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.
