    It is very likely that the bulb is burned, because the charging circuit of this lamp is generally simple and does not have a charging protection circuit. The charging voltage output by the circuit will be slightly higher than the voltage of the battery when charging at the right time, because only in this way can the battery be charged normally. In the absence of a protection circuit, this charging voltage will act directly on the bulb circuit, and the bulb will bear a high voltage at this time, and the bulb will be easily burned out if the bulb is turned on.

    The only thing that can prevent this from happening is to not turn on the lights while charging.

It is recommended to use a regular wireless router to implement wireless bridging. 3G mini routers generally have a weak signal and a slower transmission speed. If it is really inconvenient to connect a power strip to the balcony, it is also recommended to buy a TPLink or Mercury mini 3G router (with battery) to achieve it, which is a little more compatible. >>>More

Of course, you can, but you have to make sure that the rechargeable battery inside is a few volts, and then choose to use a few dry batteries, and also consider whether it is easy to install.
