Marine USB charging strip

I'm looking for a strip of say 10 USB outlets to be used for charging phones etc.. Does anybody know of a supplier of such a strip ? 12 or ideally 24V DC.

Re: Marine USB charging strip

amazon et al have multi usb chargers, most using a 120v wall wart. Look carefully at specs or inquire from the manufacturer, as many of these transformers put out 12v dc to the device itself.

Re: Marine USB charging strip

Ive got one aboard thats 12V in and has 6 USB outputs. The outputs are a mix of 1A and 2.5A (for tablets and such) outputs. Dont recall the brand, but got it off Amazon. Very handy.

Re: Marine USB charging strip

I have found a solution using an industrial modular desk top panel and filled it with 8 modules each containing 2 usb charger outlets. Giving 16 outlets. This will be mounted behind an existing charging space on the boat where the pax charge their camera gear etc..

Blue Sea do a 2 outlet marine grade unit but that would have been a PITA to use as I'd have had to mount several of them in a box etc..

This solution had to be client proof (read idiot proof) so has be strong as well as functional !

I'm not very good with electricity. I know I bites but that's all I really know.

But, if you try to use 10, or for that matter, any more than 2, wouldn't each sub port struggle to charge anything?

No in theory you can have as many as you like provided your power supply can provide the current and your wiring is scaled to carry it.

You do not cascade the units, there are no "sub units", they are wired in parallel and all have identical capability.

Wikipedia's explanation of series and parallel

I presume then that for 240v ones, there entirely different?

I asked because our school purchased some 8 bank usb chargers. The very first one is 2.4amp, but the rest 1.5. But even then, if you use all eight, no iPad is fully charged the next morning

Re: Marine USB charging strip

You were robbed.
Source voltage has nothing to do with the overall design. Littlechay is right. A good design will give you exactly what you want. If you can't run all outlets at full power all night, it's because of a poor product design. Return it if possible and get one that works.

I have 2 120v 6 bank from amazon i use onboard and an inverter. If something is not charging overnight its gennerally due to the usb cord. I have had good luck with amazon basics usb cords, but the gas station ones are horrible. Invest in decent adapters as well.
