Recommendations for small battery pack to use as cache battery? I’ve got a sinewave revolution wired to an SP hub, but the 6700mah Ravpower battery pack I have ain’t charging properly. The setup charges my phone absolutely fine (25% to full in 2 hours) but it’s getting nowhere with the battery pack. The sinewave unit does seem to heat up more charging the battery pack than the phone, not sure what’s going on.
