For anyone interested, I've had an ammeter across the DT's DC input, to check the actual current requirements during use...
- When switched on, the bootup peaks at around 900mA (0.9A) for a few seconds
- During use the DT is using 425-500mA (0.5A)
- Switching patterns raises to ~550mA
- Measured with headphones attached, turning the volume up to max does not seem to affect the mA
Online battery life calcs give an estimated 12hrs use from a 10,000mAh battery @600mA
At the AC socket (UK) end, the usage is ~5.5-6.5W @240VAC during normal playback, ~10W during bootup.
As @Joshua ^^ above says, using the supplied AC power adaptor connected to an inverter is the safest method, and also retains the product warranty!
Using a 12V DC powerbank connected directly should be pretty safe though, the Elektron power supply (UK) outputs a steady 12.17VDC (@240VAC PSU input).
Using 5V-12V conversion adaptors might result in problems, the DT seems pretty sensitive to its DC supply, I experienced reboots and crashing merely by introducing measuring cables.
An Elektron Battery Bank Slanty Stand would be awesome tho...
