Great insurance.
Batteries don't give you any warning (like slow starting) anymore. Even if you have great road service, a half hour wait in the cold stinks! This has bailed me out a few times. It's even started my lawn tractor. It maintains charge really well so far. I've reduced my times when I check its charge to about quarterly and even then, it's always tested at 100%. If I'm going to leave the vehicle for an extended period, I still "top off" the charge before I leave.

The Micro-Start XP-20 Anti-Gravity Battery should be carried in every vehicle for emergencies.
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.

Impressive.
This thing is sick. It’s very small and light and looks cool and has great features comes with all the charging cables but all that aside it performs crazy good. I jump started my moms 09 c350 benz (H7 group size battery) that had been dead 2 months. Opened the box, jumper came charged at 76%, I connected to the battery and nothing happened at first (battery super dead) which means I got to try the reset feature which is the button next to power. Pressed it once, heard the car chirp to life, started her right up. 5 mins and done. Super easy to use, 2 buttons total on it. Very much worth the money and a huge upgrade from my old huge “briefcase” jump starter.

Very easy to use ! Essential.
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.

Great power box, don't count on it for a diesel though.
I love this box for what it is, we carry it with us all over the place. I bought the HD for my Cummins Ram, just in case. My only complaint, when I needed it for the truck, it didn't even TRY to start it. 100% charge and not the smallest turn of the crank. That being said, it is great for everything else, tractor, cars, boats, we do use it regularly.

Just an expensive phone charger.
This battery worked well for 4 months and after that the battery wouldn’t recognize the cables when attached to my car battery. After communicating with the company, they said they didn’t have any replacement cables but could fill out a form send the battery back and they would replace it. I sent it in over 30 days ago and have heard nothing back. Now I’m out the money I spent on the battery as well as the phone charger it turned out to be.
