1: Which devices can the STW-800/1000/2500 power ?
Please pay full attention that the AC output port can only charge/power devices that work below the rated power, and do not use high-voltage transformers to power devices.
2: How to know the working time of my power station equipment?
Working time = rated capacity (Wh) * 0.85 / working power of the power station equipment.
3: How long does it take for this outdoor power supply to get fully charged?
From an AC wall outlet, the STW-800 needs 4 hours, the STW-1000 needs 6 hours, the STW-1500 needs 8 hours, and the STW-2500 needs 12 hours.
4: Does the STW series energy storage power station include a built-in PWM or MPPT controller?
All of our STW power stations have a built-in MPPT controller.
5: What is the maximum solar input?
The maximum solar input of the STW-600 power station is 120W, and The maximum solar input of the STW-800/1000/1500 are 200W.
6: What is the output power of the usb-c port?
The output power of the usb-c port is STW-600/1000/1500, and the output is PD 100W.
7: What type of battery is built in?
We use lithium iron phosphate battery (LifePO4), which is more stable, safer, and has a very constant discharge voltage, which allows the battery to provide more power.
