This is a set of compatible AC adapters that can be used in the same way as the AC adapters (NEC PAD-129 and PAD-130) for the PC Engine Duo-R and Duo-RX.

(Most other sellers' products do not have PSE certification) The specifications are as follows: Compatible models: PC Engine Duo-R and Duo-RX (PC Engine Duo is not supported) Included items: AC adapter (9V/2A, PSE certified) and plug adapter (All included items are new and have only been tested for operation) How to use: ① Plug the AC adapter into the wall outlet. ② Plug the DC plug of the AC adapter into the DC jack of the PC Engine Duo-R or Duo-RX. ③ Turn on the PC Engine Duo-R or Duo-RX. ※① and ② do not have to be in order. ※Although the DC plug may physically connect to game consoles other than the PC Engine Duo-R/Duo-RX, please never use it with game consoles other than the PC Engine Duo-R/Duo-RX. The game console may be damaged due to differences in voltage or polarity. In addition, this product can be returned if it does not power on.
