No problem at all. Don't worry. It's ok. It won't spoils your battery easily. Cause got build in overload power cut filter inside battery. Small ampere more charging time. High ampere fast changing time.
Thanks for your reassurance. I tested to charge the camera with the powerbank and it works. If I switch on RX100 when charging, i don't see the battery icon on the LCD screen and the yellow light on the "ON" dial disappears. I guess the camera is running directly from the power of the powerbank.
Surprisingly, the 500mA power from a PC USB2.0 port is just enough for charging but not enough to 'power up' the camera. I don't have any 500mA output powerbank to test. Some RX100M2 users posted in the forum that the AC adapter has been changed to "500mA" type. I'm curious whether the slow charging is able to slightly boost up CIPA 330 shots rating of RX100 to 350 shots rating of RX100M2, or because the back-illuminated sensor is slightly more energy efficient. Another guess is that RX100M2's charging time using the 500mA type adapter will be much longer.
Now, some photo time (resize to 50%)......jpg, 28mm, ISO6400, 1/10s, 1.8, handheld (brace my elbows against the sides & with the help of tighten neckstrap for extra stability)

Please don't judge my composition etc etc, Just want to practice my handheld skill (with neckstrap) because I was used to holding a dslr. RX100 sometimes gives me slightly blurry image at 1/30 if I am not careful/ steady. I find that Panasonic LX series has much greater optical stabilization.
Glad to find that RX100 can focus pretty easily at low light and it is possible to get non-blurry handheld shot if careful. the 6400 iso shot is almost free from chroma noise, the luminance noise grain is small and fine, even better than my Canon 550D's 6400 shot (chroma noise quite intrusive), if I remember correctly. In low light, I think RX100 wide open can beat my 550D with kit lens, and quite on par with it when zoom in.
