Can someone help me with information on buying USB chargers?
I have several devices (including a small cordless vacuum) that I need to buy USB chargers for. I've done some reading online including an article on Extreme Tech, but it didn't help me as far as making a purchase.
It looks like most USB chargers are standardized now. Is that correct? All my products were purchased within the last year, so I don't have anything older than that to worry about.
If they are standardized, there seem to still be so many varieties. I can buy 8 pin, 4 pin, 3 in 1 8 pin. They're all over the place. Plus, most listings mention a specific brand that the chargers work with say...HTC Droid or Blackberry. Does it really matter or can the chargers be used with any brand?
I want to purchase wall chargers as well as the type where you can charge from your computer and want to buy quite a few to have around, so I want to make sure I'm buying the right ones.
One last question. Are there brands that will charge faster than others?
Thanks for your help.
