The Flashfish 300W solar power station is a compact, lightweight power station that works with solar panels for off-grid recharging. Multiple AC, USB and DC outlets let you charge several devices at once.

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

The supplier lists a capacity range for this model. Contact us if you need the exact figure before you order.

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 who needs to run high-wattage appliances.

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

Built to recharge from the sun: a compact, solar-ready 300W station

If your plan involves staying off-grid for more than a day or two, how you recharge matters as much as how big the battery is. This Flashfish 300W station is designed to work with solar panels and has multiple AC, USB and DC outlets, in a compact, lightweight design.

Right for you if…

You plan to recharge with solar while camping or off-grid
You want a compact, lightweight unit for small devices
You want small-device backup at home

Look at something else if…

You need to run high-wattage appliances
You need a large battery for multiple days

How long it could run your devices

Based on about 195Wh usable from a 230Wh battery, after roughly 15% lost to conversion.

Smartphone chargesabout 13
Laptop (about 60W)about 3.3 hours
LED lamp (about 10W)about 19.5 hours
Small fan (about 40W)about 4.9 hours
CPAP machine (about 40W, check yours)about 4.9 hours

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

Note on capacity: The supplier lists a capacity range of roughly 230 to 296Wh depending on configuration. The runtimes below use the lower 230Wh figure. Contact us if you need the exact number before you order.

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

Good to know about this one

Panels and power stations must match in connector and voltage. Send us the panel model you are considering before you order, and we will confirm it fits.

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.
