P ower­bricks pack­ing a large charge aren’t un­usual, but for a 20,000mAh de­vice to be as small as the ChargeUp cer­tainly is no­table. It comes in at 136 x 71 x 28mm, which is about half the size of a typ­i­cal 10,000 mAh pow­er­pack. So, yes – twice the charge, half the size. That’s nice. It isn’t light, weigh­ing in at 380g, but that’s to be ex­pected.

Its power to size ežciency comes via the use of lithium poly­mer bat­ter­ies. 20,000 mAh is mighty use­ful for ex­tended trips away from civ­i­liza­tion or con­ve­nient charg­ing points. That ca­pac­ity rep­re­sents about six full recharges for a cur­rent smart­phone, and at least one full recharge for most lap­tops.

Two USB ports al­low 2.4 Amp si­mul­ta­ne­ous charg­ing, or sin­gle port charg­ing at 4.8 Amps.
