How to charge your mobile device without mains power

If you have ever tried to charge your mobile phone or some other device from your laptop, you’ll know that it’s a desperate thing to do. It takes ages! It’s hard to comprehend why would it be any different from charging your device from a power outlet on the wall. In this post I’ll tell you why is that so and what you should do about it. I wanted to bring this out to you, because I’ve also received a couple of questions on how to charge Goodspeed mobile hotspot.

When you charge your mobile device with your USB charger, the power you’ll get is usually somewhere around 1000 mA, depending on the charger. When you unplug the charger and charge your device by plugging it into the USB port on your computer, the power you’ll get is half the amount, 500 mA. Funnily, that’s roughly the amount that your mobile device consumes when in use. So you could wait the whole day and die of boredom before your battery is fully charged.

If you really need to charge via your computer, the wisest thing you can do is to shut down the device you’re trying to charge. Otherwise you’ll just be keeping up the charge-level in the battery, not really charging it. If you’re a heavy user and shutting down your mobile device just won’t work for you, I suggest you invest in a good quality portable power pack that you can use when on the road.

We recently tested a couple of popular rechargeable battery chargers with Goodspeed. The ones I can recommend are the Belkin Power Pack 2000 or 4000 and Nokia’s Universal Portable USB Charger DC-16. The latter also is a sight for sore eyes. I have it in pink ;)
