Another unfortunate blip in Nintendo Switch’s accessory nightmare, the bundle Joy-Con Grip will be different than the Joy-Con Charging Grip. The main difference is in the name — the standard Joy-Con Grip bundled with Nintendo Switch won’t be able to charge the Joy-Con controllers on the go.
Whether this is a problem depends on how you plan on using your console. According to the Joy-Con controller’s product description, battery life is expected to be around 20 hours (conceivably four times the battery life of the Nintendo Switch itself). Additionally, docking your Nintendo Switch to play it on the TV will require charged controllers. So if you see yourself going 20 hours in docked or tabletop mode without taking time to charge, investing in the Charging Grip is in your future.
However, if you want to be able to charge the Joy-Con controllers on the go, it requires sinking $29.99 into the premium accessory. Nintendo Switch (and all its accessories) launch on March 3, 2017.
