WOLFBOX Jump Starter Power Pack, 3000A Car Battery Booster for 12V Vehicle with 65W Quick Charge, Car Jump Starter Power Bank for 8L Gas 6L Diesel Engine with LED Light, Jumper Cables

Absolutely fabulous device, well worth having, has been used several times and worked perfectly every time. Very easy to use and the battery is long lasting too.

I was a little dubious about such a small device starting a marine diesel engine, but research on the net persuaded me. With my boat on a swinging mooring and a dead engine battery, I ordered one for delivery the following day. It arrived on time, charged to 75%. Using the recommended 63A charger, it quickly charged to 100%. I took it out to the boat and connected it, where it performed brilliantly. The engine turned over and then burst into life. Problem solved. The case that comes with the unit is a nice touch; good quality and keeping everyting, including the (not included) charger, together. THe higher capacity charger may be a good investment if you are in a hurry. I plugged in and saw the display count from 75% to 76%, 77%, 78% in front of me. If you're not in a rush, your phone carger might do but if you're racing the tide, worth the extra money.

Very satisfied, fast charge and powerful

This is a great little device. Charged from 74% (as delivered) to 100% in 20 mins via a standard charger. Very easy to use with clear instructions. It took 6% of the charge to start a 2ltr diesel engine.

Brilliant, easy, straightforward and compact in its own bag

Does exactly what it says it will do. Started my Juke from a dead flat battery on one turn over. I've tried others that took 2-3 turns but this wolfbox is amazing. I got the charger as well and it charges so fast it was 100% in no time. Comes with it's own storage bag which holds the charger plug easily with space to spare. Easily recommend this starter pack.

Excellent quality, great value

Product worked fine for the 3 or 4 times I needed it. Then 6 months after I purchased it the charger died and was useless. I’m now in the process of finding out where I stand on warranty. On contacting the supplier, I’m pleased to say a replacement was sent to me promptly. The faulty unit was returned for evaluation. So I am now satisfied with the service log WolfBox.
