Follow-up Review: Killed it. 07/07/2012
This review is from: TP-LINK TL-WR702N Wireless N150 Travel Router, Nano Size, Multifunction, 150Mbps
Well, everything I said above still stands....
WARNING on flakey USB power sources! May kill the router!
Managed to kill it with a bad usb power supply.
Plugged in an *authentic* ipod power wart (A1265) that I guess was a little leaky and it fried the router.
This is the same charger that I charge my iphone with!
Guess the iphone has better power filtering and can better tolerate the flakey supply.
Got me curious as to what kind of power protection the router has on its usb power input. So I took it apart (I'm an EE). With the help of a very powerful magnifying glass, it seems that the first device the power see's is a charge-pump/buck regulator and tiny coil to drop the voltage. This let the evil voltages past and shorted something downstream (cap?).
Doesn't appear to have any active filtering/power protection device -- hmmm.
A consumer device that powers off of USB should have power protection. You never know what someone will plug into it. For what its worth, the USB power spec (for outgoing power) requires such circuitry in case someone plugs in something bad.
My iphone seems to be protected as the bad supply didn't kill it.
Obviously since I did a router autopsy, I cannot return it under warranty. So chalk it up to a learning experience.
Stick to the provided power adapter or use a proper USB port on your computer and you shouldn't have the same problem
