Chargers - Can we mix and match?

[Chaznsc]

I'm wondering if you can (or should) use a charger for say an iPad to charge the Droid X or Kindle Fire, or perhaps other models?

• Kindle Fire Charger - Output=5w/1.8a
• DroidX Charger Output=5.1V/850mA (I think)
• iPad Charger - Output=5v/1a

I'm an electricity idiot so none of the numbers register with me. Im just so tired of dragging along this wad of chargers for everything I own.

I would recommend against using a charger that was rated higher than the stock charger. Using the charger for the Kindle Fire could damage the DroidX, while the DroidX charger will take forever to charge the Fire.

Are you sure you're reading that Kindle Fire charger correctly? 5w / 1.8a = 2.7 volts. Most consumer electronics are designed to work with USB ports for charging, which is 4.5v-5.1v. 2.7v just seems really low. Most LiIon batteries operate from 3.5v to 4.3v. 2.7v just wouldn't cut it to charge the LiIon battery, regardless of the current rating.

Otherwise the Droid X charger is the safest. But it may not be safe for the Kindle Fire, due to the voltage difference.

I think he meant 5v/1.8a.

Hopefully, but you never know Amazon might have done something weird with transformers.
