Estimated runtime

Estimated runtime = capacity × usable fraction ÷ average load. We assume a usable fraction of 0.75–0.85 to allow for conversion losses; this is an assumption, not a measured value.

Average loadEstimated runtime
50 W4.2 h – 4.8 h
100 W2.1 h – 2.4 h
300 W0.7 h – 0.8 h
500 W0.4 h – 0.4 h
