Well worth the price. Good compact unit

So these were on special the other week and I purchased one on a whim as my other half of the type that is always pumping her tyres up and having to plug in a cable and then feed through to other side of car is a pain and always when you’re in a rush to get out!What attracted me to this was the complete cordless compressor rather than the jump pack as I already have a professional 24v one but that’s an added bonus.Out of the box the unit was at 75% charge but plugged into the USB socket on the wall to fully charge. Note there is no mains adapter with this but if you have USB mains sockets they provide enough juice.Very next morning (Easter Monday) we get the opportunity to use it as we came out to a completely flat tyre.Press and hold the power button and she comes to life. Easy to set the required pressure and a proper lever type adapter. Press the power button momentarily and the compressor starts. It’s a little noisy but all compressors are.On her 18 inch focus 235’s from flat to 36psi took a couple of minutes. I was quite impressed. I did note that the battery had dropped by 1 bar of the battery charge indicator. So in theory you could do the whole car from flat and then have to charge it again.It comes in a soft but tough thick materials carry case that is bigger than the device so no snug fit covers that rip as you get with others. All the accessories and leads all fit inside the case too. parts also no more trying to squeeze everything in.I was impressed that much I put an order in for another one! So we have one per main vehicle. With our corded ones in there as a back up.One word of advice - make sure you do NOT leave this in the passenger compartment of a car as during the summer months the vehicle can get so hot that you could cause battery casings to warp. I had it on a professional jump pack, not this one but I suspect any battery device would be similar.Overall a great little device

Simple and easy solution to help if you have a flat battery.

Great product to keep in your car incase of an emergency, i have had to use it once and it worked well. Just remember to keep the battery charged on the unit as it drains the battery pretty quickly. It also has a handy usb charger port incase you need to charge a battery.

Well tested! Great Product! A Must Have!

I wanted to wait a good while before putting a review of this item up. As we all know, products similar to this have a habit of failing when just out of warranty.However. This product has been faultless in every way.It has started my 3.6 Litre Turbo Diesel Range Rover from flat many times now using the BOOST button. It uses about 20% of the battery to start this vehicle from flat. But afterwards it will go up a few % again, only 2 or 3, but I guess that's just the batteries recovering.I have also used it several times on a 1.3 Litre Petrol engine. And that only uses about 7% from flat. Again, recovering a couple of % after use.I have left it for months sat inside my glove box over winter and it didn't lose any charge at all. I would be confident leaving this even longer, should I need to. Because even after being left that long time it still started all vehicles fine.It even can quick charge at 100 watts, with the right charger.I would say that this is a must have to keep in your car for emergencies.Not only for the ability to start your car, but also for the USB functionality of it. And it also has a 12v output on it with a cigarette lighter attachment. Meaning you can use 12v items on it, such as tyre inflators and so on.So, you can start your car, charge your phone, use 12v equipment, quick charge it. And the battery seems to last for ages.I have not found a fault with it in any way whatsoever! I bought an extra one for the other car and also recommended one to a family member. And I suggest you get one too :)

a must have

Despite its small size, this packs some punch. When you charge it, it retains for a long time, and when you use it to jump a flat battery, the %battery is displayed, so you can accurately tell how many jumps you'll get before charging. You just connect and press the boost button. Much safer than jumping from another car as i'm told that spikes in voltage that wasn't a problem for older cars can cause expensive damage to the ECU of newer vehicles. My friend got one and uses for his tractor. So useful to keep in the car, eg if away on holiday and your battery is flat in the airport longstay at midnight- you've got this in the boot. Or the awkward time a friend asks you to jump his car, but you'd rather not risk you own car's battery or electronics- lend him this. Really good value, and peace of mind. I better stop, as I sound like I am doing an advert rather than a review. As for how many years it lasts, no idea, but feels decent enough quality. Perhaps just a slightly longer lead might be beneficial, but will fit any battery I've seen.

Doesn’t work

Fully charged just tried to use for first time followed instructions to the letter and wouldn’t start a 2.4 engine - went and got proper jump cables and started it using another car in normal way so the problem is this not the car trying to start
