The battery can be fully recharged in 90 minutes.
It can charge your mobile devices up to 4 times.
It can run the blanket for 10 hours on the low-heat setting, 6 hours on medium-heat, and 4 hours on high-heat.
I have another 12V battery pack/power bank - can I use it to power the Puffe-?
Yes and no. The blanket requires a 12V power source, and a 12V battery pack would provide enough power, but you'd need the correct adapter to accommodate the barrel size of the Puffe-. The Puffe-'s plug has a 6mm diameter with a 1.5mm pin, so as long as that fits into your battery pack, you're good to go! If the power bank has an A/C outlet, then no need to worry about barrel size because the Rumpl's A/C adapter will work!
