Antigravity Micro-Start XP-20-HD Heavy Duty Lithium Jump-Starter Portable Power Supply

When I needed a jump recently, the person who helped me out had an older version of this kit. I was so impressed, I immediately bought this newer bigger version. Very thankful I did, because my car battery died again, this time at 10 o’clock at night in a Boston parking lot. This new starter worked awesome and saved me at least an hour dealing with AAA. worth every penny.It is super easy to use and pretty portable. It’s about twice the size of the older version but it also has a lot more capacity. It needs periodic charging, so I just put a note in my calendar to do it every three months.I clearly need a new car battery, but until then this is essential.It’s probably also pretty useful for camping trips and power outages.Definitely read the entire user manual (which, bonus points, is written in easy to read English). There were lots of warnings about what not to do.Super fan.

Had to use it a couple times due to dead battery in wife's car. Did the job, car started each time. Easy to use, cables are right length.

My car would not start and a friend loaned me this jumper charger which was in her car for months. My car started within seconds! I quickly ordered it and recommended it to others.I’m thrill it keeps its charged so well.

I originally purchased the XP-10 Anti-Gravity Battery and it served me well. However, I recently upgraded to the Micro-Start XP-20 (almost double the amperage) and feel confident I have an 'emergency battery system' to use in my SUV. The XP-20 can be used to 'jump start' almost any vehicle, it has a tactical light, USB recharge outlets and a LCD display to indicate power available level as well as having a 12VDC cigarette lighter socket for power. The battery is very stable and I found I only have to check the power level about every four months and top-if-off to insure its ready for emergencies anytime. Well worth the price and it is a quality emergency device.

The only thing that is missing is the wall charger as part of the accessory that came with the product. I have to buy the wall charger for the XP-20 HD. The previous XP-10 HD came with the wall charger

I had an incident where I jump started another vehicle with my truck and it messed up the factory radio in my vehicle. One of the guys at work has this model and highly recommended it. I bought it and have used it a lot at work for jump starting old equipment. We start the diesel boom lifts and our telehandler. For those not familiar with the significance of starting these, diesel motors are high compression. I would recommend this for anyone who wants to have a charger in their own vehicle for themselves or others. Power it on after hooking it up, you may have to hit bypass until it says start, then start the vehicle. Nice case with a bunch of added accessories for whatever you need to charge that’s not vehicle related.

Works great but if stored in bag near exhaust or engine the battery and case will swell

Best jumper I have owned. The only backdraw is they they keep using the crapiest clamps.
