Is there a cordless phone with a main computer and no external AC?
I got it. 1. have a stable high capacity mobile power supply + a voltage adjustable plate can be adjusted (5-12 volts, boost general cordless telephone with 5-6-9 volts more. 12 volts is not much) + power line on the line, you must be satisfied. The outdoors can also be used. But the distance is better than the walkie talkie.
If your cordless phone host is 5V, you can use the mobile power, with the appropriate conversion line or self transformation is also possible, but the mobile power is out of power, you have to charge.If you have DIY technology. Cordless phones can be handled without the need for an external AC. It won't be a problem,.. Here's your advice
Cordless phones on my desk don't use alternating current. Powered by a mobile power supply. Power outages can be used. The premise is that my host needs 5 volt DC power.
