Nintendo sold more than 3.5 million units of its flagship Switch 2 gaming system in the four days following its launch, with online stores of major U.S. retailers putting up “out of stock” signs.

The Anker Nano Power Bank has a built-in USB-C cable, so if you forget to bring one, you can still charge your Switch 2 without having to scrounge for a spare. At 10,000mAh, you should be able to get at least one full charge out of it, which is pretty great considering how small and compact it is (4.09 × 2.06 × 1.02 inches).

Nintendo Co.'s Switch 2's record-breaking launch signals strong demand, but high expectations are already priced into the stock. Find out why NTDOY is a Hold.
