Canon Pocketronic II Charger CH-1 - Karl-Ludwig Butte - 07-23-2023 04:38 PM Dear All, I was able to purchase a Pocketronic II, unfortunately without a power supply. Does anyone know how the plug of the associated power supply Canon CH-1 is assigned? Is the positive pole on the pin in the middle or outside? Every hint is welcome - thank you in advance. Best regards Karl RE: Canon Pocketronic II Charger CH-1 - Jeff_Birt - 07-23-2023 06:49 PM The manual says the charger model number is CH-1: http://www.datamath.net/Manuals_Others/Pocketronic-II_US.pdf TIP: Look on eBay for pictures: https://www.ebay.com/itm/223694211680 It is 15V center negative. Keep in mind that this will be an unregulated supply which will put out ~19V with no load. Charging the batteries will load the supply dropping the voltage to ~15V. Given that the guys above is selling NOS charges for $4 that might not be a bad option if you care in USA. RE: Canon Pocketronic II Charger CH-1 - Karl-Ludwig Butte - 07-24-2023 08:35 AM Hi Jeff, thanks a lot for your reply. The photo in the auction is a good hint, but the type of the charger is "CH-1A". What is the difference between the types "CH-1" and "CH-1A"? Thank you very much in advance. Best regards Karl RE: Canon Pocketronic II Charger CH-1 - Jeff_Birt - 07-24-2023 01:00 PM Go to eBay and search for "Canon charger CH-1", compare the pictures. This will answer your question. |
