Car Jump Starter,Power Bank 12V 30000mAh Car Battery Jump Starter Auto Engine Battery Charger Power Bank Car Booster Battery

I've had this product for about a week so far and have conducted some tests.One thing I really wanted to know was the real capacity, it claims it has 30000mAh, after many many attempts I have concluded that this isn't infact correct, at most the pack has roughly 20000mAh which for the price of £37 isn't a good deal at all and there is alternative brands out there that don't lie about their products.It came in a nice little carry case with all accessories and a little manual so that one can understand how to operate the product.I did a small test on the Jump starter kit that came with this power bank and it did let off a big spark when striking each + & - together which could be considered an idiotic thing to do but when I first saw that this product was even advertised as such I wanted to test to see if that was even a thing, I do have a dead battery which I could put in my car and fully test this feature out but from the previous test it seems capable of perhaps starting a car up.The LED on the device is really quite good actually, it's nice and bright and has a range of other modes such as SOS or just flashing rapidly as well as just constant light.It charges devices up quite quickly as well which is a bonus regardless if it doesn't actually have the full 30k mAh as it claims, however I must disclose some more bad news, It doesn't seem to charge that well for more than just one device, I plugged in my Phone and Tablet and my phone would keep charging while my Tablet would stop, it's an odd one, it would charge for a bit but then just randomly stop, I have other power banks that handle multiple devices charging without any issue so I can't quite understand why this is the case for this one.It's not very heavy either which at first was raising alarms for me on how well this product actually would perform, the quality of the item is good though.Overall I would say it's just okay, I'm not disappointed in the device, I do wish it was 30000mAh though, but regardless of that fault, everything else works as you'd expect.

Part of the reason why I bought this Power Pack was because it is supposed to be powerful enough to start a 6 cylinder car, which I have. I haven't tried it yet because I haven't had the need. The other reason, part of the thinking was, if was that powerful, it would be great for charging my ipad and mobile whilst away from home. Sadly not the case, after just a few hours with my ipad plugged in, it was showing three out of the four power indicator lights, i.e. 25 per cent discharged. My wife has one of these packs from another manufacturer, much cheaper, much smaller, not for starting a car though, but the point is we have had mobiles and ipads plugged into it all day and it only dropped by 25 per cent. I am sorry to say, would not buy one of these again. Disappointing.

The size of this workhorse is tiny about the size of a mobile phone ..also has a built in 3 function torch with on ,strobe,and S.O.S flash for emergencies ,plus 1 usb port for charging mobile devices and a mini usb charging port 3 type splitter cable included ..see in picsAnd it does what it says too ..Brilliant product ..thats why i bought two ... Theres nothing worse than parking your car in the middle of nowhere ..then returning to find youve left the light on or radio running and the battery has gone flat ..or like myself, i had the hazards on while clearing someones garden rubbish and ran the battery flat .. I wish i had this awesome bit of tech with me instead of trying to push start the car by myself ..lolVery happy with this ..Fantastic product !!!P.s. Ive just had a look through the reveiws of the dissapointed buyers of this product and they all are basing the fact that this runs out quicker than so of the portable phone chargers..!!Yes!! Maybe it does but this product is made mainly for the starting of vehicles ..not for the charging of mobile phones ..Of course it will discharge when you have it plugged in for hrs ..You only use a miniscule amount of charge to start a vehicle you dont need to leave it connected ... To all those who have not even tested starting thier vehicle with this i urge you to take out the battery on your vehicle and connect this awesome piece of tech and try and start your vehicle then alter your unbiased opinions( this is not a phone charger )
