Added bonus has USB chargers for devices so it can be used as additional battery for my ipad and a bright little LED torch too. My only very tiny criticism would be lack of carry/storage case, but i knew there wasn't one when i bought it! This is great already recommended to a couple of friends who have purchased already :)

Bought the other day and it started my car first time with no issues. I’m amazed just how small this is in comparison to one I’ve used previously. Things have definitely come a long way. Like the built in torch and fact you can use it to charge other devices. It’s an essential necessity in my opinion to any car. I can now drive with the knowledge my car is not going to stop working in the middle of the night with no one around. Nice and easy. Simply connect the black cable to negative and the res to positive of your car battery and start the engine. Once the car starts, just disconnect. It really does not get simpler,peace of mind. Not expensive. Easy to use. Compact and light. The only thing you need to remember is to charge it every three months so it lasts longer. Especially because batteries don’t like the cold weather so it depletes their longetivity.God knows where we are all going to stand with electric cars when at least sixty percent of the car value is the battery but that’s another story. If the battery dies I guess you need to buy another car. They certainly are not replaceable and even if the manufacturer can replace it, I doubt it will be worth your while.Highly recommended device. I do agree with other reviews though that a pouch to keep it inside would have been excellent but that’s minor. I have loads of pouches lying around I can use and for this amount of money I can’t complain.Rest assured this battery can charge a battery up to 6 litres so anything below that is fine. My car is just 1.2.,

It has started my motorcycle twice now, without being re charged. So it did what I purchased it for. as others have commented the battery leads could do with being longer. But very compact and very easy to use.

I bought the UTRAI Jump Starter in March this year. I read the instructions, watched the video, charged the jump starter, then put it under the driver’s seat in my car and almost forgot about it. That is, until recently when my sister-in-law asked if I could take her to a dental appointment. I got in the car, turned the ignition key and …. nothing! The engine didn’t even try to turn over. I was in a bit of a panic as, if I couldn’t start my car, my sister-in-law would miss her appointment.I lifted the bonnet, then rushed to find the jump starter. It was so easy to attach it to the car battery terminals. I hurried back to the driver’s seat and turned the ignition key and …. vroom! The car started immediately. All this in less than 3 minutes from realising that the car battery was flat.I am so grateful to Utrai for developing such a clever piece of kit. So small and yet so powerful. And you don’t need another car to jump start your car. The Utrai can also charge your phone and it has a powerful torch built in. I love it!

Don't drive daily. AA rescue service had a word with me about calling them out so often to start the car. So researched Bolo and got this. First one got stolen recently - hot day, passenger-side window left open, and this item was behind the seat in a bag together with the satnav, but would you believe it, they found it and took it and are probably thanking their lucky stars to have found such a useful item. So I ordered another one. Interestly I found a similar device in Lidl but it was hopeless. I think it was East European or Russian-made - lots of reviews in Russian. This one is the best. It is very dependable and has not let me down once. Say we have a hospitabl appointment and the car won't start. Do I panic? No, I have my little genius device. Once, I did a short drive to the High St and when I came back the car wouldn't start. A young chap seeing my plight did a prompt u-turn and pulled up. By the time hid had parked bonnet to bonnet with me, I had had my discrete device out and already started the car. He wasn't impressed at being denied the chance of Knight-in-Shining-Armour-hood.
