    I only plug mine into the wall

    and into the car lighter socket

    I don't think a $20 battery is worth risking my laptop or anything other that mentioned above.... IMO

    I don't know about TV usb ports, I do know that using the charger in cars power port is not recommended, my understanding is the power ports aren't very well regulated in many cars.

    I have also read the using a computers usb port can be hard on the computer, it may tax the power supply. The TV may not like the draw the Ego places on it, wall warts are the recommended way to go. That being said, I have used my computer with a passthrough many times, but I have a rather large rated power supply.

    Powered USB port 5vdc 500ma....anything that produces that or greater will power the charger..the chargers output is 4.2vdc at 420ma REGULATED

    Most computer USB ports now a days are rated at 1000ma or higher

    On the side: Have charged with a laptop, no problem. It even charges when off, but plugged in.

    The USB port only provides power to the charger, at 5 volts. So it should not hurt the battery.

    Like many others, I use a wall wart / adapter for my charging. My computer's health is more important than the convenience of plugging in there. While it's usually fine, one faulty charger could make for a very expensive charge!

    Even if a usb port is poorly regulated it would probly never cause any issues. The charger is itself a regulator. Regulating from 5V to 4.2V. Most regulators have a relativley large input voltage range from say 3.0V to 18V with input needing to be +.5V of output voltage. I would argue that a cheap battery charger is more likely to damage the USB source or the battery then the source damage the battery or charger.

    A couple of years ago, I bought a Duracell two-port USB wall wart. I think I got it at either Office Depot or Office Max. I can charge two Ego batteries at once. The wall wart is absolutely the safest option. The Duracell two-port wart is just another layer of safety.

    if you over-drain an usb port, it will simply shut down the unit until you restart the device, in any case usb chargers are mostly 500mAh anyway which is what standard usb2 ports are officially rated for. Those ego chargers are rather crappily regulated and will sway in voltage depending on the input, my building has 236v for example (euro standard is 220-240) which makes your average wall plug ego charger overcharge the battery. USB ports are much more stable, the standard specifies 5% max deviation whether its a computer or a car.
