The INIU power bank is quite compact for its capacity, measuring 5.3″x2.8″x1″. It is also one of the lighter 20,000mAh power banks, weighing in at 12.8 ounces. The power bank has three ports: two USB Type-A ports and one USB Type-C port. The USB Type-C ports are both input and output and have a maximum charging capacity of 22.5W. The Nintendo Switch supports a maximum charging speed of 18W, so this power bank will charge your Switch in the shortest amount of time possible. The 20,000mAh capacity will charge your Nintendo Switch about 2.8 times, even after factoring in 60% charging efficiency. This should be enough for all but the longest of trips. It is worth mentioning that the INIU power bank also has a small LED flashlight for emergencies.
INIU Power Bank is TSA approved
Spare lithium-ion and lithium-metal batteries, including power banks and cell phone battery charging cases, must be carried in carry-on luggage only. Power banks must have a capacity of less than 27,000 mAh or 100 Wh. This INIU power bank has a battery capacity of 20,000 mAh, which is well below the TSA limit of 27,000 mAh, so you can take it on board a plane without worry. This power bank is small and discreet enough that it’s hard to imagine the TSA even noticing it.
