Make your WonderSwan Flat! Gum Battery Box - Color: White

This is a battery box that allows you to use gum batteries with the WonderSwan, WonderSwan Color, and Swan Crystal.
Compared to using dry batteries, the main unit becomes flatter and easier to hold. This is especially effective when using vertical screen software.
The battery life is approximately 3 to 2.5 hours with the WonderSwan Color main unit equipped with an IPS modification. (This may vary depending on the environment, such as the condition of the batteries.)

Notes:
In addition to this product, you will need gum batteries and a charger for gum batteries to use it.
Do not use the WonderSwan dedicated charger. If you charge the gum batteries while they are in the box, the battery box may deform due to heat generated during charging.
As this product is made using a 3D printer, there may be individual differences, making it difficult to attach to the WonderSwan main unit.
This listing is for the battery box only. Gum batteries, WonderSwan main unit, etc. are not included.
