UNI-T UT71E multimeter has power measurement function and bundled with power measurement adapter having AC socket. It is able to store data into internal memory but have space for 100 measurements only. So, it is not very useful...
Exactly this model was my main DMM till now and I also have power measurement adapter with AC socket (I use it for immediate power measurement, not for logging)

Nice trends. BTW, I can't wire my main DMM for logging, because I use it regularly. I need a dedicated logger, not a chain of devices.
However, now I feel deserved a DMM of more serious manufacturer

Nothing bad about UT71E (good resolution, ruggedness, sleek design, versatility, fast on, acceptable battery usage, many many years of reliable work), just hoping to get some upgrade from new instrument (Fluke? Metra Hit?). Especially I expect fast continuity detection (UT71E, Fluke 75 II are very unacceptably slow in this, totally unusable when tracing multilayer PCBs). I keep otherwise crappy Mastech MY-64 especially for this purpose, it beeps instantly, without any lag - super.
