## Overview

The Charge-O-Matic is a versatile digital timer that transforms any charger into a smart device by enabling programmable power cycles up to 99 hours ON and 99 days OFF. Designed to prevent battery damage from overcharging, it features a backup battery to retain settings during outages and is ETL certified for safety. Ideal for electric start generators, power tools, and USB devices, it offers professional-grade automation that frees you from manual charging routines.

## Description

The Charge-O-MaticTM is a simple to use device that solves the age-old problem of powering and/or charging devices that need to be periodically charged or powered for several hours, but then need to remain unpowered for many days to avoid overcharging and damaging batteries. Example use cases include electric start backup generator batteries, electronic devices that are infrequently used, power tools and more. There have been many commercially available timers on the market, but typically these devices are limited to an powered-on duration of only 24 hours, at an interval period of 7 days. The Charge-O-MaticTM allows powered-on durations of much longer, up to 99 hours–at intervals of anywhere between 1 and 99 days. For example: Generator producer Generac explains on their website, “The customer should charge the battery at least once a month for 24-48 hours in preparation for usage... The charger should be connected for no longer than 48 hours.” Most customers do not remember to charge and unplug their generator batteries monthly. Inevitably, they leave the batteries connected to the charger indefinitely, damaging the battery, and leaving them with a dead battery when it is time to use the generator. With the generator’s charging cord plugged into the Charge-O-MaticTM, the customer could set the Powered On Duration period to 48 hours and the Days Between On Cycle to 30 days. The timer would then power-on for 48 hours and then power itself off for 30 days, at which point it would again power-on for 48 hours, and then again power off for 30 days and so on, indefinitely. No more remembering to plug and unplug devices. While this is one use-case, the Charge-O-MaticTM can be used for any device that would benefit from power cycles at intervals. If you're looking for a 30 day timer, this is it, except it can go up to 99 days!
