September is National Preparedness Month, a useful reminder to check the small systems that help a household stay connected when the power goes out. Ready.gov recommends having alternative ways to charge a phone during an outage. A compact solar charging kit for power outages can support that goal, but only when its limits are understood and the equipment is tested before an emergency.
This guide shows how to organize the iFORWAY 36W portable solar panel and the iFORWAY PB02 power bank around phones and other small USB-powered essentials. It is a preparedness setup for communication and low-power electronics—not a substitute for whole-home backup, medical-device planning, or emergency services.
What a small solar charging kit can—and cannot—do
A portable solar panel creates electricity only when usable sunlight reaches its cells. A power bank stores energy so it can be used later, including after sunset. Together, they can provide a practical daytime collection and nighttime charging workflow for compatible USB devices.
The iFORWAY solar panel is rated at 36W, 13.2V ±5%, and 2.7A ±5%, with conversion efficiency listed at up to 23%. Those are rated specifications, not a promise of constant real-world output. Clouds, shade, panel angle, temperature, dust, cable losses, and the receiving device all affect charging. Treat solar as a way to extend stored energy during suitable daylight, not as guaranteed power on demand.
The PB02 provides 25,000mAh of battery capacity, approximately 92.5Wh, up to 170W total output, two built-in USB-C cables rated up to 100W each, and charging connections for as many as five compatible devices. Its display makes it easier to check the remaining battery level. Those features are useful for prioritizing communication devices, but they do not turn the PB02 into a household power station and do not make it suitable for appliances.
Start with the devices that matter most
Preparedness works better when every device has a clear priority. Make a short list before an outage and record each device's connector and charging requirement. A sensible order is:
- Communication: phones used for emergency alerts, calls, texts, and local updates.
- Lighting: rechargeable flashlights or headlamps that use a compatible USB connection.
- Information: a small USB-rechargeable radio or another verified alert device.
- Navigation and documentation: a GPS unit, camera, or tablet only when it supports an essential task.
- Convenience devices: earbuds, entertainment, and nonessential accessories after critical devices are ready.
Medical or assistive equipment needs a separate, professionally informed outage plan. Do not assume a portable power bank or 36W panel can operate equipment that is safety-critical, AC-powered, high-draw, or required continuously.
How to position the 36W portable solar panel
Unfold all four sections on a stable, dry surface with the active side facing direct sunlight. Even a narrow shadow across one section can reduce useful output. Start with the panel facing the sun as directly as practical, then adjust it as the sun moves. A clear shadow behind the panel is a simple sign that the light is reasonably direct, although only a connected device or meter can confirm actual input.
Keep the panel away from traffic paths, standing water, loose soil, and surfaces that become extremely hot. The product page lists IP67 protection, but connectors and attached electronics still need careful handling. Keep plugs dry, protect the receiving device from weather, and do not leave charging equipment unattended outdoors.
If a phone repeatedly starts and stops charging when clouds pass, disconnect it rather than forcing an unstable direct charge. When compatibility has been verified, it is often more convenient to collect energy in a power bank during steady daylight and charge the phone later from stored power. Recheck the panel angle every hour or two and stop if a connector, cable, or battery becomes unusually hot, damaged, wet, or swollen.
A practical daylight-to-night workflow
Before an outage
Fully charge the PB02 from a normal, compatible wall charger. Inspect its built-in cables, USB ports, and display. Then test every critical device one at a time. Label any separate cable and keep it with the kit. A solar charging kit is far more useful when no one has to search for the correct adapter during an outage.
During usable daylight
Place the panel in direct sun, connect only a verified compatible load, and monitor the first several minutes. Prioritize replenishing stored energy or topping up the most important phone. Avoid connecting several devices merely because ports are available; splitting a limited and variable solar input can make each connection less stable.
After sunset
Fold and store the solar panel dry. Use the PB02's remaining energy deliberately. Enable low-power mode on phones, reduce screen brightness, turn off unnecessary wireless features, and charge in short planned sessions. The PB02's display can help the household decide whether entertainment devices should wait until communication gear is ready.
Build the kit around the equipment, not a wattage claim
The number “36W” describes the panel's rated maximum under specified conditions. It does not mean the panel will deliver 36W throughout the day, nor does it reveal how quickly a particular battery will recharge. Similarly, 25,000mAh describes the PB02 cell capacity, while actual energy delivered to a device is lower because voltage conversion and charging create losses.
For honest planning, avoid calculating an exact number of phone or laptop charges unless you know the receiving device's battery energy, its charging behavior, cable efficiency, and the power bank's usable output under the same conditions. Instead, run a household test: begin with known battery percentages, use the exact planned cables, record the change over a fixed period, and leave a reserve for calls and alerts.
National Preparedness Month charging checklist
- Charge the PB02 and every essential device before severe weather is expected.
- Confirm that the PB02 display, built-in USB-C cables, and ports operate normally.
- Unfold and inspect all four sections of the 36W solar panel.
- Test the panel with each intended cable and compatible receiving device in direct sunlight.
- Write down device priorities, emergency contacts, and local alert sources on paper.
- Store the kit in a cool, dry, accessible location—not in a hot vehicle or damp garage.
- Keep connectors protected from water, grit, and bending.
- Recheck the kit periodically and after every use.
- Follow local emergency guidance and maintain separate plans for refrigeration, medical needs, heat, and evacuation.
Ready.gov specifically advises households to plan alternative ways to charge phones during power outages. Its power outage guidance also covers safety topics beyond charging. Use that official advice alongside local alerts and your household emergency plan.
Frequently asked questions
Can a 36W portable solar panel charge the PB02?
The iFORWAY panel is designed to charge compatible phones, power banks, and small devices, but the exact panel-to-PB02 connection must match the PB02's supported input and charging protocol. Verify the connector, cable, and input requirements, then test the exact setup in direct sunlight before depending on it.
Will the panel produce 36W on a cloudy day?
No fixed output is guaranteed. The 36W figure is a rated maximum, while cloud cover, shade, angle, temperature, and device behavior can reduce real output. Plan with stored energy first and treat solar production as weather-dependent.
Can this solar charging kit run home appliances?
No. This compact setup is intended for compatible phones and other small USB-powered electronics. It is not a whole-home battery system and should not be used for appliances, heating, refrigeration, or critical medical equipment.
Should I charge a phone directly from the solar panel?
Direct charging may work with a compatible device in steady sunlight, but passing clouds can interrupt it. A tested storage-first workflow may be more manageable: collect energy in a compatible power bank during daylight, then charge the phone from stable stored power.
How often should I test an emergency charging kit?
Check it periodically, before forecast severe weather, and after every use. Recharge the PB02, inspect cables and connectors, confirm the display, and repeat a short solar test so that changes or damage are found before an outage.
Prepare the small charging system before you need it
A reliable solar charging kit for power outages is not defined by the biggest number on a product page. It is a modest, tested system with known connectors, realistic expectations, and a clear device-priority plan. Pair the iFORWAY 36W portable solar panel with compatible storage, and use the PB02 25,000mAh 170W power bank to keep essential USB devices organized and ready. Test first, protect the equipment, and keep official safety guidance at the center of the plan.
