great product, nice finish brushed aluminum, a handy charge indicator, a recharge 4.5A which is mandatory if you want to reload a pc, the presence of a USB port allows 2.1V to quickly recharge a this or a tablet by cons, I took this high capacity battery for my laptop without really knowing what he was consuming, I thought I could recharge it 2 or 3 times but in reality it is only 1 time. To find out how your laptop consumes install BatteryMon, note the number of mah that the software gives you (or if you know the number of mah it's good) and multiply it by the number of this cell in your battery you have the conso your laptop: eg jai a 4843mah battery with 6 cell 4843mah therefore x 6 = 29058 mah both say that the battery recharges to 80 pc 90% voila, otherwise it is a very useful battery I recommends
