portable car jump starter, Power-77, black with 19800 mAh, 12 volt, 800 A peak amp, car battery booster, jump starter and portable power bank, start vehicles with a cylinder capacity of up to 6.0 litres petrol and 3.0 litres diesel, up to 40times

A handy gadget to keep in car and it can charge other electronics items as well. Mine came with a UK plug and it worked the first time when husband had to jump start his car. I was a little worry after reading the other review and the pictures, so I paid extra attention when it was charging. The power bank doesn't really get hot when it was on charge so it eases my worry.

This looks good quality. Beware though - the power supply has a euro plug - so you will need to convert for use in UK sockets - took off one star for this. You can use the adaptor that you use for your shaver. Haven't used it yet - fingers crossed may never have to use it - but it's there in an emergency.

I love the feeling of this bit of kit, feels great in the hand, one major problem was, it would not charge to 100%, no good to me, it’s clearly a one off issue, because everything else is brilliant one minor problem, it has an EU plug on the charger cable, and selling it to the UK market is a pain in the arse if you have not got an adapter.

Looks and feels like a quality product just waiting for the battery to go flat so I can use the jump starter 😀

If I could give less stars then I most certainly would. I never had the opportunity to actually use this product as it exploded while on charge and caused a serious fire (luckily I was home to put it out). I have been speaking with the suppliers for the last 4 weeks who are nothing more than a waste of space. They will not admit there is a fault and have all but washed their hands of the situation. If you feel like putting your family at risk then go ahead and purchase this item.

So far - very good!

Received the Guluman 800A today. The reason for buying it was that two of my cars sat on the drive way with the batteries discharged. It came in very decent packaging with all the adapters needed for it to work. The unit itself had just one green light(there are four in total. Each blue light coincides to 25% charge of the unit) was perfectly fine in starting my Petrol 2.5 Nissan X trail in no time, when I tried to start my 2.4 Diesel Volvo XC 90 it did not start. I had to charge the main unit for around 2 hrs to get the Volvo jump started it started the car in no time once it had the sufficient power. My overall first experience of the product has been great. I definitely would recommend the product, though it has a limited warranty of 6 months and the overall life as stated in their instruction book of 3-5 Years, had the warranty been a year or so I would have given them a five star. Overall a nice product.

I'm using for a car with 3l and I used 3 times and the battery is still full. Is better them what I thought. I highly recommend.
