Respectfully, it's not the volts - they are all 5V per USB 2.0 specification. PT's draw higher current, between 1.5 and 2 Amps depending on the resistance of the cartos (in the case of V4L, premium and wow carts are lower resistance than the cool carts and subsequently draw up to 2 A during use). There are a zillion "AC to USB" charging adapters, but many only put out 0.5 A as they only need to trickle charge ipods and phones, etc. This adapter sold by Amazon: Amazon.com: IPAD-2USB: High Power Slim AC Wall Plug to 2 x 5V USB Adapter (Compatible with iPad): Electronics is an example of one rated for "high power" use, and states up to 2 A draw on the power supply.

Basically, anything advertised to work with the iPad will probably work, as it requires a higher current USB port. Another good option is a multi-port high power USB hub - especially if you can use the other ports to power other USB devices such as external hard drives, printers, etc. at your work desk / computer station. Google / search Amazon, you will find a lot of options - don't buy it if it doesn't specify the Amperage though.

Walmart.com: Search Results for "powerline 1300 ma adapter"

Is this one what you are talking about Jam? I don't know jack about MaH or voltage!
This is what I have and all I know is that it works. Sorry If I confused the issue.

The one you have is rated at 1300 mA (milliamp) or 1.3 A; this is usually the minimum current rating, yours obviously works although the rating is on the low side for this application. Another one with the same rating might not work, which is why it is safer to go with something rated at 2 A as it will certainly provide the necessary current to power a PT with a low resistance premium or wow carto attached.

In simple terms, V = I x R where V is voltage, I is current (in Amperes) and R is resistance (in Ohms). For USB pass throughs and anything operating at 5 Volts, a wow cart with internal resistance of 2.9 Ohms, 1.72 Amperes of current will be demanded of the power source. For a cool cart with internal resistance of 3.6 Ohms, the current draw would be 1.39 Amperes.

The specs are perfect and the price is great on the one you are referencing from walmart - 2000 mA (2A) and 10W of power. I would definitely buy the iQ one posted by markfm over the one Mary Kay uses (hers is only rated for 1300 mA or 1.3 A, which is 1.5x less power output). This will insure the power adapter won't get hot reducing chance of burnout and failure as well.
