USB Charger

[tippyclubb]

I ordered the wrong charger wanted a wall unit. I'm nervous to use this USB thing because I have read it can fry a computer. I've already fried one battery and would hate to do that to my new computer.

Do you charge your battery with the USB problem free?

What is the rating on the charger ?

 

[tippyclubb]

Model: USB-A
Input: DC 5V
Output: DC 4.2V 420mA

That should be fine. It's the passthroughs that you have to be careful with. A charger made to fit a USB port surely won't damage the motherboard.

USB ports are good for 500mA so it should be fine.

Well the e-go and riva battery are 650mah????? I think I don't understand what your saying if mine are 650

 

[chrispete]

420mah is the charging current, 650mah is the storage capacity of the battery.

420mah is the charging current, 650mah is the storage capacity of the battery.

Does that mean I can use the USB charger with my Riva and e-go 650mah.

I am so confused.

420mah is the charging current, 650mah is the storage capacity of the battery.

You must have made a typo.

The 420mA is the maximum current the charger can supply. The 650mAh is the capacity of the battery. Working around these numbers it means that the charger should be able to charge the battery in around 1.5 hours (420 x 1.5 = 630mAh)

The charger should work no problem

420 mA is the RATE at which it charges, (car analogy - when filling your gas tank, it's how FAST the gas flows into the tank). 650 mAh is the CAPACITY of the battery, (car analogy - it's how BIG your gas tank is).

500 mA is the RATE at which your computer USB port can give out electrons. As long as the charger isn't trying to "pull" more current then the USB port can provide, your computer will be fine.

So, short version, YES, you can use your charger with your computer, and YES, it will charge your 650 mAh battery fully.
