A great small charger, that does the job well when needed to jump start my car.

This product is great. At first I was not sure whether to buy it, due to the length of the leads, as I have a BMW 1 series from 2011, and the battery charging system is different from other car manufacturers, so I was hesitant. Instead, I had bought a standard set of leads from amazon for £17, but they just would not work, when I used my neighbours car to help me jump start my car.He has a set of leads from B&M, which are RAC branded, and cost £10, and they worked a charm when I used them twice. So I sent my leads back to Amazon, and decided to buy this charger. And, to my surprise the leads were long enough to jump start my car. I followed the instructions, and the device worked a charm. The build quality is good, and with its minimalist size and design, it is small, which is also great, as its compact enough to put it anywhere you want in the car. If an improvement can be made, then I would want 2 changes, 1, the charge on the device to last longer. As other customers have pointed out, each jump start reduces the charge Percentage on the charger by 25%, I found that a little discouraging. 2. Increase the length of the leads by a couple of inches please.Despite this, the product is great. I would highly recommend it.

After two months just gave it its first trial, left the hazards on overnight Der! Flat as a pancake. Quick clip onto battery and flick the switch and hey presto started up....Brillo

Very handy well made

Good piece of equipment,, very handy for jump starting instead of bulky leads. Small and lightweight but packs a punch. I have used it half a dozen times to start vehicles with a dead battery but I found I had to charge it after every use as there wasn't enough power for the next vehicle, however the vehicles I was using it on where completely flat. It's also well made and quite sturdy.

Simple and effective

I noticed this product is much cheaper than equivalent products that do the same thing.Context of why I bought it:My son had a car delivered it hadn't been driven for two months. Dead of winter. The battery was dead. Not so much as a noise when turning the key.I mulled over calling the garage out but decided having one of these might be useful going forward.It arrived charged. I put a few more volts in and connected it up.Car turned over first time. Thing pretty much paid for itself right there and then.Because I never took the car for a long drive battery died again overnight.Same thing next day. Dead battery but using this it turned over first time.It now lives in the glove box and I get real peace of mind from that. My son is only young.Bonus functions - torch, usb and usbc charging capability.So, from my limited use it’s been a superb investment.Details.Car I used it on, only a little 1.0 litre engine ( so tiny).Use was almost out of the box so can’t comment on how well it holds a charge over time, for example if it was left in the boot.Great bit of kit. My experience has been nothing but positive ( battery joke in there somewhere..).

Motor Magic!

I bought a new Corsa in January, but decided to keep the old Corsa for my son who is learning to drive. 3 months of sitting on the driveway. Its April; of course the battery is DEAD 💀We tried bump starting AND brand new jump leads - nothing, nada, completely kaput. This little machine comes along and, granted at the 2nd attempt, Bruummmm! 🏁 Absolute game charger. The times I've flattened batteries at car boot sales and leaving lights and various items charging. AMAZING! Well worth the money 🫡

Absolute life saver.

After having to work away from home for over 2 months. My car was left unused and its battery had drained. This jump starter saved me when I returned, to my surprise it arrived the next day to a click and collect counter. And the jump starter was already charged up to 75% out the box. To be on the safe side I plugged it in and it was 100% charged in less than an hour. The instructions had a handy guide that tells you the red lead goes to the + terminal and the black lead goes to the - terminal. Apparently the jump starter would automatically detect if the crocodile clips were placed the wrong way around but I didn’t test this. After a few seconds my car engine miraculously started. For its cheap price I really can’t complain, having done its job it is excellent value for money compared to other jumpstarters that are 2 or 3 times the price. It’s a compact size, about the size of a large USB powerbank (which it technically is) and would fit in a glovebox of side storage in the boot or door pocket. My only slight criticism is the cables are a bit short but it still did the job resting it on the engine cover and it took me a minute to find the boost button on the side of the crocodile clips.
