Q: Why the AC function doesn’t work and the AC protection sign is
displayed on the screen while the AC switch is on?
A: To ensure the safety of users, the AC port does not automatically restore the output until the AC
protection status is manually cleared. When the temperature protection or low-power protection is
removed, please restart the AC switch manually or restart the device to restore the AC function.
When the temperature goes out of the range or the battery capacity is too low, the device will
automatically turn on its self-protection; the AC function can only be turned on manually when the
temperature is in the range or the battery is up to a certain level.
Q: I bought a MPPT module, could you tell me how to connect and
configure it?
A: Please follow the instructions in MPPT operation manual to connect the MPPT module with
AR500. The MPPT output voltage shall be set to 14.8V, while output current shall not be higher than
18A. If the set voltage is higher than 20V, it will damage the components.
Q: Why does it take longer to charge when I use the wireless charging
function?
A: Please align the screen-printed wireless charging label on the device with the power source.
Positional shift may reduce the charging efficiency.
Q: Why doesn’t my phone display fast charging symbol when I use two
USB-A ports to charge it simultaneously?
A: Only one of them is used, the fast charging function of the USB-A port starts work. If you want to
use fast charging to charge two external devices at the same time, using one USB-A port and one
USB-C port simultaneously can make it.
Q: Why can’t the device be shut down during charging?
A: This device has a charging activation function. During charging, the device is activated, and the
external charger provides power for the device, so it cannot be shut down.
Q: The rated power of the device hasn’t reached 300W, but why has the
protection function of AR500 already been activated?
A: Some electrical appliances, such as electric drills, fans, etc., have large capacitance or inductive
components in their internal power supply section, called inductive or capacitive loads.
Although the rated power of these two loads is not high, their actual power and peak power are
much higher than their rated power. Especially for inductive load, when it starts working there will
be a peak power, and its starting power is several times or even dozens of times as much as the
rated power. Capacitive and inductive loads mainly include: electric fans, motors, air conditioners,
electric drills, and equipment with built-in power switches.
