What's Pass-Through Technology? Glad you Asked!

Folks such as yourself have shown incredible enthusiasm for our new Patriot Power Generator 2500X.
I can’t blame you. It’s the most powerful generator we’ve ever offered. It provides even more power than our very popular 2000X model.
Plus quadruple the expandability. And it charges twice as fast, thanks to our new DualForce Recharging Technology™.
It’s the perfect power source to have on hand in a blackout. With 40% more lifecycles and 25% more peak power. Plus, you get a free solar panel, free shipping and handling in the lower 48 states, and a 365-day, money-back guarantee.
Uninterrupted Power in a Blackout
But we’ve had one recurring question about it. Both from those who purchased the 2500X and from those considering adding it to their preparedness arsenal.
People will say to me, “Frank, Pass-Through Technology sounds pretty cool. But what the heck is it?”
In simple terms, Pass-Through Technology means uninterrupted power. It’s the ultimate “safety net” for your fridge and medical devices. It allows you to protect your appliances when the power goes out. Even if you’re asleep or away from home.
For example, if your fridge is plugged into your Patriot Power Generator 2500X when a blackout occurs, your generator will sense the loss of power and “kick on” power to the fridge. Which, of course, will protect your food supply.
The same is true of your CPAP machine, oxygen machines, and other medical devices. If they’re plugged into your generator, they’ll continue working in a power outage.
Your Questions… Our Answers
Abby, our Lead of the Patriot Power Generator Tech Team, will handle the remainder of questions we’ve received about Pass-Through Technology from customers and those who have heard about the Patriot Power Generator 2500X in a Q & A format.
We want to make sure everyone understands this awesome feature that comes with the Patriot Power Generator 2500X.
Q. What is Pass-Through Technology?
A. Pass-Through Technology is designed for when the grid fails. It allows the Patriot Power Generator 2500X to charge its internal battery while simultaneously powering connected devices. This means that when disaster strikes, critical appliances and medical devices keep running while the generator itself is being recharged from an AC outlet, solar panels, or another power source.

Q. How does Pass-Through Technology work?
A. The Patriot Power Generator 2500X can be plugged into a charging source. While it’s receiving power, it will:
- Direct energy to power any devices you have plugged in (like a fridge, CPAP, or coffee maker).
- Simultaneously recharge its internal battery so it’s ready to provide backup power when seconds count.
If the charging source is interrupted—such as with a blackout, cloudy weather, or unplugging from shore power—the generator automatically switches to battery mode, ensuring seamless power to your connected devices.
Q. How do I use it with the 2500X?
A. It’s incredibly easy to use - no tech expertise required!
At 4Patriots, we believe that power solutions should be simple, intuitive, and accessible to everyone, so using pass-through can be accomplished in two easy steps:
1. Plug your 2500X into a power source, such as your solar panel or a wall outlet.
2. Connect your essential devices.
It's that simple. The generator will do the heavy lifting, leaving you to handle whatever tasks are at hand. 4Patriots designed its 2500X to ensure it could power the important parts of your world so you could focus on other things.
Q. What can I power with it?
A. You can use the 2500X’s Pass-Through Technology to power essential household appliances and critical medical devices, including:
- Food storage: Refrigerators, freezers
- Medical equipment: CPAP machines, oxygen concentrators
- Home security: Battery- or AC-powered security cameras
- Other essentials: Wi-Fi routers and modems, fans, and lights
Q. How will Pass-Through Technology benefit my life?
A. Pass-Through Technology provides peace of mind by ensuring that critical devices remain powered even during unexpected outages. You won’t need to worry about food spoilage, medical device failures, or security system downtime. It’s a hands-free backup power solution that works automatically when you need it most.
Q. Is there a difference in performance when using Pass-Through Technology charging?
A. While using Pass-Through Technology, the generator prioritizes supplying power to connected devices first, and then charges the battery with any remaining available power. If the total power draw from your devices is high, the battery may charge at a slightly slower rate. However, with a 1300W AC charging rate and 525W maximum solar input, the 2500X can efficiently manage both powering devices and recharging itself simultaneously.
Q. Does the Patriot Power Generator 2500X prioritize powering devices or charging the battery first?
A. The generator prioritizes powering connected devices first before allocating excess energy to charge its internal battery. This ensures that any essential appliances or medical equipment remain powered without interruption.
Q. Can I keep the generator plugged into a charging source indefinitely while using Pass-Through Technology charging?
A. The 2500X and Pass-Through Technology power you through any crisis, but smart use keeps it strong. Avoid constant charging to protect battery life, prevent overheating, and maintain peak performance. To maximize battery longevity, it’s best to allow the generator to cycle naturally—discharging during use and recharging when necessary.

- Peak output for the Patriot Power Generator increased from 3,048 W (1800 model) to 4,000 W (2000X model). Continuous output is 1,800 W and 2,000 W, respectively. Storage capacity for DC devices increased from 768 Wh (1800 model) to 1536 Wh (2000 model).
- Refrigerators, freezers and similar appliances maintain a safe temperature by running on cycles. The CDC recommendation is to keep temperature below 40°F and above 32°F. If starting with a cold appliance, running backup power to your fridge for 1 hour will maintain temperature for about 4 hours.
