Tomahawk TG5500i 5500W Inverter Generator | E-Moto Charging, 120V/240V & Backup Power
Built Tough for Bigger Power Demands
The Tomahawk TG5500i Inverter Generator is the step-up option for riders, professionals, and off-grid setups that need serious portable power. With 5,000 rated watts, 5,500 starting watts, 120V and 240V output, advanced inverter technology, and less than 3% total harmonic distortion, this generator gives you substantially more room for high-output e-moto chargers, multiple bikes, tools, appliances, and other equipment.
For e-moto riders, the biggest advantage is usable continuous power. A 5,000W rated output gives you room to build a much more capable track, race, camping, or emergency charging setup without immediately running into the limits of a smaller generator.
The TG5500i is powered by a 312cc engine and carries a large 4-gallon fuel tank for up to 8 hours of runtime at half load. Eco Mode helps manage engine speed and fuel consumption as demand changes, while electric start, built-in wheels, GFCI outlets, parallel capability, USB charging, and a 62 dBA noise rating make this a versatile generator for both work and recreation.
Super Quiet Operation with Eco Mode
At a listed 62 dBA, the TG5500i is designed to keep noise more manageable than a traditional open-frame generator. That's useful when you're running power around a campsite, race pits, residential area, food truck, or other location where a loud generator gets old quickly.
Eco Mode adjusts engine speed to better match the electrical load. When your equipment doesn't require the generator's full output, the engine doesn't need to work as hard, helping reduce unnecessary fuel consumption and noise.
Up to 8 Hours of Runtime
A larger generator isn't very useful off-grid if you're constantly stopping to refuel it. The TG5500i combines its 4-gallon / 15.1-liter fuel tank with Eco Mode and efficient engine operation to provide up to 8 hours of runtime at half load.
That longer runtime is particularly useful for all-day track events, race weekends, camping trips, remote jobsites, food trucks, and emergency situations where dependable power may be needed for hours at a time.
Built-In Wheel Kit for Easier Transport
At 122 lbs, the TG5500i isn't meant to be carried around like a small 2kW generator. Instead, the built-in wheel kit makes moving the generator around the garage, shop, campsite, race pits, barn, or jobsite much easier.
The larger 25 x 22 x 28-inch platform gives you more engine, fuel capacity, and electrical output while still remaining mobile enough for portable applications.
Two USB Charging Outlets
The TG5500i includes two USB outlets for convenient charging of phones and other compatible electronics. It's a small feature that becomes pretty useful when the generator is already handling the bigger jobs like charging bikes, running tools, or keeping camp equipment powered.
GFCI, Parallel Technology & Twist-Lock Power
The TG5500i combines GFCI outlets, parallel capability, a 120V twist-lock outlet, and 240V output to support a much wider range of equipment than a basic portable generator.
If your power requirements eventually exceed a single TG5500i, its parallel capability allows compatible units to be connected for additional available output.
120V & 240V Power
The TG5500i provides two 120V outlets, one 120V twist-lock outlet, and one 240V outlet. This gives you more flexibility for higher-demand equipment and compatible charging systems.
For e-moto charging, always verify your charger's required input voltage before connecting it. Never connect a 120V-only charger to a 240V source. If your charger supports 120V and 240V input, follow the charger's manufacturer requirements for the proper connection and input voltage.
What Size Generator Do I Need for My E-Moto?
Choosing a generator for your e-moto is pretty simple: size it based on your charger, not your bike's motor. A 20kW e-moto does not need a 20,000W generator.
Quick Formula:
Charger Watts + Other Equipment + 20 to 30% Headroom = Recommended Generator Size
Example: If your e-moto charger uses 1,000W and you want another 300W available for lights, a fridge, phones, or other gear:
1,000W + 300W = 1,300W
Add about 25% headroom and you should look for roughly 1,600W or more of continuous/running output.
With 5,000W of rated continuous output, the TG5500i moves well beyond a basic single-bike charging setup. It gives you considerably more room for high-output chargers, multiple bikes, or charging while simultaneously powering your campsite, race pits, tools, or other equipment.
For sustained charging, calculate your available power using the generator's 5,000W rated output. The 5,500W starting output is intended for short startup demands and should not be treated as continuous charging capacity.
If your charger lists AC input voltage and amperage rather than watts, you can get a quick estimate using Volts x Amps = Watts. When available, use the charger's listed AC input wattage or manufacturer specifications for the most accurate number.
Charging Multiple E-Motos
This is where a 5,000W generator starts making a lot of sense for groups, families, race teams, or anyone bringing multiple bikes.
For example, two e-moto chargers drawing 1,500W each would create approximately a 3,000W continuous load. That still leaves additional rated generator capacity for compatible lights, electronics, tools, refrigeration, or other equipment.
Three 1,000W chargers would also create approximately a 3,000W load. The actual number of bikes you can charge at once depends on each charger's AC input requirements, not simply the number of outlets on the generator.
Always add the entire electrical load together and leave reasonable operating headroom rather than planning to continuously run the generator at its maximum rated capacity.
Why Inverter Power Matters
The TG5500i uses advanced inverter technology and is rated at less than 3% total harmonic distortion. This produces clean, stable power suitable for compatible e-moto chargers, computers, electronics, audio equipment, appliances, tools, and other sensitive devices.
When you're spending thousands of dollars on a bike and its battery system, power quality is worth paying attention to. That's one reason we generally prefer a quality inverter generator for e-moto charging when the generator is also going to be used with sensitive electronics.
Generator or Power Station?
Both can work. A fuel-powered generator like the TG5500i has the advantage of extended operation as long as you can refuel it, which can make more sense for multi-day riding trips, race weekends, jobsites, and emergency situations.
For portable battery power stations, check both the AC output wattage and battery capacity in Wh or kWh. Output determines whether the power station can run your charger. Capacity determines how much stored energy is available to put back into your bike, before accounting for normal conversion and charging losses.
Track, Camping & Emergency Use
If you're charging multiple e-motos or running additional equipment, add everything together. Your chargers, lights, refrigerator, tools, speakers, electronics, and other equipment all contribute to the generator's total load.
With 5,000 rated watts, inverter technology, 120V and 240V output, a 4-gallon fuel tank, and a built-in wheel kit, the TG5500i is a strong option when your setup has grown beyond simply charging one bike.
EV Charging
The TG5500i's higher output and 240V capability may make it relevant for some emergency EV charging situations, but EV charging has additional electrical, grounding, EVSE, and vehicle compatibility requirements. Having a 240V outlet does not automatically mean a generator is compatible with a Tesla or another EV.
Always verify compatibility between the generator, EVSE, vehicle, grounding requirements, outlet, and charging equipment before attempting EV charging.

Frequently Asked Questions
Frequently Asked Questions
What's the Warranty? 2 years What Size Generator Do I Need to Charge My E-Moto? Charging your electric dirt bike or e-moto from a generator or portable power station is easier than it might sound. The most important number to look at is the power draw of your bike's charger, not the peak power of the bike's motor. A 20kW e-moto does not require a 20,000W generator to charge it. Your generator only needs to supply enough power for the charger and anything else you want to run at the same time. Quick Rule: Check Your Charger Look at the specifications on your e-moto charger. If the charger lists its AC input wattage, use that number. If you only know the approximate charger output voltage and amperage, you can estimate: Volts × Amps = Watts For example: 84V × 10A = approximately 840W Because of charging and conversion losses, actual AC power draw can be somewhat higher than this estimate. When possible, use the charger's listed AC input rating for the most accurate generator sizing. We also recommend leaving additional capacity instead of continuously operating a generator at its maximum output. For an e-moto charger drawing around 840W, a generator with approximately 1,200W or more of continuous output would provide useful additional headroom. Don't Size Your Generator Based on Your Bike's Motor This is one of the most important things to understand. If your e-moto has a: 8kW motor 12kW motor 20kW motor 25kW motor that does NOT mean you need an 8,000W, 12,000W, 20,000W, or 25,000W generator. The motor's power rating tells you how much power the bike can use while riding. The charger determines how much power is required from the generator while charging. Want to Charge Your E-Moto and Run Other Equipment? If you're heading to the track, camping, traveling, or preparing for an emergency, you may want your generator to do more than charge your bike. Simply add together the approximate wattage of everything you expect to operate at the same time. Example Track or Camping Setup E-Moto Charger: 900W Portable Fridge: 100W Lights: 100W Laptop & Phones: 150W Estimated Simultaneous Load: 1,250W Instead of choosing a 1,250W generator and running it at or near maximum output, we recommend leaving some additional capacity. A generator with approximately 1,800–2,000W of continuous output would provide much more comfortable headroom for this example setup. Want to Charge Multiple E-Motos? You can do that too, as long as your generator has enough continuous output. For example: E-Moto Charger #1: 900W E-Moto Charger #2: 900W Other Equipment: 300W Total Load: 2,100W Add approximately 20–30% additional capacity and you're looking at roughly: 2,500–2,750W+ continuous generator output If you don't need to charge both bikes simultaneously, you can also charge one bike at a time and use a smaller generator. Battery Size vs. Generator Size Battery capacity and generator output are two different measurements. Your e-moto's battery capacity tells you approximately how much energy the battery can store. Your charger tells you approximately how quickly that energy needs to be supplied. Watts (W) = Power Watts tell you how much power your equipment needs at a particular moment. Watt-Hours (Wh) = Energy Watt-hours tell you how much energy a battery can store. For example, a 4,000Wh (4kWh) e-moto battery does NOT require a 4,000W generator. If the bike uses approximately a 1,000W charger, the generator only needs to comfortably support that charger's power requirements. A 4,000Wh battery being charged at approximately 1,000W could theoretically require around four hours of charging from empty, but real-world charging time will generally be longer due to charging losses, battery management, charge tapering, and other factors. What About Portable Battery Power Stations? You can also charge many e-motos using a sufficiently powerful portable battery power station. When choosing a power station, there are two important specifications to consider: 1. AC Output The power station's inverter needs to provide enough continuous AC wattage to operate your e-moto charger. 2. Battery Capacity The power station's Wh or kWh capacity determines approximately how much energy you have available to put back into your e-moto. For example: If your e-moto has a 4,000Wh battery and your portable power station stores 2,000Wh, you should NOT expect the power station to completely recharge the bike from empty. Actual energy transferred to the bike will also be lower than the power station's advertised capacity because some energy is lost through the inverter, charger, wiring, battery management system, and charging process. This is why both output wattage AND battery capacity matter when choosing a portable power station. Can I Use a Generator to Charge My E-Moto During an Emergency? Yes. A properly sized generator can be an excellent backup charging solution during power outages, emergencies, extended trips, or anywhere normal AC power isn't available. For modern e-motos and other sensitive electronics, we generally recommend a quality inverter generator with stable AC output. Always confirm that the generator's voltage, frequency, continuous output, and outlet configuration are compatible with your charger. IMPORTANT GENERATOR SAFETY Never operate a gas, propane, or other combustion-powered generator indoors, inside a garage, enclosed trailer, tent, vehicle, or other enclosed space. Generators produce carbon monoxide, which can be deadly. Always follow the generator manufacturer's operating, ventilation, fueling, grounding, maintenance, and safety instructions. Can I Charge a Tesla or Other Electric Vehicle? Potentially, but EV charging is significantly more demanding than charging most e-motos. Some properly configured generators may support emergency 120V Level 1 EV charging, while larger generators may be capable of supporting higher-output EV charging equipment. However, EV charging equipment can have specific requirements involving: Voltage Continuous amperage Generator wattage Grounding/bonding configuration Outlet type EVSE compatibility Having enough advertised watts does not automatically mean a generator will successfully charge every EV. If charging a Tesla or another full-size EV is an important part of your intended use, choose a generator specifically suited for EV charging and verify compatibility with your vehicle and charging equipment. Quick Generator Sizing Guide What You Want to Power Suggested Starting Range Small E-Moto Charger 1,000–1,500W Larger/Faster E-Moto Charger 1,500–2,500W E-Moto + Camping Equipment 2,000–3,500W Multiple E-Motos 3,000W+ E-Moto + Larger Track/RV Setup 3,500W+ EV Emergency Charging Application Dependent These are general starting points. Always check the actual power requirements of your charger and equipment before selecting a generator. Easy Generator Sizing Formula If you're trying to figure out which generator is right for you, use this simple process: STEP 1: Find the wattage or AC input requirements of your e-moto charger. STEP 2: Add the wattage of anything else you want to operate at the same time. STEP 3: Add approximately 20–30% additional capacity for comfortable operating headroom. STEP 4: Compare your result against the generator's continuous/running wattage, not just its advertised peak or starting wattage. Example E-Moto Charger: 1,000W Camping/Track Equipment: 300W Total Load: 1,000W + 300W = 1,300W Add approximately 25% headroom: 1,300W × 1.25 = 1,625W For this setup, we would start looking at generators capable of approximately 1,600W or more of continuous output. Going larger gives you additional capacity for accessories and future equipment. Generator Specs Worth Comparing When shopping for a generator or power station for your e-moto, pay attention to: Continuous / Running Watts The amount of power the generator can continuously provide. Peak / Starting Watts Short-duration maximum output. Don't use this number as your primary sizing number for charging. 120V / 240V Output Determines what types of equipment and chargers can be connected. Inverter Generator Generally preferred when powering chargers, electronics, and other sensitive equipment. Fuel Type Gasoline, propane, dual-fuel, or other options can affect convenience, runtime, and emergency preparedness. Runtime Important for charging large e-moto batteries, especially if a complete charge takes several hours. Outlet Types Make sure the generator has the appropriate outlets for your equipment. Noise Level Especially important for camping, events, pits, neighborhoods, and overnight use. Portable Power Station Capacity (Wh/kWh) For battery power stations, this determines approximately how much stored energy you have available. Not Sure What Size You Need? Send the REV Rides team: 1. Your bike make and model 2. A photo or specifications of your charger 3. How many bikes you want to charge 4. Anything else you want to power at the same time We can help you determine approximately how much generator or power station capacity you should be looking for. The Simple Version Your bike's motor size does NOT determine your generator size. Start with the wattage required by your charger, add anything else you want to operate simultaneously, and then give yourself approximately 20–30% additional continuous output for headroom. For many riders, that makes choosing a generator for the track, camping, off-grid riding, or emergency backup much easier.
