Charge-O-Matic - The Timer That Makes Any Charger Smart. Power on for up to 99 Hours, Cycle Off for up to 99 Days, Repeats indefinitely! 30 Day Timer. 60 Day Timer. 90 Day Timer. ETL Certified.

Wish I had one of these years ago! Simple to set up and use. No more forgetting to charge batteries and they're dead or overcharging and they get ruined way too soon.

We use it to set up a charging station for batteries that don’t get used a lot but we don’t want to leave charging all the time.It feels like a made for tv item but it really does work as advertised and it has kept our array of batteries fully charged wihile minimizing fire hazards.

These things are HELLLLLA EXPENSIVE.... omg.... you can get digital fancy pants timers like this from ali-express/wish/temu and other chinese retailers, for 7.99... BUT those all need advanced programing degrees to opperate.. X_X seriously, this unit is easy no-brainer. I can 'not touch it' for 4 years, then decide to plug it in some where else, and i don't even need to read a manual to adjust and program this thing! just push the dial in to start editing, roll the dial to the hours i want it ON for. then do the same to the Other dial, to adjust the DAYS i want it OFF for! THIS IS PERFECT FOR MAINTAINING LITHIUM-ION and NMH BATTERIES! Once charged, these batteries should only receive a charge again about once a month or 2. Or if you want a more regular charge cycle because you change out LOTS of batteries regularly, well you can set it for 24h ON, 6 days OFF. and you can change your schedule for it, in like 8 seconds! without reading a stupid manual, or barely even reading the dials! its just EASY to understand out of the blue. come back to it 10 years later? no problem! its self explainitory!! not like these LCD things that are 8bucks and require a degree in electrical engineering to even read the manual for! X_X; I bought 3 of these. One for the car battery bank i keep in the garage, with all its chargers on it that keeps lead acid batteries topped off through the cold winters (12h-on/5d-off). one for my SHELF FULL of lithium ion and NMH based batteries that need to only be freshened up every 2 months (24-on/60d-off), and finally one for my regular every day use batteries (12-on,1d-off) the latter gives 36 hours off, and 12 hours on. which is about my use-level. its currently May of 2024, Electric bill prices will be higher then in recorded history. These things are going to keep all those trickel-energy-hungry transformers for all those chargers, in check, so my electric bills are lower. every stupid power brick you plug in pulls power ALL THE TIME even when you are NOT charging things! Unplug them all when not in use?? that's a chore.. this product does that chore for you. Attach a surge protector to it, so a bunch of sockets are all turning on and off when it does. Cool beans!

Works great to not overcharge golf cart batteries.

Had this product for several months now and it’s worked great. I’m able to have my battery charger hooked up to it and have it go off once every month for four hours.

Simple operation. I set the days on 3 and hours on 3. It doesn’t appear to change. I thought it would indicate a countdown.

Absolutly perfect and deos exactly what you want it to do. I have a plug strip plugged into this and all my power tools, and rechargeable connected to the power strip. i have mine set to mine batteries need. it turns on every 30 days and stays on for 24hrs then kills power, and then just repeats! I bought a second one for inside for the retro handheld gaming systems and drone batteries

Look for a sticker over the display… remove it before anything else. Support was fantastic. The unit is great and should prolong my scooter batteries life.
