Cigarette Lighter Plug VS Direct connection to the battery, What …

The wires I used to connect the adapter to the battery were connected directly to the battery (2awg too!) so it was getting the maximum power possible. Could it possibly be getting too much power? From what I know the lighter plug will have a greater resistance than the direct cable and will allow for much less power than if connected directly..

How can I make my home internet router work with a battery?

You can connect a battery to the DC side of the NAT router directly and have that be its primary power supply. You would discontinue use of the router''s own power block, and use an appropriate off-the-shelf battery charger for that battery type. This battery charger will be perfectly safe if UL listed, and will simply plug into the wall.

Is it possible to power a cordless drill from wall socket adapter?

$begingroup$ @aaronfarr The easy way would be to start with an AC/DC power supply that has the correct voltage and current. Then, take a battery pack, remove the batteries, and either fit the power supply in it or use the battery pack as a sort of bulky adapter. In that way the drill would remain unmodified and hopefully wouldn''t kill the drill.

Converting LED String Lights from Battery to DC Power Supply

The 5V power supply was too large. When I hooked up a 3V power supply, the LED string functioned properly with the correct amount of light output/brightness.
