Panasonic Gum-type Battery Charger RFEB109 Tested for Power, Junk for Safety

This is the RFEB109 charger for Panasonic gumstick batteries.

I have confirmed that it powers on with a tester, but I am listing it as junk because there was a previous incident where a gumstick battery charger, due to either the battery's condition or a defect in the charger itself (it's unclear which), was unable to actually charge the battery.
As this is being sold as junk, please consider it with the understanding that its operation cannot be guaranteed.

Shipping is planned via YuYu Mercari便 (Yu-Packet Post or Yu-Packet Post mini), but depending on packaging, it may be changed to RakuRaku Mercari便.
I aim to ship within 24 hours of purchase, but if there is a delay, I will contact you again.

Thank you for looking.
