What Specific Questions Do You Have?
How Can We Help?
1. What's the difference between rated power and peak power?
Rated power is the maximum power the power station can stably output for a long time, while peak power is the maximum power it can output for a short time (usually 1-3 seconds) to start inductive loads (like motors). You cannot run a 3000W appliance with a 3000W peak power station, because the rated power of such a station is usually 1500-2000W, which is lower than the appliance's power.
2. How is the battery cycle life calculated? Will the capacity drop significantly after 500 cycles?
Battery cycle life is defined as the number of cycles until the battery capacity drops to 80% of its original capacity (based on 80% depth of discharge, meaning each cycle uses 80% of the battery power and then charges to full). Our LiFePO4 batteries have a cycle life of over 3500 cycles. After 500 cycles, the capacity will only drop to about 90-92% of the original, which is not a significant drop and will not affect normal use. Even after 1000 cycles, the capacity remains above 85%.
3. Do your power stations support USB-C fast charging? What's the maximum output for USB-C ports?
Yes, our power stations support USB‑C fast charging.
The USB‑C port of the N1000 has a maximum output of 140W, which can quickly charge laptops, tablets, and high‑power smartphones.
The USB-C3 port of the N300 has a maximum output of 65W, which can quickly charge tablets, and smartphones.
4. What safety features do your products have to prevent overheating, overcharging, or short circuits?
Our power stations are equipped with the BMS (Battery Management System) to ensure comprehensive safety. The key safety features include: overcharge protection (automatically stops charging when the battery is full), over-discharge protection (shuts down to avoid damage when power is low), short circuit protection (cuts off power immediately if a short circuit occurs), overheating protection (reduces power or stops working when temperature is too high), and overcurrent protection (prevents excessive current from damaging components). Additionally, the LiFePO4 battery itself has high thermal stability, reducing the risk of fire or explosion.
5. What fast-charging technology do your power stations use? How long does it take to fully charge from a wall outlet?
Our power stations feature AC fast-charging technology with a built-in high-power charger.
For the N1000 unit (1024Wh), the fast‑charging function supports up to 1440W AC input. It takes approximately 68 minutes to fully charge. Compared with traditional 500W charging (which takes about 4 hours), it saves half the time.
Note that fast charging is only available when using the compatible wall charger included in the package.
Our power stations feature AC fast-charging technology with a built-in high-power charger.
For the N300 (256Wh), the fast‑charging function supports up to 550W AC input. It takes approximately 1.4 hours to fully charge.
Note that fast charging is only available when using the compatible wall charger included in the package.
6. Which solar panels are compatible with your power station? What's the maximum solar input wattage it supports?
The N1000 power station is compatible with our S200 solar panels (200W). It also supports series connection of two 200W solar panels (total 400W). The maximum solar input wattage of this model is 800W. Using compatible solar panels ensures optimal charging efficiency and avoids damage to the power station.
7. How long does it take to fully charge the power station via solar charging?
N1000
Solar Charging: Approximately 5–7 hours under strong direct sunlight (with a 200W original solar panel). Charging efficiency will be reduced on cloudy or overcast days.
N300
Solar Charging: Approximately 2–4 hours under strong direct sunlight (with a 100W original solar panel). Charging efficiency will be reduced on cloudy or overcast days.
8. How do watt-hours (Wh) relate to runtime? For example, how long can a 1024Wh power station run a 100W portable fridge?
Watt-hours (Wh) is the total energy storage capacity of the power station, and runtime is roughly calculated by dividing Wh by the appliance's power (W), minus 10-15% energy loss (due to conversion efficiency and standby power). For a 1024Wh power station running a 100W portable fridge, the theoretical runtime is 1024Wh ÷ 100W = 10 hours, and the actual runtime is about 8.5-9 hours.
9. Can I use third-party solar panels with your power station? Are there any compatibility risks?
You can use third-party solar panels, but there are compatibility requirements.
The N1000 power station: The solar panel's output voltage must be 11V–60V, and the output wattage must not exceed 800W.
the N300 power station: The solar panel's output voltage must be 15V–36V, and the output wattage must not exceed 140W.
The connector type should also match. The input port of the power station is a single XT60/DC7909 port.
The main risk is mismatched voltage or wattage, which may damage the power station's charging port or BMS. We recommend testing compatibility first or using our original solar panels for safety.
10. How to adjust the light-tracking angle of the solar panel to improve charging efficiency?
Angle adjustment method:
1. Place the solar panel on the reflector and adjust the bracket so that the solar panel is at a 90° angle to the sunlight.
2. A sundial is integrated on the solar panel. Adjust the panel angle until the sundial shadow points to the center; this will achieve maximum charging efficiency.

1. What are the common reasons for sudden interruption during charging? How to troubleshoot the issue?
Sudden charging interruptions are mostly related to the power supply environment, device connections, and the triggering of protection mechanisms. Combined with the characteristics of the U.S. 110V AC power supply and the device’s BMS management system, the common causes, troubleshooting steps, and solutions are as follows:
1. Abnormal power supply environment (most common):
① Cause: Large voltage fluctuations (exceeding 110V±10%) in some U.S. regions, loose socket contacts, or unstable power during car/solar charging (e.g., vehicle idling or stalling, temporary obstruction of solar panels).
② Troubleshooting: Switch to another wall outlet and avoid using loose power strips; when charging in a vehicle, check that the engine remains running; for solar charging, check if the panel is obstructed or if the connection cable is pulled loose.
2. Triggering of the device protection mechanism:
①Cause: Over-temperature protection (device surface temperature exceeds 60℃), overcharge protection (not disconnected promptly after full charge).
② Troubleshooting: Check if the device is abnormally hot to the touch, and whether the LCD screen shows the error display. If the battery is nearly full (above 95%), overcharge protection may have been triggered in advance. If overheated, move the device to a ventilated, cool area and leave it for 5–10 minutes. Resume charging only when the temperature drops below 45℃; avoid direct sunlight and do not cover the device. Interruption caused by a full battery is normal protection behavior — simply disconnect and reconnect the power supply.
3. Connection failure:
① Cause: Damaged or oxidized charging cable interfaces, loose solar/vehicle connection cables leading to poor contact; incompatible non-original charging cables causing protocol recognition failure.
② Troubleshooting: Check both ends of the charging cable for wear, blackening, or moisture; check for a loose feel when plugging or unplugging. For non-original cables, confirm whether they support the device’s fast-charging protocol.
2. What causes the powerstation to stop outputting power unexpectedly during discharge? How to troubleshoot this issue?
We recommend troubleshooting by following these steps:
1. Check the battery level: The device may shut down automatically due to a depleted battery. Please fully charge the device before using it again.
2. Check if BMS protection has been triggered: Our power stations are equipped with a Battery Management System (BMS), which includes overcharge protection (automatically stops charging when the battery is full), over-discharge protection (shuts down to avoid damage when power is low), short circuit protection (cuts off power immediately if a short circuit occurs), overheating protection (reduces power or stops working when temperature is too high), and overcurrent protection (prevents excessive current from damaging components). Please reduce the load power, keep the device away from high-temperature environments, eliminate any short circuits, and then restart the device.
3. Check interface connections: Loose plugs may cause power interruptions. Reconnect the interfaces to ensure a secure connection.
3. What should I do to troubleshoot if the solar panel fails to charge the power station?
Please troubleshoot by following these steps:
1. Check that the connections between the solar panel and the power station are securely plugged in.
2. Ensure the solar panel is installed in an unobstructed area with direct sunlight. Charging efficiency will be extremely low on cloudy days or in the evening, and normal charging may not be possible.
3. Check if the solar cable is damaged.
4. Verify that the solar input interface on the power station is functioning properly, then restart the device and test again.
If the device still fails to charge after troubleshooting, please contact us for further assistance.
4. What should I do if the charging speed of the solar panel is abnormally slow, or if the glass is broken or the wiring port is loose?
1. Slow charging speed: Check for any obstructions and ensure the panel angle is correct. Charging speed will naturally slow down on cloudy days or in winter; this is normal.
2. Broken glass / loose wiring port:
If the glass is broken, stop using the product immediately to prevent water ingress and damage to internal components.
If the wiring port is loose, disconnect power first, then reconnect it firmly. Do not disassemble the device yourself if the port is damaged.
In the above situations, if any parts are damaged, please contact our after-sales service for further assistance.
5. Will scratches on the solar panel glass affect power generation efficiency?
Scratches on the solar panel glass will directly affect power generation efficiency and reduce light transmittance. When cleaning the solar panel, it is recommended to gently wipe in a single direction during cleaning; do not rub back and forth forcefully.
6. Do I need a charge controller when connecting multiple solar panels in series or parallel?
No, you don’t need an additional charge controller. Our power stations have a built-in MPPT charge controller that automatically adjusts voltage and current when multiple solar panels are connected in series or parallel. However, please note: when connecting the N1000 power station, the total voltage of series-connected solar panels shall not exceed the maximum PV input voltage of 60V; the total power of parallel-connected solar panels shall not exceed the maximum PV input power of 800W. This ensures safe and efficient charging.
7. What should I do if the screen of the power station displays an error code?
Please first check the Error Display & Solutions in the manual. Different error codes correspond to different faults. Specific troubleshooting steps are provided in the manual.
If you cannot find the corresponding error code, or if the error persists after following the instructions, please take a photo of the error screen, provide the SN code, and contact our after-sales service. We will further troubleshoot and resolve the issue for you.
8. Is it normal for the power station to get hot during charging or discharging? What temperature range is considered safe?
It’s normal for the power station to feel warm during charging or discharging—this is due to energy conversion. The safe operating temperature range is 32°F to 113°F (0°C to 45°C). If the temperature exceeds 113°F, the built-in BMS (Battery Management System) will automatically reduce power output or stop working to protect the battery. To ensure safety, avoid using the power station in direct sunlight for a long time or in closed spaces without ventilation. If the device becomes abnormally hot (case temperature over 113°F), emits an odor, or smokes, disconnect the power immediately, stop using it.
9. Why won't the power station turn on? How to troubleshoot and fix it?
Please troubleshoot as follows:
1. Check the battery level: It may fail to power on due to a low battery. Charge it with the AC charger for 30 minutes before trying again.
2. Check for charging issues: If it still does not turn on after charging, try using a different charging cable or outlet to rule out accessory problems.
