i found this in b&m store. i thought it would be good to keep in the car just in case of emergency. it was marked up for £14.99 but reduced to £2.00 in store. handy if like me u leave the lights on.

I've had regular sized jump leads which didn't start a car once. I then used my heavy duty ones and they started the car. When i say heavy duty, i mean the cabling is as thick or thicker than your index finger.
So with that in mind, i find it hard to believe that this product would ever work. The required amperage cannot be supplied by such small wires, they would either physically melt or just wouldn't work at all. It really wouldn't start a car up. It MAY trickle charge the battery incredibly slowly, but it wouldn't start a car.

I don't see the point, any man worthy of genitals has a decent set of jump leads in his car.
This must be for Londoners or something?

Ever so slight over reactions I think, sometimes the difference between a car starting and not starting because you left your lights on for a few minutes is minimal, two pounds, throw them in the glove box and you never know, they may save you a bit of time one day-remembering to turn your lights off may help :wink:
As for then I'd have to say that some people have made some seriously poor decisions in their life if £2 wasted makes it onto a list of regrets! :wink:

I haven't had mine long enough to confirm by myself, but the specs say these lose less than 2% charge per month, so around a quarter in a year. So theoretcally, the min to start my big diesel being 50% soc, it could be left for 2 years and stiull start it. A friend has one in his holiday place, and it starts his car after 6 months when his lead acid is dead of course.
Careful to get the correct spec for what you want. Mine is the min spec for my car, you can get a 400A 10k mAh for small cars. Lithiums can be dangerous, and you're warned not to connect a one designed for a small car to a big car.

Total waste of cash and, worse still, some may buy it and rely on it to get them out of a difficult situation, which it won't. If you want decent insurance against a flat battery, get a heavy duty set of jump leads or, much better still, splash out 70 quid on one of the new types of car starters, lithium based delivering 700/800 amps (google Suaoki) which can be stored in the glove compartment and are ready to go, no need to bother someone else for a jump. I've got one and it started my 3.5 litre diesel when it had a completely flat battery in near zero temps (so about as difficult to start as you can get).

Googled it, our of curiosity does the charge of the unit deplete while left in the glove box? aka will it be flat two months down the line when I need it if I don't charge it weekly
For £2 it may get you out of a situation,the cigarette lighters will be fused in both cars and the lead will have a fuse so cant seeing there being any issues with damaging anything.

I wouldn't buy it, I turn my lights off. And if I'm going to have a list of poor financial decisions it's going to start a lot higher than £2. I think your hyperbole detracted from your point rather than enhanced it.

It's a 12V battery to battery charger. Since they are usually pretty expensive, more than likely that this is a peice of junk. However there is nothing wrong with the principle.
Thinking it could be useful for people with a leisure battery to charge a run down main battery (just replace the cig lighter plug with croc clips)

Crikey that's a POS and pointless. Surely you use jump leads if you have another car available to charge from. Oh and this will only work on cars who's sockets are constantly live (i.e. Don't turn off when car does). Are you expected to have your friend sit in their car running for 15 mins so their battery doesn't also die?!
Get a booster pack for the glove box if you want the cover or a set of cables in the boot.

I totally agree with this guy (J4GG4) ask yourself why is it £2? Answer does not work. If your car battery is so bad that leaving the lights on for a hour drains it put the £2 towards a new battery. I know I left my car lights on for longer and n the past and it's been fine. BTW COLD from me

Blowing yours or someone elses car up or damaing it is a risk you're willing to take for £2?.
All i will say here is, good luck and please google search from experts about this type of device before you buy it. It may seem like a cheap item for £2 but you'll learn the hard way i guess. Better to have the correct tool in the first place to do the job.

Looking at the teeny pic it connects to the cigarette lighter(s) yes?. These do not work and can actually damage the vehicle(s) electrical systems. I'd be taking it back and looking to get some proper jump leads if you want something for 'a just in case'.

It'll be the worst £2 you've ever spent, by that time comes it'll be too late to return it.
Do you also think you'll find a motorist willing to allow you to plug this thing in their car to help you?. Then sit there for 15 minutes?(btw it wont be 15 mins!). What if their car catches fire from this cheap product?. Or their battery dies due to you sucking its juice. Not worth the hassle, honestly.
Do you know even £1000 trickle chargers can take 24 hours to charge a battery up?. So how will this £2 one do it in 15 mins?.
Get yourself a smart charger about £15/£20. But really, if your battery is in this bad shape you'd need to get a new one anyway for £30 - £60.
Save your £2 i say.
