The DPAs need a bit higher voltage than the usual plug-in-power recorders provide. A battery box that provides at least 5V should work, with a cable that takes microdot to a stereo 3.5mm plug. Church Audio made me a battery box (standard 9V cell) that takes two microdot inputs and provides a stereo 3.5mm output for many portable recorders. The Sony D100 (among its many nice features) will power the DPAs, and the Deity PR-2 announced last April (and still vaporware) is supposed to have switchable 3/5V power; both these will need a microdot-to-3.5mm cable (I have verified that the D100 works fine with this, but I have not made many recordings with it).
Or you can go for the DPA4063, which is an omni with lower plug-in-power requirements.
In case others missed it, I want to emphasize that Jeff had a
custom powering module built for him for his DPAs. The reason I call attention to this is that you don't want to just plug them into any power supply within 9V battery, because if they are actually fed 9V or higher, you risk damaging them.
Jon at Naiant Studio can make you custom PFAs for these mics, although I'm not sure he can do microdot connectors. My 4061's came with TA4 termination so Jon was able to make me PFAs to match. Note that this would be only applicable if connecting to a recorder with 48V phantom powered XLR inputs. If you have microdot termination, you would have to use DPA's own XLR adapters in this situation.
One other thing that hasn't been mentioned about the DPA lavs is their moisture resistance. They are made to withstand being sweat upon by stage actors. There used to be a video on DPA's website where a guy goes wading into a lake wearing one, and while the audio cuts out while the capsule is immersed, the mic is totally fine afterwards. The official way to clean them is to swish them around in a glass of distilled water.
