I posed the 14000 /1000A peak model not long back which was decent value at the time, although now the 10000mAh / 400A Peak model can be had for £29.99, which might suit people better. It also has a little torch built in, which is ace for finding things that fall out of your pocket and go under the seat (Just me?)

Works as a powerbank as well, so good to have in the car all round, really. When I first saw these devices, I questioned them fairly heavily and I know a fair few other members did as well, although that said a lot of folks are finding them really useful.

But how long would the charge last. You come to use it and find it's flat ?


Just start the engine and plug it in to charge... oh, wait...

Get a coupe & use one to charge the charger. Or you could just keep your eye on it, & charge it up from time to time. Same as anything that looses it's charge i suppose.

Mine used to last about a couple a weeks in a cold car glove box before it would be self discharged and would need to be plugged into the mains for a recharge

Good quality ones will loose very little in a year, one of the advantages of lithium ion cells but the low quality ones are a gamble.

Have one of these, and used it to help boost a car I keep on a trickle charger, where the car had not been started for a few months Whilst the battery is still excellent, it is about 8 years old and would have started the car but you can tell its lost its edge. Attached this item and worked a treat

I should add it helped to turn over a V6 3.2 Petrol engine

I've no idea really, however it came fully charged, I've used it to boost that car starting and it's still on full charge - had it about 4 weeks
They work ok is your car battery is slightly discharged but usually the only time you need one of these is when something has been left on and the battery has gone flat. When that happens this type of Jump Starter simply isn't up to the job.

Tried four different sizes of these Jump starters from Amazon and ended up sending them all back. Much better to get a decent set of jump leads.

Seems like overkill
i have one and got me out of a jamb a couple of times just great to have in the vehicle charge lasts at least six weeks, and so far never really looses its charge fully, starts a 1.6 ford diesel engine no problem

Like all of the ravpower products.
They are spamming HotUKDeals all the time.
All of their deals are getting hot in no time. Even when price or products are just average.
will try it.. if it's shite it's going back, lol.
Would anyone know if this would start a 3.3l petrol HYBRID? Unless I am mistaken the 12v battery in hybrids is only needed to start the ECU which then fires up the car’s hybrid batteries+engine - hence the 12v battery in the car itself is a bit small.
Worth googling. I was sceptical but lots of people swear by these. Ive got two for my Motorcycles. Only problem for me is the crocodile clips are for a car

Sadly this seems to be the case for these types of unit. I have looked at a number of them, even the ones at the £100 mark, and the negative reviews all concur. Shame, as I like the idea of having that one of these as a backup. I guess you have to spend hundreds on these things to get one that you can rely on, but I certainly can’t justify that level of spend. Cheaper to buy a second battery, although that is not much use when you are out and about of course.
The reviews for this look to be so fake (see above posts) that you'd have to be barmy to buy one. Any product or manufacturer that gets this review of its reviews needs to be treated with the very greatest of suspicion!

So, you're saying that you're unable to tell what is and what isn't a fake-review, though you believe a review of those reviews.
You and your money will soon be parted.

Have a look at fakespot.com/ - it might educate you on the subject of fake Amazon reviews and save you from buying over-hyped cr@p.
One of these started my TT when the battery was stone flat.
ok this is dodgy as hell, it won't accept my review but i am verified purchase! and i thought there were some less than 4 star reviews before, but they've all gone.
ironic because i was going to write a fairly positive review. it starts a small car. but the capacity is only about 5500 mah useful. tested with a load tester.

Need to check the specs for whichever one you buy, but generally listed as 3 to 6 mths.

Actually my daughters Peugeot 308 was flat as a pancake this weekend, and one of these (albeit slighty meatier - was the DBPower 10800 500ah model) started it no problem at all. They are a brilliant piece of kit.

Jump leads don't help you if there is no other car to connect them to, and these days on modern cars you also run the real risk of frying your ECU (or their ECU) using jump leads, which can be a very very costly thing. You should also not connect jump leads whilst the key is in the ignition:-

"Don't connect the jump leads with the key in the ignition; insert the key only after the leads have been connected. Connecting the leads with the key in the ignition may corrupt the coding between the key and the ECU. In some cases that's irreversible, which could cost you a new key or a new ECU - or both

Why would buying a coupe make a difference, nice cars but they still suffer from a dead battery like other cars?

If you meant buy a couple and use one to charge the other then I cannot understand you're way of thinking!
Didn't work on a 1.6L petrol. Just flashed red and green, indicating 'standby.' Tried more than one arrangement to ensure a solid connection. Got solid green only by holding the boost button, but car wouldn't start.

The Green Flag breakdown guy who came to jump the car said the car battery was 390A so a claimed peak 400A power bank, which likely doesn't perform to the stated values, might struggle; the breakdown company's car jump batteries were rated for 1000A of current and started the car immediately. Battery assessed as being in a healthy condition.

This power bank sent back to Amazon as not fit for claimed purpose.
I bought a similar Autek device for £16 last year. Started my Mum's Jazz twice now when the battery was flat after being sat in the boot of my car for weeks after being charged.

I don't think this product would be up to starting big diesels but should be fine for smaller petrols.
