FlashFish FAQ

Explore portable power stations, portable solar panels and solar generator kits. For all-in-one balcony solar storage, explore the SR5000.

Start with your devices: check their running watts, starting demand and the ports they need. Then compare battery capacity in Wh for the time you want to use them.

E103 offers 179.2Wh and 300W rated AC output; E106B offers 384Wh and 600W; E112B offers 1008Wh and 1200W. A larger battery does not remove output or connection limits. Use the buying guide to compare the options.

Watts (W) describe power at a moment in time. Watt-hours (Wh) describe stored energy. A higher Wh value usually means more available energy, while a higher W rating means the unit can support higher-power devices. Actual runtime depends on device load, operating mode and conversion loss.

No. Check the appliance's rated power and starting surge, then compare it with the FlashFish model's continuous and peak AC output. Do not exceed the product's output rating, and check the user manual before connecting sensitive, medical, heating or motor-driven devices.

E103, E106B and E112B portable power stations use LiFePO4 batteries, as does the SR5000 home storage system. Battery chemistry varies across the wider range; check the exact model and version on its product page.

Divide battery capacity in Wh by the connected load in W for a starting estimate, then allow for conversion losses, standby consumption and changing device demand. This is an estimate, not a tested runtime. The runtime calculator can help you plan.

Pure sine wave describes the shape of the AC output. E103, E106B and E112B list pure sine wave AC output. It does not by itself confirm compatibility: check the device requirements, output limits and exact model manual.

Depending on the model, charging options include a wall outlet, vehicle charging and solar/DC input. Use the charger, cable and input limits specified for your unit. A USB-C output does not automatically mean the same port can charge the power station. Find the matching manual before connecting a panel or adapter.

FlashFish portable power stations are battery products, not fuel generators. Use them according to the manual, keep ventilation openings clear, avoid moisture and heat sources, and do not open, modify or repair the product yourself. For medical or safety-critical equipment, follow the equipment manufacturer's guidance and use a properly rated backup solution.

Store the product in a dry, clean place away from heat, direct moisture and physical damage. Follow the charging, storage temperature and maintenance instructions in the manual for the exact model. If the product has been dropped, exposed to liquid or shows swelling, odor or damage, stop using it and contact support.

If the battery percentage seems inaccurate, follow the instructions for your exact model or ask support for a model-specific procedure. Do not force a deep discharge, overload the unit or open the battery housing to reset the display.

Stop using the unit if there is swelling, an unusual smell, abnormal heat, damage or liquid exposure. Send the model, a photo of the display and the charging conditions to support.

If there is no damage or other warning sign, check that the unit and required output are switched on, cables are seated correctly, the device fits the output limits and the charger fits the input limits. Follow the model manual if a protection warning appears.

If the issue continues, disconnect the load and contact support with the model, order number, a photo or video and what happened. Do not open the housing or repeatedly reconnect a faulty unit.

Match running power, startup demand, port limits and charging requirements to your exact model. A connector that fits does not by itself confirm electrical compatibility.

Keep the unit dry, clean and ventilated, away from rain, moisture and heat. Keep vents clear. Use approved chargers and cables, inspect ports and follow the manual’s storage and periodic-recharging guidance. Do not open, modify or repair the battery housing. Find model-specific instructions before use.

Pass-through or backup behavior depends on the model and the connected load. Check the product manual for the exact model and avoid using loads that exceed the rated output or create unsafe heat, moisture or ventilation conditions.

Check the panel connector, polarity, voltage, current and wattage against the exact power station's solar/DC input limits. A matching plug or panel wattage alone is not enough. Use the model manual, and ask support if any specification is unclear.

Solar panel output changes with sunlight intensity, panel angle, shade, temperature, cable loss and the power station's input limit. Rated wattage is measured under standard test conditions, so real-world charging is often lower.

Use direct sunlight, angle the panel toward the sun and keep the surface free of shade and dirt. Use the correct cable and connector. A solar panel converts sunlight to electricity; it does not store energy by itself.

Only connect multiple panels if the combined voltage, current and wattage remain within the FlashFish product's specified input range and the connector setup is supported. If you are unsure, contact FlashFish support before connecting panels in series or parallel.

A series connection usually increases voltage while current stays closer to a single panel's current. It can be useful when the power station needs a higher input voltage and all panels receive similar sunlight. The risk is that shade or mismatch on one panel can reduce the whole string's output, and the total voltage must never exceed the power station's input limit.

A parallel connection usually increases current while voltage stays closer to a single panel's voltage. It can be useful when panels may receive uneven sunlight or when the power station input voltage limit is low. The risk is that total current can exceed the input rating if the setup is not matched correctly.

Choose a wiring arrangement only after checking the panel specifications and the power station's voltage, current and power limits. Account for the panel's open-circuit voltage and the operating conditions specified by the manufacturer. Do not choose series or parallel wiring from wattage alone.

Find the exact model manual, or send the panel labels and proposed setup to support before connecting.

Keep panels and connectors clean and dry, and follow the cleaning and storage instructions for the exact panel. Do not bend or immerse the panel, spray water directly onto it or use it to charge an automotive battery directly. Check cables and connectors before each use.

SR5000 is an all-in-one balcony solar storage system with a 5120Wh LiFePO4 battery and 2400W rated off-grid AC output. It is a separate category from portable camping power stations. See the SR5000 product page for the system configuration and specifications.

Yes. Ordinary users can complete the standard SR5000 placement and supplied plug-and-cable setup by following the official instructions. Keep the required clearance and ventilation, and follow the grounding instructions.

Grid feed-in, fixed wiring and any local registration requirements must be checked for the installation location. Electrical installation work may require a qualified professional. Ask support before proceeding if the connection method is unclear.

SR5000 has two PV channels, each rated for up to 1000W, for 2000W total. The specified input range is 10–100V DC. Panel voltage, current and connection arrangements must also match the exact manual; do not select panels from wattage alone.

Battery cycle life and warranty cover different things. Cycle-life figures describe battery performance under specified conditions; they are not a promise of the same runtime indefinitely. SR5000 retains its 5-year warranty period. Check the applicable conditions on the warranty page and in your order documents.

Not automatically. Match the intended circuits and devices to the 2400W rated off-grid AC output, connection method and local requirements. A 5120Wh battery does not mean every household load or whole-home installation is supported. Review your plan with support before buying for this purpose.
