If I have a 7.4v battery will this bring down to 5v?

"Specifications: Input range: 8~23v Output voltage:5V " I doubt it will do a good job with lower input voltage than specs promise. Btw, I am not very happy with the phone charging performance when input is 12.5 volts. I have mounted two of these inside the 12V light fixtures above the table in my 19ft camping trailer

This converter is a 12volt input with a 5 volt output , I don't think this is what you are looking for,however they might have other step down converters to choose from,I hope this helps you out.

The charger that came with mine is 4.2 v @ 600 ma. So I guess I'd try the 5 v setting

Hi, this adapter is 7.5V unfortunately, I use it on a phone that works with 6.5V. The voltage drops to 6.8V, it is ok. Do not use this adapter for devices that work with 5.5V

Not sure what you mean... plugged in to a power outlet? Maybe if you have the same output voltage (7.2V) as the battery.

I don't think so. All this does is takes 12vots and than reduces the volts. It does NOT make voltage. You will still need a power source.

No, it will cause the unit to short out, you will need to use a voltage converter

You should have no problems with that battery. I hooked up the light to a 12V supply I have. The light uses 0.8A.

It hasn't in my case. Most electronics logic and components sensitive to a .4 Volt difference run at 1.8V, 3.3V or 5V, as well as the fact that batteries voltage can drop up to a volt or more from full to empty, so there is circuitry to drop a range of voltages down to logic levels and that circuitry should handle the extra .4 volts. That would be the close to limit in my case, though, at which point I'd confirm against Sony branded equipment (the sony adapter is 7.6V as well).

This AC adapter outputs 5.5V and will not work with device that requires 7.5V.

I always used the 4.2v with no problems . I tryed the 3.0 and it was a little dimmer when fully charged ,almost couldnt notice tho

A voltmeter with the plus lead on red and the minus on black or blue will give you the voltage. If you run the battery down it may not charge right away, the charger will trip and not apply a charge. I have found that waiting and retrying will often revive the battery. It will read below 4 volts but will gradually recover.

I have several 4.8 adapters I should have disposed of but didn't. I need a 5v adapter and I believe 4.8 would suffice, but the tips are ever so slightly different in size, of course, so none would connect. +/- 2 v shouldn't make a noticeable difference as far as I know since battery voltages vary as they drain with no ill effect on the equipment..

No, Anything over a 5w panel and you want to run it through a charge controller first. You risk overcharging a battery (which will eventually kill it) if you don't, even 5w is pushing it unless its a 70ah+ size battery and it has a constant small draw from it (Like in a car where electronics are being run even when the car is off)

It might, depending upon battery size and how discharged it is - if it is totally discharged, nothing may bring it back, but if it is just really low, you might try to pre-charge it with a regular charger and then maintan it ( which is what the Tender is for) wihe the Battery Tender. Remember, it is only 1.25 amp and I would think you might need at least 2 amps for charging very weak batteries

I used 5V with no problem. Couldn;t find the specification but everything above 2.5 i think is considered a high

I have the 4000 mAh version which is not pictured on the page I'm looking at right now. But according to the back of it, it's Output is 5V ~ 0.5A.

It might but you would check your user manual to make sure you are getting the correct voltage
