Good price if you're in the market for one of these.

Please don't vote cold if you're not a fan of these devices. I've posted the deal because it seemed good value for what it is.

Should start most petrol/diesel cars up to 2000cc. Also charges phones, tablets etc

Same capacity as the Aldi/Lidl ones selling for nearly double the amount. RAVPower are a respected company producing decent quality goods. Lots of positive reviews for their products on Amazon.

To get the discount simply click on 'Promotional Message' and select 'Save £8.50 when you purchase 1 or more RAVPower Car Jump Starter 8000mAh power bank offered by Sunvalleytek-UK. (Terms and conditions apply) '


Add to basket and discount should show at checkout

They're awesome little gadgets, mines came in handy loads of times. It was something I got sent to review but would of been more than happy to pay, jumped a number of cars with it.
Mines 15000mAH though so nearly double this.

Not 100% sure. People skeptical that they'll work as described I guess. Lots of positive reviews for this and similar items so sure they must do as promised. This is the cheapest I've seen for a branded version from a reputable seller so not sure why voting is so far cold!
Probably because if you need to jump start your battery it's goosed!..

Put your money towards a new battery.
In an emergency a God send, but the problem is they just sit in glovebox forgotten, gradually losing charge, charge then when needed its a flat as the car battery!
I have something similar which saved my bacon twice but it is 800 amp peak, I wouldn't risk with anything bigger than a 1 litre petrol whatever the blurb says
As motorcycle owner this is perfect. Powerful enough to start 1000cc motorcycle that’s too Heavy to push. Small enough to go in ruck sack or under seat storage. Simply mistakes like leaving ignition on or an alarm that drains battery are my worst fear. This is worth the money even if I never have to use it in anger.

Or you've just left your interior light on overnight by mistake so you'd be mad to buy a new battery.....

Because what you can do is go to a car battery shop and buy a new car battery if yours is over say 5 years old and say winter is approaching. And join the AA

As said above, there are many instances where there's nothing wrong with the battery, it's just been run down because someone left an interior light on etc.

Crazy to spend up to £100 on a new battery when there's nothing wrong with the old one!

Even if this device gets you out the poop once it's paid for itself if you don't have breakdown cover.

Besides, the car could have developed a fault, like a broken courtesy light door switch. In which case you may end up with a flat battery more than once through no fault of your own.

Please provide factual information to support this. If they say it will start a 2L car what reason do you have to doubt them?

100% I have a similar kit, take it away on trips, peace of mind knowing that everyone's bike will start if the battery is flat, or phone needs charged etc. Everyone should own something similar, an interior or sidelight left on can drain a good battery to the point where it wont start the car etc, but will be fine after a few miles driving and alternator has recharged it. Can also be a lifesaver if you have a parasitic draw (wont fix it but allow you to get to a garage)

Because I had a Bestek one of the same peak amps and it would only turn over my 1.8 litre petrol once so I sent it back to Amazon. I then tried an Anker and ultimately bought the one I have now which was branded Anypro. I also have a 1.6 diesel and the Anypro will crank and start that with no car battery in (although not recommended as it could ultimately fry the jumpstarter) I wanted to see if it would start with a totally dead battery which I didn't have. The Anker (600A one) wouldn't start my 1.6 diesel (weak battery in situ) even though Anker claimed it would. All Chinese manufacturers of battery packs, generally seem to blag a bit IMO, especially about battery capacity. What makes you think they're gonna have gone out of their way to quality test the cranking performance on a range of 2 litre petrols, especially when the conditions are cold when your car battery is likely to fail? I could just as easily push the burden of 'proof' back to you.

Fair enough, I appreciate your explanation. I agree that there are an infinite amount for variables to take in to consideration here and due to weather/varied compression ratio etc in different cars, even with the same size engine that this device may not work in all conditions. I still rather have it in my glove box than nothing at all.


Can't understand why the deal has gone so cold though. Can any cold voters post a better deal? I'm guessing not!!

Even the unbranded versions of these on eBay go for over £40

As I previously said, if you're in the market for one of these and on a budget, you're unlikely to find cheaper...
Its gone up now so must have some buyers! Best to borrow a duff battery from a scrapper and try on your vehicle perhaps? They don't sell mine anymore but about same spec as this amazon.co.uk/gp/…ump with the laptop charging facility should you wish to experiment and take advantage of Amazon's excellent returns policy.

Also don't forget to boost charge every 3 months or so.

Price hasn't gone up, you just add the £8.50 voucher to your basket and the price drops to £25.49

Noticed earlier they still have similar item left in my local lidl. Exactly the same capacity/output but they're selling for £40

If we are having a philosophical argument about cost-effective risk mitigation, I suppose it depends on the value of your time and the activities you perform. Also car batteries at the end of their life can cause premature alternator death due to diode overheating componding your costr of repair. So for me £100 on a new battery every 5 years or so/ as soon as it causes you to lose confidence is a complete no-brainier. Thus negating the need for this jump-starter.

Well I have a hybrid car with a relatively small 12V battery which can run down to the point of not starting the car with things like checking out the head unit for half an hour or so without the engine running. I had thought something like this would be handy but due to the lack of heat didn't bother buying one. How I regretted it when I returned to the airport this afternoon after a week away to find the car wouldn't start. I think we may have left the interior light on after trying to find the car park info on arrival at 3am (not the clearest of mind - the car reg number reader doesn't seem to work on my car). The battery (Bosch) is only 2-3 years old so I doubt it is knackered yet. So if you don't mistakes and always have a good battery you wouldn't need one of these. I've ordered one now.

So from what you're saying, this also negates the need for carrying jump leads?! Jump leads have gotten myself and many others out of the ***** many times over.
If you'd rather call a breakdown service and then spend £100 on a new battery that's your choice. Myself, I prefer to make sure the battery is end of life before buying new - I've had plenty of batteries that have lasted up to 10 years.

The point of this site is to point people towards a good deal. As there hasn't been one of these posted at this price point by a reputable seller /manufacturer before I would class this as one of those. It's a pity people on here aren't voting according to the 'deal', otherwise you may not have been caught out. Bummer
