Here's a quick look at the new Vari-Volt cable from IndiPro Tools. This is a handy cable to have in the tool bag, especially if you own several of these V-Mount style batteries. This voltage converter with female P-Tap typically runs for $120+ (as seen here).
The Vari-volt is a voltage regulating powertap cable capable of converting an input voltage between 12-18v to a chosen constant voltage of 5v, 7.2v, or 12v. The cable's regulator box has a 2.5 x 5.5mm dc input, as well as an inline female powertap. The cable also includes a 24" 2.5 x 5.5mm to 2.5 x 5.5mm extension cable. The regulator supplies up to 3A of current.
Today, IndiPro Tools is sponsoring a product giveaway for one of these cables. You can register for the IndiPro Tools Vari-Volt product giveaway following the link (found here).
Vari-Volt with Female D tap
@Dave - If I understand the question correctly, it's really based on what you're connecting to it. The accessory will determine how much it needs to draw, but you can only connect accessories that draw up to 3A.
Do you know if this still drains the same amount of power as well? Or is the amperage draw still the same from the v-mount?
If your a DIY'er seems like alot of money for something so simple. For $5 you can buy a variable voltage converter off ebay. https://www.ebay.com/itm/LM2596-DC-Power-Supply-Adjustable-Converter-Step-Down-Module-LED-Voltmeter-USB-/141082066753?pt=LH_DefaultDomain_0&hash=item20d9257f41
