Excellent product that arrived on time and very well packaged.On opening the Car Jump starter has it's own carrying case which is perfect and keeps it compact.The company also offers a 3 year extended guarantee so no requirement to purchase a 3rd party policy on checkout.It comes 88% charged so it can be used out of the box.Excellent product all round.

Excellent product.Safe ...Easy to use.....Value for money.Would highly recommend.

As my battery was flat, bought this for jump start, very straight forward,no issues ,I use it three times it's still have seventifive percent charge left.Can be used for light or charging other devices.size is not to big.useful battery power pack.

I purchased this device after letting my battery run flat one evening in a car park.I asked the driver of a van that parked nearby if he had some jump leads that i could borrow and he fetched this device from Flylink tech.It started the car immediately, very impressive.He explained that he was a mobile mechanic and had been using it daily for the last few months with zero problems.So i took a picture and ordered the same device that evening,for next day delivery.I keep it in the car and i am happy to say i have helped other drivers on numerous occasions.So far i have started my 3.5l Mercedes,Audi diesel,Toyota Hi-Lux,Land Rover sport and a 3 ton mini digger. The power is quite surprising.it especially shocked the digger driver..The other regular use i have made of it is the torch function and the USB charging function is superb. It charges my Google phone way faster than the car socket.If you are considering purchasing a quality battery slab,maybe spend the extra and have the bonus of an emergency jump pack as well?All in all i can't fault it. I've jumped 3 cars,charged my phone up and it still displays 58%.Great strong storage case, good instructions, easy to use and well manufactured. Superb.

It was only after I decided that I no longer wanted to feel frustrated by using what might have been weak jumper leads or be dependent on friends being available when my car wouldn't start that I decided to purchase the Flylinktech Jump Starter from Amazon. The description looked good and the price was very favourable. Knowing that I didn't need the help of anyone else when I had a flat battery and that I could use the charger to recharge my mobile phone seemed very appealing. Nevertheless, after being attracted to the product there was still a 'final time' of the fruitless use of jump leads before I placed the order. I wish I hadn't delayed. The Jump starter arrived with a 84% charge, so it didn't take long to reach 100% - and then the total satisfaction of starting the car (Skoda, 2 Litre diesel) first time I used it was such a relief I could hardly believe my luck! moreover, I was very pleasantly that the first-time start only dropped the charge in the Jump Starter by 12% (to 88%) - I had anticipated a much bigger drop. I was so pleased that I recommended it to my cousin who then placed an order with Amazon and he also experienced the same very satisfactory result with his car (MIni, petrol powered).Accordingly, as I no longer fear the possibility of a flat battery (which usually occurred after not using the car for four days) I have no hesitation in giving this a 5* rating, especially now that I'm saving more than £20/month by ending my subscription to a national break down and recovery provider. Saving money and getting peace of mind from having a reliable charger always to hand isn't a bad combination for anyone!
