POWERFUL IS AN UNDERSTATEMENT
GOODNESS ME, this thing packs a huge punch. Started my 4x4 that had a completely kaput battery in a matter of 2 seconds. Not cheap but its an awesome bit of kit

If you get a good one it’s the best out there, keep your warranty handy just in case.
Good strong units, Will jump start anything with high power, recharges fast with the pd65w charger and well built. Only downside is we have had a few fail ( we use them quite often and have about 6 ) sadly 3 have had to be returned due to charging faults but hopefully this will be resolved by the company by better quality charging ports or what ever is responsible for them going wrong. When working they’re great.

Perfect
Bought for work to use over winter for our fleet of vans. Definitely good quality and starts the batteries with no worries. Easy and quick to charge up. Wouldn’t be without it

Expensive but well worth every penny
Absolute beast of a jump pack. Just remember to keep it topped up to prolong its life as per manufacturer's instructions and should last years

Superb jumppack. Did not struggle with a 5.0L diesel engine. I only gave four stars because the supplied cable has USB A to C cable. I think an A to C adaptor should have been included. But this is not reflective of the unit's performance.

Gives independence in winter if difficult to keep battery topped up
Easy to use and effective.
