A brilliant life saver
Compact and excellent. When my car had a dodgy intermittent battery this got me out of having to wait ages for assistance and within a couple of minutes gave me the power to start up on several occasions until I could change my battery

Good quality
Haven't had to use it to start the car yet but it's a good small size with a case, made of good quality parts and is great for charging phones/using for laptops etc. Very handy

Useful features
Nest, compact and feels well made. I've not used it to start a car yet but it's good to know it's in the boot should a problem arise.

Very powerful
Excellent piece of equipment, works better than the larger jump packs.

Goos but alarms every time.
Nice jumper pack, comes with enough charge to jump my rav. Gives an alarm every time I use it for over temperature despite my vehicle being well within the units capacity. Annoying more than anything else but works.

Worked first time straight out of the box.
After a very poor experience with a YABER device (don't bother), this item was top rated by What Car. It worked first time straight out of the box. As serendipity would have it, the delivery arrived 20 minutes after the car had broken down with a flat battery. So, with no opportunity to pre-charge, the device was hooked up following the comprehensive instructions and the car started first time. FYI the screen on the device read 81% charge. This is the one to buy - don't waste your money on any other.

Solid piece of kit despite Mickey Mouse design
Very impressed with the sturdiness and functionality. Came 84% charged so was almost ready to use
