The ZMI PowerPack No. 20

(Model QB826G) is the

closest thing I’ve seen in

many years to the kind of

outboard laptop battery popular in the

days when batteries burned through

stored energy as quickly as sparklers. The

PowerPack No. 20’s prosaic name hides

its massive output: up to 210 watts across

three output ports simultaneously!

The name also undersells this sleek,

surprisingly dense gray and black lithium-

ion power pack, which has ports just on

one end to access the 90 watt-hour

(Wh)/25,000 milliampere-hour (mAh)
