Review on SLENPET 20000MAh Rechargeable Operated 350°Rotation by Jason Ballard

Pretty decent! Especially when combined with a portable foldable 20-30W USB panel! Not sure if 20 amps is valid, not tested for memory leaks! I believe the fin blades are 5-6 inches! It seems to last over 12 hours at full speed, not sure I've read the specs! For me living in a van this is great! Definitely not a box fan (which draws around 25-50 watts), but given a 20 amp x 3.3 volt battery (lithium polymer is typically rated at 3.3 volts) and the polymer has one 6 times the service life compared to ions! When I turned off the battery and tried to start it from the death charge, it only uses the lowest speed - (which I understand about lithium, charging is acceptable to me)! A short loading time later allowed full speed! If the polymer battery is 20 amps × 3.3, that's 66 watts! The capacity of most lithium batteries is usually overestimated by 5-10%! I would imagine 60 real watts! Does it blow at 5 watts per hour? For the price and fan, $45? Its worth it! I still love the fan! And it's just a fan! Rschunimagu.
