Hi guys,
In looking to upgrade in the kitchen one of the power sockets to a USB only power socket.
I found and bought this from eBay
https://www.ebay.com.au/p/Jackson-4-Port-USB-Charging-Wall-P…
While it's exactly what I wanted in a bit surprised it's only 3.15A in total which means it will have a hard time charging 2-3 tablets and phones.
Anyone knows an alternative to this socket that can deliver more than 3.15A.
Thanks,
Corneliu
I really think these things should have a power switch - how much power do they consume when you're not charging anything?
Edit: I checked the DETA web site, no technical details. So I emailed the question to them.
One would assume nothing. Lots of places around the globe don't use switches on their wall sockets.
It can't consume nothing.
@[Deactivated]: I also wonder about that possibility - they're not really any different to leaving a normal charger plugged into a power point 24 hours a day.
I know a lot of people leave their chargers plugged in to a mains outlet or a power board, and sometimes chargers get hot and probably sometimes burn out or possibly even burn up.
With these devices, the bits that might burn are hidden in the wall, and I have to wonder whether they're well designed with components that are not stressed, or whether they're built to the lowest price possible.
Having a power switch on them might add a few bucks to the cost, but it's a price I'd be willing to pay, and for the people who don't care, well they can leave it turned on.
I do note that there are a few of these devices (overseas anyway) that have shutters over the USB outlets that turn the power off when the USB cable is removed, which looks like a step in the right direction, but since people are likely to leave that end of the USB cable plugged in all the time anyway, it doesn't really help.
@unclekenz: I'm sorry, @unclekenz, but that makes no sense at all. Are you objecting to what you perceive to be a double negative?
@martijn said that he assumes that it consumes nothing. I said that it can't consume nothing.
Saying "it can't consume anything" has a completely different meaning to what I wrote.
I guess it could be rephrased as "it must consume something", but there's nothing wrong with what I wrote.
USB sockets are not 240v and having something plugged in isn't how a circuit is completed for these step down units.
Best it could do is be on sleep mode but it still has to have a draw so it can detect when a something is connected.
I checked the DETA web site, no technical details. So I emailed the question to them
It must be a tough question - Deta haven't answered yet, despite an autoreply that said they'd get back to me within 24 hours.
Deta got back to me just after 5pm tonight. They say:
Standby power is around 2-4mA, 240X 0.004 = 0.96W max
Almost 1 watt seems very high to me, although it's less than $3 per year.
@pjetson: And you're using the top of the range for the calculation there.
230X0.002 would make it 0.46W, which is less than half.
That looks like want I was looking for. What worries me is that the product has no SKU in the description and I can't really find that anywhere else. I wonder if it's genuine.
I think these built-in USB wall chargers will be useless in 2 years time when devices drain more and more power from USB.
Maybe just get a plain USB wall plate, hide an Anker charger behind the wall and use short cables to link them up.
6.2A
