    Rated 4 out of 5 by Just what was needed Does what it says on the box. Did seem to get a bit warm having been on all night, but it didn't cut out, so all was good. Seems a tad expensive though for what it actually is. 21 May 2016
    Rated 5 out of 5 by Handy adaptor Just the job for charging up those items from the mains, for which you only have 12V leads. 03 May 2016
    Rated 1 out of 5 by No Power This item was bought to power a tyre pump but could not do the job 01 May 2016
    Rated 5 out of 5 by Does the job Does exactly as it says on the Tim. Could be a bit cheaper though. 07 March 2016
    Rated 1 out of 5 by Useless article Refused to function with my (Halford's) digital tyre inflator. I bought a manual foot pump instead! 03 March 2016
    Rated 5 out of 5 by Works absolutely fine Had this for a couple of weeks. Used it once so far, for a stretch of over 8hrs continuous, running my fan-operated cool-box. The transformer became (expectedly, and very acceptably) warm over that time - but it DIDN'T get hot. So, recommended at this time for my intended purpose of running my cool-box. 22 February 2016
    Rated 5 out of 5 by Does the Job Well We've only had this for a few weeks but have already used it for several lengthy periods on two different portable fridges and it worked perfectly well on both. 06 December 2015
    Rated 4 out of 5 by Does what it says A replacement for a similar one that went missing, it works as advertised. Not sure why the cigar lighter socket couldn't be built into the transformer box; I see no advantage in the additional trailing lead. It is a pain to get back into its packaging for transportation, as the various leads, plug & socket don't seem to go back where they came from. Used for several hours to keep French cheese supply cool without any sign of overheating. 02 November 2015

Some of the parts we sell here at Halfords have been reconditioned. These will carry a Refundable Deposit or an extra surcharge amount. When you add one of these reconditioned items to your basket, we'll add this extra cost automatically.

Once you've sent us your old item we'll check it over, and then refund you the full surcharge as long as everything is ok.

Before you return your old unit please make sure it's in re-serviceable condition. So if you're returning caliper casings, you'll need to double check they aren't badly damaged or broken. If the part you've sent is found to be unserviceable, we reserve the right not to refund the surcharge.

Please note that if you're returning your old unit to our National Returns Centre then this will be at your own expense.
