Stand-Alone, Universal Battery Charger?

by gregoryopera Jan 12, 2014 2:10PM PST

Having recently broken my Sony Xperia Z's screen, I replaced it with the new Kogan Agora HD+ as an interim solution until I can afford another Sony smartphone... I might however, continue to use this smartphone as for a budget smartphone, it's actually pretty good thus far (ask me again in a month!).

Anyway, I digress.

Alongside my Agora HD+, I also purchased a second battery... But I did not stop to think how I might actually recharge this battery, so now the only way to recharge this second battery is via my Agora HD+ itself.

Therefore, I am trying to find a universal, stand-alone battery charger for mobile devices, that will recharge batteries independently of the mobile device.

I have actually already found one such device:
http://www.accessorygeeks.com/universal ... arger.html

However based off the reviews on that page and a related YouTube video, the quality and practicality seems to be a bit of a mixed bag... So I'm trying to see if there are any of alternatives that might meet my needs.

Any further suggestions for similar devices would be appreciated.

Answer

As there is no universal battery, no universal charger.

I see lead acid (sealed an not), NiCad, LiOn, LiPo, NiMh and other battery technologies besides voltage and amp-hours.

All this means is that the hurdles to make universal chargers are too high.

Try this. Turn off the phone and charge up a battery to its peak. Pull that out and put in the next battery. Now in a week pop in the spare battery and see how much charge it shows.
