Some portable chargers can not only charge your smartphone but can also capably charge the newer MacBooks that have Thunderbolt ports, as well as the Nintendo Switch. Those internal batteries can be one of two types: Lithium-ion (usually listed as Li-Ion) or the less common lithium polymer (Li-Po).
