Customer Reviews
Absolute lifesaver. My car wouldn't start on a freezing Tuesday morning before the school run. Hooked this portable car jump starter up, and the engine fired instantly. So much easier than waiting for the RAC.
I bought this primarily as a battery charger for motorcycle battery maintenance over winter. The trickle charge function is brilliant, and it's small enough to take with me on long tours just in case.
As someone who knows nothing about cars, the safety features on this booster car battery pack gave me huge confidence. The green light told me it was safe, no sparks, no stress. Highly recommended.
Fantastic bit of kit. Started my 2.0L diesel van without a hitch. Dropped one star because the cables are slightly short, which makes positioning the box a bit awkward under my specific bonnet, but it works flawlessly.
I was looking at NOCO units, but this offers so much more value. Having a battery smart charger 12v and a jump starter in one compact case for the boot is perfect. The built-in LED torch is incredibly bright too.
Used it twice already on my wife's older SUV. Holds its charge in the boot for months. It's a very reliable 12v lead acid battery charger when plugged into the mains as well.
Brilliant product. I leave it hooked up to my classic car as a battery car maintainer during the week, and throw it in my daily driver for long trips. Exceptional build quality.
