FL-FB048 Fast Charge 20000mAh Power Bank
20000mAh with 18W in and 22.5W out in a 28mm body
FL-FB048 is the workhorse of the range: 20000mAh, 2.1A/18W input and 2.1A/22.5W output, in a 143 x 68 x 28mm body finished in White or Black.
The combination matters. A large pack that only accepts a slow input takes most of a night to refill, which makes it useless on a two-day trip. At 18W in and 22.5W out this one keeps up with the way people actually travel.
What This Model Does Better
Two days between wall sockets
20000mAh covers a long-haul flight, a festival weekend or a full trade-show day for several devices.
18W input, so it refills in hours not overnight
The reason large packs get abandoned is slow recharging. This one does not have that problem.
22.5W output
Enough for a modern phone to take a useful charge in a short break.
Neutral White or Black
A conservative finish that suits corporate branding and retail alike.
