The timer that makes any charger smart. Whether it's an e-bike, portable generator, laptop, flashlight, jump starter box, portable power station, or power tools, we've all got devices that we don't use daily, but we need them to be charged and ready when the time comes. Charge-O-Matic is the answer to the age-old problem of dead (fried / overcharged / undercharged) batteries in devices that have been left plugged in 24/7. You can read it in a Popular Science article, or in your device's owner's manual, but you'll find that leaving your device continuously plugged in is a recipe for diminished battery life span and premature failure. Leaving your device unplugged is just as bad for the battery and what's worse, your device won't be charged and ready when you need it. Charge-O-Matic let's you easily, quickly, and automatically charge and maintain your devices' batteries according to manufacturer specifications for maximum life span. Set it and forget it with Charge-O-Matic. Stay prepared. Protect your investment. DID YOU KNOW? Many of the devices we rely on in emergencies don't do well when left plugged in to charge indefinitely. Charge-O-Matic keeps your most needed devices charged in a way that meets manufacturer specifications and prevents premature battery demise. Super easy to set it. Reliable so you can forget it. Plus, it's ETL certified for safety. Say goodbye to prematurely destroyed and dead batteries that result from overcharging and undercharging. How it works: Any charger (or device) that is plugged into Charge-O-Matic's outlet can be set to power-on for a user-defined period of 1 to 99 hours. After the user-defined power-on period has elapsed, Charge-O-Matic turns off the outlet (and thus the connected charger or device) for the user-defined power-off period of 1 to 99 days. Once the appropriate days of power-off period have elapsed, Charge-O-Matic repeats the power-on period and so on. By repeating this scheduled on and off routine, Charge-O-Matic keeps items ready and charged when you need them, without the battery damaging overcharge associated with leaving devices charging at all times. Simple Dual Knob Design No confusing menus or key sequences. We designed Charge-O-Matic to need no instruction manual (but we supply one just in case). Safety Certified Intertek ETL Certified and conforms to UL 60730-1:2016 Ed.5; UL 60730-2-7:2014 Ed.2+R:31Jul2014. Certified to CSA E60730-1 and E60730-2-7. Reliability through Battery Backup Power outages are no match. Whether power goes out for 1 minute or even weeks, because of its non-volatile memory, you can rest assured that Charge-O-Matic will automatically resume the routine you had set once power is restored, with no user intervention! Electric Start Generators To ensure they'll start when you need them to, most portable generators have a specific battery maintenance schedule. Generac, in their owner's manual for their XT8500EFI states that the battery should be, "Charged for 12 hours, every three months." With Charge-O-Matic, turn the hours knob to 12 hours, and the days knob to 90 days. Your generator battery maintenance schedule is done forever. Set it, forget it, and never pull a cord again. Charge-O-Matic is the smart charger for your electric start generator. Enhance E-Bike Charging Safety There are three main issues to protect against with modern lithium batteries found in today's e-bikes. 1. Permanent damage due to extended periods at low state of charge. 2. Permanent damage due to unnecessary short cycling resulting from leaving the battery on the charger too long. 3. Fire hazard due to charge system malfunction. Charge-o-matic easily and automatically protects against all of these issues. Simply plug your manufacturer supplied charging cord into Charge-o-matic. Turn the hours knob to the number that charges your battery to 100% and the days knob to 30 days. Now, your e-bike battery will never have a damaging prolonged under voltage condition because it will be recharged every 30 days; it will automatically be disconnected from AC voltage when the set hours have elapsed, minimizing chances of fire; and it will never be unnecessarily short cycling itself into shorter life span due to having an energized charger connected to it. E-bike safety, automated. Portable Power Stations LiFePO4 powered portable power stations are amazingly useful, but expensive tools. Maintain your investment by following the manufacturer's maintenance recommendations. Jackery's website FAQ says, "1. We recommend keeping the battery power above 20% when using or storing the power station regularly. 2. A fully charged battery can last for several months. However, please recharge it every 3 months to keep the battery power above 50% if you don't use it." EcoFlow's blog states, "For long-term storage, discharge the battery to 30% and charge it to 85% every three months (products that have not been charged and discharged for more than 6 months are not covered)." Charge-O-Matic makes storing your portable power station to manufacturer specs easy and automatic. If your PPS takes 5 hours to charge to manufacturer spec, set Charge-O-Matic's hour knob to 5 and the days knob to 90 days. Your PPS maintenance routine is done. Forever. Jump Starter Boxes If you've ever needed a jump start, but your jump start box was dead, you need Charge-O-Matic. Stanley recommends charging its units every 30 days. With Charge-O-Matic, turn the hours knob to 24 hours, and the days knob to 30 days. Your jump starter box maintenance schedule is done forever. Set it, forget it, and never be stranded again.
