If your adapter puts out .5 amps and your PT needs 1.5 amps you're likely to have a problem since there's not enough current. If your adapter puts out 2 amps and you only need 1.5 you have some extra that doesn't get used and it's ok.
It's kind of like a water faucet. You can turn it on full blast, but you don't always have to. You don't want to turn it all the way on to get a small cup of water, but to fill a bathtub that takes a lot more water you put it as high as it'll go. I hope this analogy makes sense?
Okay folks, here is what I bought: (2 things)
#1:
A wall adaptor that has 4 USB ports.
On the back it says:
DC Output: 5V / 2A
AC Input: 100V - 240V
50/60Hz 280mA
The insert for the AC to USB says this:
Allows you to charge up to 4 devices.
Short Circuit protection and overload protection.
Indicator light: Lights when power is connected. Blinks when overload.
NOTES:
Using one port yields the full 2000mA, two ports yields 1000mA per port, and all 4 ports yields 500mA per port.
#2:
A car cigarette plug that has 1 USB port, 1 plug for an electrical plug, and 1 plug for a cigarette-type plug.
On the back it says:
12VDC to 115VAC Power Inverter
Input: 12VDC Nominal, 11-16VDC range
Output: 115VAC/150 W continuous
Peak Power: 300 W
USB Output: 5VDC 500mA (max)
So, if I understand everyone correctly, the AC to USB will be able to charge 4 Riva/eGo batteries all at once.
But it will only power the eGo passthrough if it is plugged in by itself OR with just one Riva/eGo battery.
For the cigarette plug:
I can charge a Riva/eGo battery but NOT charge the passthrough (because it only will power 500mA and the passthrough needs at least 550mA)
Am I correct?????????
If so ... here's a question:
Could I plug in my AC to USB adapter (that normally goes into a wall outlet) into the electrical plug on the cigarette plug adapter and THEN plug the passthrough into that?
