This IS a HTC charger, it is for the HTC Desire, it does cost a little more than a universal non-original but it is more solid has a better quality feel to it. It is also quite handy that it has a USB connection for the cable. The coiled wire on this charger is not massively long but adequate in most cars to reach from the cigarette lighter socket to a mount on the dashboard. It may not reach all the way to a windscreen mount if you have an awkwardly sited socket. You can always use the cable that came with phone as it fits perfectly into the top of the charger.
(I have always been a little bit wary of buying non-original or universal charging equipment for electrical goods.
They always tend to look better value as they are usually significantly cheaper. HOWEVER: When it comes to protecting your investment it is always better to take original equipment and you will be less likely to be disappointed or have your electronic device go up in flames. I once bought a charger described as original and it wasn't, the connector was the wrong shape for the socket on that particular phone. I didn't realise this until I had plugged it in and damaged the charging socket on the phone.)
All in all, it does what it should, it is as described and it only loses one star because the length of the cable may not be enough for some cars.
