The GridGuard 300W portable power station is a compact, grab-and-go battery pack with 13 output ports, so you can run and charge phones, laptops, fans and other small devices from one unit. It is built for travel, camping and keeping essentials running during an outage.

A portable power station stores energy in a rechargeable battery, so there is no fuel, no exhaust and no engine noise. Recharge it from a wall outlet before a storm or trip, and check the specs below for the other charging inputs this model supports.

Good to know

Capacity is listed two ways by the supplier. Check the product options at checkout, and contact us if you need to confirm which configuration ships.

Watt-hours (Wh) describe how much energy the battery stores; watts (W) describe how much power the unit can deliver at once. To estimate runtime, divide the battery's Wh by the wattage of what you are powering, then allow for conversion losses. Add up the wattage of everything you plan to run at the same time and keep it below the unit's output rating. It is not designed to run a whole house, central air conditioning or other heavy-duty appliances.

Who this is not for

Anyone planning to run large appliances such as space heaters, refrigerators with high start-up loads, or power tools.

Setup and care

Charge it fully before first use and before a storm or trip
Store it in a cool, dry place and top it up every few months
Do not charge or discharge it in freezing or very hot conditions
Use cables and panels rated for this model

Frequently asked questions

How long will it run my devices?
Divide the battery's watt-hours by the watts your device uses, then allow for about 15% loss. The estimates above show typical examples.

Can I use it indoors?
Battery power stations produce no exhaust, so they can be used indoors. Keep them dry, ventilated and away from heat sources.

Can I bring it on a plane?
Usually not. Airlines limit spare lithium batteries to about 100Wh (up to 160Wh with approval), so most power stations cannot fly in carry-on or checked bags.

Does a solar panel come with it?
Only if the specs above say so. Panels are otherwise sold separately, and our team can help you match one to this unit. Call 1-800-680-4080.

WHAT THIS POWER STATION IS FOR

13 ports, one battery: charge everything at once

The real problem on a trip or in an outage is rarely one device. It is a phone, a laptop, a camera, a light and a fan all needing power at the same time. This GridGuard 300W unit has 13 output ports (AC, USB-A, USB-C and DC) and 100W USB-C fast charging, so one compact battery can handle the whole pile.

Right for you if…

You are charging many devices at once, such as phones, a laptop and a camera
You want a grab-and-go kit for road trips, camping or RV travel
You want emergency power for phones, lights and fans

Look at something else if…

You want to run a refrigerator, space heater or power tools
You need a battery big enough for multi-day use without recharging

How long it could run your devices

Based on about 131Wh usable from a 155Wh battery, after roughly 15% lost to conversion.

Smartphone chargesabout 8
Laptop (about 60W)about 2.2 hours
LED lamp (about 10W)about 13.1 hours
Small fan (about 40W)about 3.3 hours
CPAP machine (about 40W, check yours)about 3.3 hours

Output limit: 300W continuous. Everything running at the same time has to stay below that number.

Note on capacity: The supplier lists two capacities: 155Wh for the unit alone and 296Wh with the 60W solar panel option. The runtimes below use the lower 155Wh figure. If your configuration is 296Wh, they are roughly double. Contact us to confirm which ships.

Rough estimates using typical device wattages. Real results vary with the device, temperature, sunlight and battery age.

Good to know about this one

Check what your laptop charges at. USB-C PD at up to 100W can charge most USB-C laptops directly, but a laptop that needs more power will charge slowly or not at all.

Plan before you need it

A power station is only as good as its charge. Before the forecast turns, charge it to full and keep it topped up every few months in storage. Ordering ahead lets you test it with the devices you actually plan to run, while there is still time to ask us questions.
