Keywords for non-melting/exploiding/fire-causing AC/DC adapters?

Feather-light AC/DC adapters dropping from China, and I have used a few here and there.

Are there key words that can be searched for so you get a proper power AC/DC adapter, with a transformer?

How do YOU find the correct barrel-connector size w/no Radio Shacks in the area? Calipers?

My USB 2.0 Staples hub was falling apart, and not staying on it's base after years of abuse. So... I got one of the fancy, cheap, USB 3.0 7-port hubs with switches on each port, and a fancy blue LED clearly identifying if the port is on or off, and the adapter felt about empty. I used the staples adapter (2.6A, vs the 1A that came with the new adapter), as I was scared to use the one that came with it, but it got me thinking... what do other people do, use the China adapters?

Yep, you need to measure the diameter. Or buy one from Amazon that has multiple adapters. The only thing you can do is go by the star ratings by users.

As for the USB wall wart the more amps the better. 1a is a little low for a 7 port hub although it depends on what devices you plug into the hub.
