Charge-O-Matic TM - Smart Battery Charger Timer

What Charge-O-Matic™ Is (and Isn’t)

Charge-O-Matic™ is not a battery charger. It’s a patented smart timer that controls the charger you already own. It cycles power on/off automatically to keep batteries healthy without overcharging.

Compatibility: Your charger must begin charging when power is applied. If it needs a button press or mode selection at power-up, it is not compatible.

Patented, One-of-a-Kind Technology

Charge-O-Matic™ is the only product of its kind, backed by U.S. Patent 11,610,749. It delivers long-interval maintenance cycles no smart plug or basic timer can match.

Why Use a Battery Charger Timer Switch?

• Extend battery life: avoid constant trickle charging
• Automate maintenance: set hours ON / days OFF
• Multi-use: e-bikes, generators, jump starters, scooters, tools
• Multi-device: use a power strip if all share one schedule

Why Not Just Use a Smart Plug?

• True long OFF cycles: hours ON, then days/weeks OFF, repeat
• No Wi-Fi/app: simple dual-knob controls—set and forget
• Resumes after outages: backup memory continues the cycle
• ETL certified: purpose-built and safety tested

Smart Plug Myth vs. Charge-O-Matic Reality

Some smart plugs can do daily/weekly schedules. Long-term battery care requires running occasionally, then resting for weeks—not daily toggles.

• Smart plugs: clock-based daily/weekly, lose schedules on glitches
• Charge-O-Matic: set 1–99 hours ON and up to 99 days OFF
• Right intervals: 30 / 45 / 60 / 99-day rests for safe storage

Bottom line: Smart plugs are for lamps and kettles—Charge-O-Matic™ is engineered for batteries.

Automatic Battery Maintainer for Storage

Run your charger for a few hours, then rest for days. Repeat indefinitely for seasonal gear, stored vehicles, generators, and more.

• On Time: 1–99 hours
• Off Time: 1–99 days
• Standby draw: 0.4W
• Outage-proof: resumes where it left off

Charger Compatibility Examples (not exhaustive)

Works with chargers that auto-start on power:

• Trickle/float: Battery Tender Jr., Schumacher, NOCO (auto-start)
• Power tools: Milwaukee M18, DeWalt 20V, Makita LXT (plug-and-charge)
• Generator/RV: standard 12V maintainers for starter batteries
• E-bikes: Rad Power, Aventon, Lectric, Juiced auto-start chargers
