■ Best-use Strategy
When charging other devices with the portable power supply, take note of the LCD Battery Display.
If you plug in devices that drain a high power (like a refrigerator), the capacity level of the portable
power supply can drop very quickly and you may not get exactly 400wh energy. On the other hand,
if you’re charging devices with little power consumption (like LED lights, or mall laptops), you will
get closer to 400wh. If you’re experiencing shorter runtimes, you may need to check the device’s
power requirements, refer to TROUBLESHOOTING which will be discussed below.
