, come with the plug to enable you to jump using the battery tender plug so as not to have to actually use the jumper clamps directly to the battery? I hVent seen any that do which is why I ask. Is there an issue with the amps using the battery tender plugs?
A shopper on Nov 28, 2015
BEST ANSWER: I tried it. Not a good idea. My battery tender has a fuse in-line. It blew the fuse. I do not know what will happen if you try it with a tender without a fuse. I use my MicroStart as an emergency backup only. I now only hook it to the battery so I can get home and then address any issues with the battery or electrical system directly.
Can this be used to trickle charge or just jump start?
William P on Jul 7, 2016
BEST ANSWER: You can buy a special pigtail from Antigravity that hooks directly to your battery. One end connects to the battery (obviously), while the other end has the special proprietary connector that connects to the Antigravity Micro Start. HOWEVER, there is a special plug that adapts from that proprietary (blue) plug to a standard SAE cable. SO, you can leave this adaptor on and use the pigtail for power, charging devices, etc. If you have to jump it, just remove the adaptor plug, plug the blue plug left on the pigtail into the Micro Start and jump it.
I have these pigtails/connectors on both of my bikes, and use them all the time. Very convenient!
