eGO MEGA Car charger mah ratings

[nateb4s5]

Does different rating mah car chargers ratings make a difference for my eGO 900mah batteries health? Can I just use any ego car battery charger? Can I get the higher rating mah charger?

Thanks

The mah and amps rating tell you how much power is allowed to flow through each separate piece. (car adaptor, ego charger, etc) They wont really make a difference on the health, just speed of charge, unless your talking about buying something not made for e cigs. As long as you stick to e cig related items, or vendors, you should be fine regardless. 900 mah ego just has higher capacity than 650, not more power.

You should look for a USB adapter that supplies at least 1 amp. This could be list as 1A or 1000mA, mah is short for milliamp hour and is used to measure batter life. When matching power adapter to device you always need to match the voltage and supply at least the same amperage as the device, higher amperage is fine. The amp listing on the power supply is the max it can produce, the device will only pull what it needs.

the time to charge is longer the higher the mAh of your battery and shorter the higher the mA of the charger, BUT this is where cheap parts or things not made specifically for your system can get you into trouble. for charging a battery, a USB rated at 500 mA max should be safe (some units have two ports with 1000 mA max, 500 mA average), 1000 mA should not be a problem as long as you use the chargers supplied (it hasn't been for me), and 2000 mA is what you need for a "pass through" (and I am personally not comfortable charging my batts with one). when you buy USB power adapters, you get what you pay for (and sometimes more mA than you bargained for). Kensington is a well respected brand (stick to brand name parts).

You don't need to worry about higher. The alternator in your car can produce from 60 to 130 amp at 12 volts. The power port delivers 12 volts and has a 15 or 20 amp fuse, so when you plug in an adapter that pulls .5A, 500Ma, it doesn't matter that the port can supply 20amps before blowing the fuse since only .5A is pulled. A USB adapter changes the 12 volts to 5, and can only produce a maximum amount of amps at 5 volts. So putting a 2A USB adapter in and plugging in a device into that USB adapter that only draws .8A is no problem, just like the USB adapter only pulling a max 2A on a 20Amp circuit is no problem.

The problem is when a device tries to pull more amperage than the adapter can produce a cheap adapter can overheat and burnout.

Adapters listed as good for an iPhone 4 should be 1A and for an iPad should 2A. I use iPad type compatible adapters.

Thought you might like to know that Overstock has these available now for under $12....plus shipping, so under $15 for the iPad type.

I bought a 2A USB adapter for the car just to have a backup in case of a winter power failure. You never know!

Your charger only uses power in relation to the load it places on the power source. That's why a 60 watt bulb uses less power than a 100 watt bulb. It's all about resistance and reactance. Reactance is an inductive power rating that is analogous to DC resistance.

Your DC USB adapter in the car won't pull any more power than the device you are charging with it. As long as it is rated above the device you are charging, you are fine.
