Charmast 20,000mAh Power Bank — Four Built-in Cables, Five Outputs! $36.99 CAD (38% Off)

Amazon.ca has the Charmast 20,000mAh power bank with built-in cables for $36.99 CAD (list $59.99, 38% off). Free shipping for Prime members; otherwise free on orders over $35.

Three cables live inside the body — Lightning, USB-C and Micro USB — plus two USB-A ports, so it can feed five devices at once with up to 22.5W on a single port. That's roughly four to five phone charges, or a couple of tablet top-ups. No more digging through your bag for a cable at the airport gate or on a train. The 20,000mAh capacity is carry-on legal, but it can't go in checked luggage.

At 340 g and 1.9 cm thick it slides into a coat pocket without a bulge. The front panel is a proper LED display showing the exact percentage, not four vague bars. Low-current devices like earbuds and watches work too — hold the power button for five to ten seconds until the digits start cycling.

One thing to plan around: recharging the pack itself is slow. About six hours through USB-C, twelve hours if you use the built-in USB-A cable. Plug it in overnight and grab it in the morning and it's fine.

20,000mAh, six outputs, three built-in cables — the price is low for that combination. 4.5 stars across 8,500+ reviews and ranked sixth in its category, so it isn't an unknown badge brand.
