AstroAI S8 Pro Car Battery Booster Jump Starter Power Pack & Portable Car Jump Starter Power Bank for 12V Vehicles (9.0L Petrol / 7.0L Diesel), with Smart Jumper & LED Torch

I bought this as a generator at work didn't start when there was a power cut. (Battery wouldn't hold it's charge). Anyway ordered it and it came the next day..I took it to work the next day and hooked it up to the generator. Started first time, fantastic piece of kit to have, and keep it in my car now. You don't have to rely on anyone with this. As you do with jump leads. (another vehicle needed). Also like the ports on it to charge phones etc, and a torch. Glad I bought it, good price and as long as you keep it charged up you shouldn't get stranded anywhere.. Battery in generator replaced now. Happy days.

Great product. Connected up to car battery and left it for a minute to get some power in the battery, turned the key and it started up straight away. Highly recommend.

Looks reasonablely well made it was reduced to £39.99 so thought it might be worth a punt as I've just purchased a hybrid car and reading reviews they have to start up in electric mode so if your battery goes flat you can plug this in to get you going it's small enough to fit in glove box and leave it in so it available in an emergency it does recommend you check the charge every three months for state of charge haven't luckily had to use it yet so watch this space.

Ive had this for a couple of months and today I got to use it, twice in the space of an hour! first off to start my 3.6 litre 911 and then onto my 2 litre diesel transporter. worked perfect for both. still showing 75% charge left. I was looking at a more expensive one but happy I chose this one!

Superb bit of kit , only ever used this one so cannot compare , came in handy already as my sons 330ci bmw had a flat battery , connected this within seconds it started

Arrived with 50% charge but only took approx 1 hour to get it to100%. Connected to my car battery which was not completely flat but had insufficient power to start the car. Started the car no problem. Would recommend

Bought this as my battery was going flat with a fault and I could not get into a garage for a few weeks, this has been a life saver, starts the car ford focus first time, very easy to use and great to have a flash light built in. I would definitely recommend this product to friends.

Some what disappointed. Great reviews , know people who have this model. But on this occasions which happens! I got a faulty one.
