It's rare we see a sure-fire petrolhead gift idea that's not silly money but this is one.
Jumpr is potentially one of the most useful motoring gizmos invented – it's a portable charger not much bigger than a smartphone that's claimed to pack enough power to jump-start a dead car. No more lugging that boat-anchor of a Halfords charger from the garage, only to discover it's out of charge too.
Up to 300 amps possible with a 6Ah capacity
The device comes from a seemingly well-established Californian smartphone charger specialist called Juno Power so, who knows, it might actually work. The battery pack is lithium polymer instead of lead-acid in standard chargers, hence the high power-to-weight ratio (it tips the scales at 200g, versus 8kg for Halfords' Power Pack 200).
The maker claims it'll deliver up to 300 amps to a 12-volt battery, with a storage capacity of 6Ah (amp hours). Looking at the specs of the Halfords device, that's well down on Halfords claimed 17Ah, but Juno reckon it'll be good to power up four and six-cylinder engines with no size limit, while Halfords says its model is good for up to an engine size of 2.0 only.
And it can charge your phone!
posted a video
on YouTube showing its device recording a voltage of 12.54. There's also
another video
from the company claiming to demo it juicing up a dead Honda via its own dedicated jump leads. We're very much hoping it's a valid test, particularly as we like that you can also charge up a phone from another socket on the device.
The price is pretty good, with the company currently offering it an introductory $69.99 (£41.50). That's almost half what Halfords charges for its Power Pack, albeit without the extra gadgets like the invertor and tyre compressor.
The big question remains: does it work? We've put in a request to test one, so we'll get back to you on that. If the answer's yes, the AA should offer these half-price to members. Imagine the call-outs they'd save.
