The laptop charger that originally came with my hp laptop broke in my laptop bag around 3 months ago. The adapter plug on my charger had completely bent out of shape and the wires were poking out underneath. I tried to bend it back into shape to charge up my laptop, but it made a crackling noise every time I would plug it in. Because my laptop hadn't been charged in around 3 months, I thought it would take a while to charge up. When my new charger was delivered, two days after my order when I only paid for standard delivery, I plugged it in and my laptop started up straight away without fail. I have had absolutely no problems with this charger what so ever, it works perfectly. As they say, "everything it says on the tin". It's also longer than standard size chargers, which is extremely handy. I would defiantly buy off this seller again. And it only costs a third of the price of HP chargers you can buy off the official site. Amazing value for money.
