How much power does the BILT HARD TGA-0258 give you?
On gas, this model is rated for 4,000 running watts and 5,500 starting watts. Running watts are the power available while your appliances are on. Starting watts are a short burst to help things like refrigerators and pumps turn on. You cannot use that bigger number for appliances that need steady power.
On propane, you get 3,600 running watts. That is 400 fewer watts than on gas.
| Fuel | Running watts | Starting watts |
|---|---|---|
| Gasoline | 4,000 W | 5,500 W |
| Propane | 3,600 W | 5,000 W |
Is this model a good fit for you?
This model provides 4,000 running watts on gas or 3,600 on propane. It weighs 61.73 pounds without fuel, so consider stairs and lifting before calling it easy to carry. Its 120V RV outlet does not become 240V with an adapter.
The matching manual confirms carbon monoxide safety shutoff and dimensions, but does not give enough detail for a fair runtime or noise comparison. Ask about the warranty before buying through Amazon: the website policy excludes third-party purchases, while the Amazon listing says ninety days.
The details for this model
Model: TGA-0258. Manufacturer part number: TGA-0258. These are published specifications, not results from our own testing. If a detail is missing, we leave it marked rather than use a number from a similar generator.
A detail to confirm: The matching manual and official TGA-0258 page give 19.09 × 11.22 × 17.91 in.; Amazon gives a different set of dimensions. Warranty depends on seller: the manufacturer website warranty text excludes Amazon purchases, while this Amazon listing says 90 days. No runtime with power use conditions or qualified noise measurement was established in the matching primary documents.

A 120V outlet powers ordinary household plug-in devices. Some pumps and larger equipment need 240V. Inverter models use electronics to control the electricity they supply. THD measures how smooth that electricity is; a lower number generally means smoother power. Check your device instructions before connecting electronics.

How long will it run?
We have not confirmed a runtime figure that says how much power was being used. The listed gas tank holds 1.14 US gal. (4.3 L). The more power you use, the sooner you will need fuel. A runtime measured at 25% load means the generator was only supplying a quarter of its running power, not working flat out.
Propane gives you another fuel option. Follow the manual for the regulator and cylinder size. A small cylinder may not supply enough fuel in cold weather. Read our fuel-storage guide →
What can you run during an outage?
Start by listing the appliances you need most. Check both their running watts and the extra power they need to start. A refrigerator, for example, may need much more power for a moment when its compressor kicks on.
Here is an example, not a test of this generator: a refrigerator using 600 running watts, plus 100 watts of lights and 100 watts for a router and other small devices, adds up to 800 watts. If that refrigerator needs 1,800 watts to start, the total briefly reaches 2,000 watts. Your appliances may use different amounts.
That example is within the listed gasoline running and starting ratings. You still need to check your own refrigerator, each outlet’s limit, and anything else that may turn on at the same time. If you use propane or natural gas, check those ratings separately.
A 1,500-watt heater uses a lot of power on its own. Follow its connection instructions; many portable heaters must plug directly into a suitable wall outlet. This review does not confirm 240V output for this model. Do not choose it for a 240V pump or air conditioner without checking that first. Work out how much power you need →

Starting, moving, and maintenance
The listed starting options are: pull cord. Practice starting it before an outage so you know you can use it when needed. It weighs 61.73 lb. net. Wheels can help on level ground, but they do not make stairs or lifting into a vehicle easy.
The listed warranty is Amazon listing says 90 days; manufacturer website warranty excludes third-party purchases. Confirm seller coverage; do not assume website coverage.. Read the full terms, including whether your seller and intended use are covered. Follow the manual for oil type, oil changes, and storage. Keep track of running hours during a long outage.

Other generators to compare
WEN DF480iX →
The DF480iX gives you gas and propane, electric starting, wheels, and 4,000 running watts on gas. It is a 120V generator, unlike the 240V-capable DF680iX. It may suit appliance cords or an RV, but it cannot run a 240V well pump.
4,000 running watts on gas · Dual fuel · 120V
A-iPower GXS5000 →
The GXS5000 pairs a large 6.3-gallon tank with a claim of up to 20 hours at quarter power. That means about 1,000 watts of use, not the full 4,000 running watts. Higher demand means more frequent refueling.

WEN DF475T →
The DF475T offers gas, propane, electric starting, and 120/240V output. It provides 3,800 running watts on gas. The larger 4,750-watt number is only for the brief extra power appliances need when starting.

Questions about the BILT HARD TGA-0258
How much running power does it provide?
4,000 watts on gasoline; 3,600 watts on propane. Starting watts are only available briefly, not for steady use.
Is it an inverter generator?
Yes, this model is listed as an inverter generator. Check your electronics’ power requirements before connecting them.
Can I use it in a garage if it has CO shutdown?
No. Never run a generator in a garage, even with the door open. Use it outdoors at least 20 feet from homes and openings, with exhaust pointed away. Carbon monoxide shutdown is extra protection; it does not make indoor use safe.
Can I connect it to my house?
Check the voltage and outlets before planning a home connection. Have an electrician choose and install the right transfer equipment and check the generator’s wiring setup. Never connect a generator to a household wall outlet.
Should you consider the BILT HARD TGA-0258?
