Powerful
Good size, good functionality.Had to use it before I had a chance to charge it. Worked flawlessly.The self check on whether it's connected correctly is a great feature.Seems to be well built, but can't comment on how long it will last, needs a lot of use over time for that.

Since purchasing i have used this product multiple times on work vans and helping friends. Never let me down, can do multiple starts on a single battery life. Very easy to use.

Misleading specification
It's working fine, it's very light and compact. I've put 3 stars because the specification is misleading and Amazon shouldn't allow it.It has 4x 3.7v batteries in series obviously to generate over 12vEach battery has a capacity of 6000mhaWhen you connect in series the capacity remains the same it doesn't accumulate.So the capacity is 6000mha and not 24000mha as claimed

Not up to the task!
I purchased this unit to start my Volvo 2.5 petrol engine and was very dissapointed that it would not turn the engine over. Considering the listing states it will start petrols 7L and above.Also does not even come with a case instead you get a small bag which is very inadequateReturned to seller for refund
