Found 6th Feb
Been looking at these for a fair old while, was a bit dubious over them at first, but i've seen some decent reviews and positive comments on here on them and thought i'd give it a go.

This one is £42.99 if you Redeem the voucher under the promo section on site, which seemed a very fair price considering the last one I saw was £39.99 with a 10800mAh power bank / 600A / for upto 6L - This one has a peak of 1000A / 14000mAh / upto 7L

Pretty cool gadget to have in the car just in case

  • 1000A Works with All 12V Gasoline engines: The peak current of 1000A kick starts all gasoline and diesel engines up to 7L with a 12V battery, over 20 times on one charge
  • Extra-Safe With Built-in Intelligent Protector: The intelligent protector is built in the battery pack while with other brands it is built in the clamps; this protects from fire on the clamps which can cause melting or explosion
  • Massive 14000mAh Capacity With Micro Input: Charge the car jump starter via car charger, wall charger or even another power bank; reload the jumper in just 5.5 hours with the DC5V/2.1A AC charger; charge your iPhone 7 up to 5, the iPad mini 1.5 and the Galaxy S7 3 times
  • Quick Charge 3.0 + iSmart Technology: The Quick Charge 3.0 technology charges your phone that supports quick charge with a 75% faster charging speed and the 2 iSmart USB ports support a maximum current of up to 2.4A each
  • Boost Button & Status Light: If the indicator light is green, you can jump start your car; if it is red, you need to check the connection of the clamps and polarities, and make sure the battery level is over 20%

It's a 14Ah battery with a nominal voltage of 3.7v, so call it 3.5Ah at 12v (allowing for losses). That's 3.5 x 3600 = 12,600As. So in theory it can maintain 1000A for around 12 seconds.

Power = 1000 X 1000 X 0.1 = 100,000W of HEAT for 12 seconds? Lolol Right... The cables only look capable of 30A nm 1000! All bull. This will probably do 70A tops.

Tap promotions and there’s two offers, first of which is to save £23 which reduces the price of this item to £42.99 as per OP.
There is a promotional voucher at the bottom of the page which takes off £23
Ordered. Thank you.
Got one a couple of months ago, cars been sat while ive been ill
This paid for itself in a couple of days getting it going again
Well worth the money
Going to leave my headlights on all night & stereo on full blast, just to test it.
Bought a energizer one from Aldi,few days later left my lights on by mistake over night, forgot I had bought it and tried to bump start my a few times,,nothing the battery was to low ,remembered I had bought one just has I was going to take the battery out and Wow 1st time start ,I will now have one of these with me at all times.
1000A? bullocks. That means the entire battery bank could discharge itself in just over a second.
Me thinks they want to get rid of their hoarded items but maximum profit
This probably can start a car engine, but there's no way it could output 1000A. It physically wouldn't be possible across those cables to the jumper leads. Maybe 150A, but marketing it like this is just false. I think if you want to buy one this is probably a good deal, but take the figures with a pinch of salt.

crocodile clip cable does not have the diode protection box attached to it (lead could be cheaply replaced when diodes fail) , protection must be inside the battery pack ( so pack scrap when diodes fail) - pity

Well it could, it'd involve fire
I’ve looked at a few of the boosters and for just about all of them, if you check the negative reviews then they all seem unfit for purpose. I am happy to pay more for a quality device that is reliable, but has to work on the one time I require it. Any suggestions anyone?

er................................no!

You cannot magically transform 3.5amps into 12600amps!

It is a 14Ah battery so it will give around 14amps for one hour at 12v.
If you want 1000amps it will last 14/1000 of an hour = which is around 50 seconds (actually it would not last that long but that is beyond this explanation). Unfortunately the whole thing would probably have melted if you tried this but note they are saying that it will give a peak of 1000amps which it might maintain for no more than a second - just enough to get your engine turning over then a lower current to keep it going until it starts.

I guess that whether this will work might well depend upon your engine. Small petrol engines require a lot less starting power than a big diesel

or just unclip the battery and test starting the car direct from the jump pack

it's how I used to test them for amazon reviewing, if it can start on its own it will easily start a car with a run down battery in the circuit.
I have used an anker branded one a few times to jump various cars and vans they work brilliantly.

I am sceptical every time i use it but engine starts first turn everytime.
Chris521 h, 27 m ago

It is a 14Ah battery so it will give around 14amps for one hour at 12v.


I doubt it. Most battery packs are quoted at the nominal voltage of their constituent cells, which is 3.7v. They then convert that into 5v for USB output or 12v for jump starting, so the actual Ah rating depends what voltage you're using. It would be far more rational and honest if they just quoted a Wh rating (which, to be fair, the Anker packs do in very small writing on the side).

> You cannot magically transform 3.5amps into 12600amps!


Sure you can (well, magic doesn't come into it). Give me 3.5 amps at 10,000 volts and a suitable transformer and cables and I'll be happy to give you 12600 amps at 100 mV. Not that 12600 amps ever came into my calculation - I mentioned 12600 amp seconds which is just a different way of stating mAh.
I have been looking at these jump packs and there are cheaper ones on ebay that look similar. I do need one that can handle at least 5.5 litres but this still looks pricey even after discount unless you think its a particularly good one?
"This item does not ship to UK - Northern Ireland" hate this shizzz is our money not as good....
Seems expendive to me. Search for Linda store ( from memory, maybe Lunda store) on Aliexpress for portable power pack 600a, they go for £18 delivered to £26 for up to 2L engines. I have one.
Came here for the deals, got physics lesson instead. 10/10 would do again.

Have a look at the NOCO genius boost (also on Amazon) - I bought one after seeing the Motorcycle SOS guy use it on my bike after I was to eager to go for a ride and didn't charge the battery enough...
Could you use this as a defibrillator?

Do the borders not like lithium being shipped for risk of explosion? Some countries don't like lithium ion batteries to be shipped... fortunately not China.
They all use 3x cells in series to get 12V-ish, and the peak current they can put out is limited by the cells, the (sometimes puny) cables and the big diode pack in the lead to prevent back charging. They all seem to lie about the overall capacity, and more importantly the peak current. However, from my limited experience of a different one, they do work (now used it three times), just dont use the numbers to decide which one to pick! It manages about 2 or 3 cranks of my 2.3L petrol engine.
Most have USB outputs, and some have a 19V output which ishandy for a laptop (although the plugs supplied dont always fit).
is the promotion stil valid?
it let me buy this on ful price and car usb charger with 40% of discount... I can't see any other promotion...

Maybe on a flea but 12V ain't going to even tickle you never mind reboot your heart.
I have a very similar one (maybe even a re-brand of this).

Never used it myself on my Ford 2.0 litre diesel, but a guy at work had a flat battery a few days ago and wanted a regular jump start (cables attached and everything).

Anyhow, told him I could try with my booster, but when I hooked it up it only had around 45% charge.

But sure enough, It only went and started his 2.5 litre petrol with a look of WTF? on his face LOL

Not sure how well it would work with a high compression diesel though.

Thanks for the suggestion, but again if you check the one star reviews you will see many people stating that it is unfit for purpose. They amount to 13% of the overall reviews. It’s a shame, because I really like the idea of these devices.

Just look on YouTube, there's some dude that destruction tests them, rather than gives a good review in exchange for a free one.

Just search for "Car Jump Starter Lies", it's the dude with the glasses and beard and homemade hydraulic log splitter.
