Cross Reference & Compatibility
Customer Reviews
I have a parasitic electrical battery brain that so far no one has been able to trace to any particular source, so a good reliable jumpstarter is an essential for me. I ordered one from BatteryMart, and while shipping to Alaska significantly added to the total cost, BatteryMart was upfront on the prices, wouldn't place the order until I approved it, and then shipped right away. It was at my door within a week. BatteryMart was the only company who would even ship this type of lithium battery to Alaska, and I so appreciate that fact. It was even fully charged when it arrived; I also ordered the case for it (it is great as well!).
Excellent product exactly as advertised, will be ordering additional units soon for HolidayGifts to Family and Friends
Works great. Wish I had purchased one years ago
Battery was what I ordered and was a perfect fit for my generator.
I gave it four stars because I haven't had a chance to use it, yet. But, it looks like it's incredibly easy to connect to the battery and turn on. It has really good features on it as well; like the flashlight which helps you see when it is dark out, and the usb port which is handy for charging phone if necessary. I will submit another review once I have had the chance to actually use it.
I purchased one of these for each or our vehicles. A few weeks ago my battery died and a motorist pulled a NOCO GB40 and jump started my car. I saw the product as a valuable asset. Have already used one of them. Don't leave home without a booster unit.
The jump pack at work was broken and I had to get my fleet out of the yard. I grabbed this out of the truck of my car and on the first turn the truck started.
