Universal USB phone charger

In the wake of the Japanese tsunami in march 2011 one of the first things people wanted to do after they had reached the safety was to recharge their phones.

Imagine being faced with many people all wanting to charge their phones at once. Despite the market dominance a a few mobile phone makers there is still quite an array of charger plug formats.

When i first saw this item i could see just how useful it was. I highly recommend it. It’s the most important part of my ‘charge a phone virtually anywhere’ kit.


Note while it has the correct connector for the Apple iPhone/iPad it may not work due to Apple’s proprietary hardware restrictions.

So you should look back in the box your phone came in, and find that weird cable with USB at one end and your phone connector at the other and keep it handy.

Most phones support charge via USB now, and even it you don’t use such a cable to connect to your computer its useful for charging.

Fast charging: you may find a 2.1A USB port occasionally and this will allow you phone to charge faster if your phone supports fast charge.

For the record USB is normally 5V DC 500mA, the fast charger works by shorting pins 2 and 3 the green and white wires to ‘tell’ the computer to supply more current, 2.1 Amps.

cost about $5-$8 available in some $2 style shops, may come with accessories like car to USB and AC to USB which are both worth paying a few extra dollars for.
