Jackery Explorer 100 31,000mAh Power Bank for $99.99

At first glance the Jackery Explorer 100 looks like one of those large power stations you might use as a backup battery for your home. But actually, this thing is pretty small, small enough to fit on the palm of your hand. It measures only 5"x3.4"x3.4" and weighs about 2 pounds. This is a 99Whr power bank, which means it just barely squeezes its way under TSA's sub-100Whr requirement. With a 31,000mAh total capacity, this is definitely the largest TSA carry-on eligible power bank we've posted on IGN.

Unlike most smaller power banks which use lithium-ion cells, the Jackery Explorer 100 uses LiFePO4 cells. They're usually more expensive and also a bit heavier, but in exchange you get inherently safer battery chemistry and a much longer lifespan, both in terms of number of cycles and calendar aging.

The Jackery Explorer 100 has three outputs: two USB Type-C with PPS and Power Delivery up to 100W total, and a USB Type-A with 28W of charging for a total of 128W. The Steam Deck supports up to 45W max charging, the ASUS ROG Ally up to 65W, and the Nintendo Switch up to 18W. That means ou can charge a Steam Deck, ASUS ROG Ally, or Nintendo Switch at its maximum charging speed. In fact, you could almost charge all three at their maximum charging rate simultaneously.

Jackery is a well known brand that's based out of Fremont, California. They're very reliable and are often a great alternative to the juggernaut Chinese companies like Ecoflow and Bluetti. This power bank is UL 94V-0 certified and includes a 2 year warranty.
