FAQs About of Portable Energy Storage
01
What are the differences between portable outdoor energy storage power supply and traditional generators? What are the advantages?
This is the most crucial issue. The main differences lie in the working principle and user experience:
02
What capacity (Wh) of portable power station should I buy?
It depends on your needs and frequently used devices. A simple estimation formula: Device Power (W) × Usage Time (h) ≈ Required Battery Capacity (Wh).
Below 500Wh: Suitable for charging digital devices such as mobile phones, laptops, drones, and small table lamps, or for lighting during short camping trips.
500-1000Wh: Ideal for weekend camping. It can power small to medium household appliances like rice cookers, mini fridges, electric fans, and projectors for several hours.
1000-2000Wh: Perfect for long-distance self-driving trips and home emergency preparedness. It can run electric kettles, coffee makers, microwaves (note the peak power), and even air coolers.
Above 2000Wh: Suitable for RV travel, professional outdoor work, and long-term home backup power.
03
What is ''false capacity labeling''? How to verify the authenticity of capacity?
"False capacity labeling" mainly refers to confusing the battery cell capacity (Ah) with the total device energy (Wh).
Check the unit: The only standard is Watt-hours (Wh). If the merchant only labels "Ah", convert it using the formula: Voltage (V) × Ampere-hours (Ah) = Watt-hours (Wh). For example, a power station labeled 20Ah with a voltage of 21.6V has an actual capacity of 21.6V × 20Ah = 432Wh.
Choose trusted brands: Reputable brands usually clearly mark the rated Wh and comply with industry standards.
04
Can it power an air conditioner?
This requires extreme caution! Most portable power stations cannot directly drive household air conditioners.
Reasons:
Insufficient power: Household air conditioners have extremely high peak power during startup (3-5 times the rated power), which far exceeds the load capacity of ordinary portable power stations.
Rapid capacity depletion: Air conditioners are high-power consumers. Even if drivable, a 1000Wh power station may run out of power within 1-2 hours.
Solutions:
Confirm the rated power and startup peak power of your air conditioner.
Select a portable power station with power far higher than the air conditioner’s peak power (usually above 3000W).
Consider inverter air conditioner-specific models or use low-power window/mobile air conditioners.
05
How many charging methods does it support? How long does charging take?
There are three main charging methods, and the charging time depends on the capacity and charging power:
AC wall charging: The fastest method. For example, a 1000Wh power station takes about 10 hours with a 100W charger and 5-6 hours with a 200W charger.
Car charging (cigarette lighter port): Convenient for topping up during travel, but with low power and slow speed.
Solar panel charging: The most eco-friendly off-grid charging method. Charging time depends on light intensity and solar panel power (e.g., a 100W solar panel charges a 1000Wh power station in about 10 hours under ideal conditions).
Many products support simultaneous AC and solar charging, which can significantly shorten the charging time.
06
Why are portable power stations so expensive? Where does the cost mainly go?
Costs mainly come from core components:
Battery cells: High-quality lithium iron phosphate (LFP) or ternary lithium cells account for the largest share of costs, directly determining the product’s capacity, lifespan, and safety.
Inverter: Converts the battery’s DC power to AC power for household appliances. Its quality and power determine the stability of output power and load capacity.
BMS (Battery Management System): A sophisticated system responsible for charge-discharge protection, cell balancing, temperature control, etc., serving as the core guarantee for safety.
R&D and structure: R&D costs for shell design, heat dissipation systems, software development, and various interfaces.
What you pay for is a highly integrated, safe, and reliable "miniature power station".
07
What are the AC, DC, USB-C, and car charging ports used for?
AC output (alternating current port): Used to power most household appliances such as laptops, rice cookers, and electric fans. Pay attention to the output waveform—pure sine wave is more friendly to precision electrical appliances.
DC output (direct current port): Usually used to power car electronics such as car refrigerators and air compressors.
USB-A / USB-C ports: For charging digital products like mobile phones, tablets, and cameras. If the USB-C port supports PD fast charging, it can charge laptops at high speed.
Car charging port (cigarette lighter port): Equivalent to the cigarette lighter socket in a car.
08
Can it be used while charging (pass-through function)?
Most products can, but it’s necessary to distinguish between modes:
Normal mode: Can be used while charging, but the input power is usually less than the output power, resulting in slower charging speed or even continuous power depletion.
UPS mode (pass-through function): An advanced feature. When AC power is normal, the power station directly transmits AC power to devices like a "channel" while charging its own battery. When AC power is interrupted, it switches to battery power within milliseconds to ensure uninterrupted power supply for devices. This function is ideal for backup power for devices requiring continuous power, such as computers and NAS.
09
How to store it when not in use for a long time?
Proper storage can greatly extend the battery life:
Charge to 50%-70%: This is the optimal storage power level for lithium batteries. Storing at full charge or low charge will accelerate aging.
Store in a cool, dry place: Avoid high temperature, humidity, and direct sunlight.
Regular charge-discharge: It is recommended to take it out for a full charge-discharge cycle every 3-6 months to activate the cells and calibrate the BMS.
10
Can I carry a portable power station on an airplane?
Yes, but there are strict capacity restrictions.
