Danger Will Robinson: Some battery chargers are designed to be stand-alone power supplies. Most are not. If your charger does not specifically say it can be used this way, do not try it. Absent a battery you may have poor regulation and very high noise.

As others have stated, it depends on the power requirements of the component but I wouldn't do it. The trickle charger has to put out more than 12v to charge the batteries so you run the risk of too much voltage and not enough current. As an alternative...Years ago I would charge batteries for RC cars from a 12v auto battery. To keep the auto battery charged I would attach a 10amp battery charger that plugged into the wall. This arrangement is quite similar the way backup power supplies work as well as the way most of our shore power charger/battery/12v circuits work on the boat. Lawn and garden (U1) batteries are cheap ($30) and perfect for a project like this. Or maybe you already have an old 12v sitting around. Even a motorcycle battery would be big enough for just about everything except an inverter, a radar, or a anchor windlass.

Depends on what you are testing; a Navigation instrument might need an amp, or a light will need a little more, or a pump may need 5amps, or a windless may need 20amps. Trickle chargers are usually rated for 2amps. Not sure of consequences if it doesn't work. Best to protect the charger w an inline fuse and the device w an inline fuse of the right size. There are several devices that come with 120AC to 12VDC transformers. My Garmin GPS and a West Marine VHF came w one. I have several from kid's toys, too. You can also plug the device into the 12V socket in your car. Let us know how that goes?

Can I do this? I would like to check a few things and this is easier off the boat. It's a small trickle charger. Can I clamp on the alligator clips and test away?
