The read
What's actually worth knowing.
- It has six output ports, so you can charge your phone, tablet, earbuds, and smartwatch all at the same time instead of picking which device gets power first.
- The digital display shows your exact battery percentage from 0 to 100 percent, which is more useful than the basic light indicators on cheaper power banks.
- At 77Wh, it's under the 100Wh airline limit for carry-on bags, though you need to pack it in your carry-on only, not checked luggage.
As of Aug 14, the charmast 20000mAh Portable Charger with Built in is a good price at $35.99 — versus a $37.64 typical price and a $28.49 12-month low, based on Amazon's own price history.
