I was looking for a power board and found this good deal. Still available in some stores for pickup at least in Penrith, NSW.

I little effort reveals the ports are 1A each

False advertising 5w is not suitable for ipads
It will charge, but take twice as long?
Nope. It won't charge at all if the port is rated @ 1A output.
Yeah, it should still charge. I know my old ipad (iPad 2, not iPad air 2), which comes with a 2amp charger, still charges from my computer usb port which is only running at 0.5amp I believe.
PRetty sure that's meant to be 5v/1A not 5Watts/1A
same.
Power (5W) = volts (5V) x amps (1A)
It should still charge at 1amp just a lot slower. You may need to turn the phone or tablet off while doing it to make it charge a bit faster.
Thanks OP. Decent deal, 1A per port is fine for me. :)
Does anyone know if the pins on the back are on the left, right or in the middle?
Tried Googling for rear, side images nothing found.
Thanks.Thanks. :)
For slightly more, https://www.catchoftheday.com.au/event/power-solutions-for-y… is available with 2.1A/port.
True.
Description is very deceptive as it says it "Features 1 outlet and 2 2.1A USB charging ports" which simply means either port can output 2.1A, but it's not 2.1A per port (meaning total 4.2 output when both ports are used).
1 power outlet, and 2 x 2.1A charging ports.
The above has 2 power outlets and 2 x 1A charging ports. Given the need/propensity for devices these days to require at least 2A for effective charging, then what I linked to should satisfy many people.
Belkin used to offer a similar device, but don't seem to any more.
My existing one does 1A/port for 1 ports and one power outlet, so I'm upgrading so I can remove the need for an additional charger beside the bed.
No doubt the one you linked is better than the laser.
What I was trying to point out is that 2*2.1A =/= 4.2A total unless clearly specified, and the Phillips maxed out at 2.1A when both ports are used.
Or if you don't want to pay for delivery, you can stroll into Kmart and get this (2.1A):

That is 2.1A in total for the Arlec (as opposed to 2 x 2.1A), and like my current one it has an annoying bright LED light, which I painted over with several layers of correction fluid to dull it so it doesn't affect the bedroom at night.
Looks like Penrith is the only store in the Sydney area with stock. Tried various postcodes in CBD, North, South and all gave Penrith as the nearest store with stock.
Not much stock around Brisbane. It's been on sale at this price since Boxing Day.
I'm after something like this but the slow 1 amp charger is a real let down when charging some phones, tablets and Apple devices.
I bought a couple of distribution boards (extension board) named Huntkey 6 Outlet Surge Protected Powerboard with Dual USB Ports. Each USB output provides 5V, 2.1A . Bloody brilliant. I saw them in a number of places such as Kmart, Kogan etc. Good investment.
I haven't tested these devices specifically, but I would suggest always being wary with adapters like this (and indeed cheap USB chargers in general). I purchased an Arlec equivalent mid last year and rather than the output being even a vaguely steady 5V it oscillated between around 4V and 6V at 25Hz.
That is certainly not to say that this device is as bad, but rather than if you have the capacity to measure the output accurately then I encourage you to do so, and consider the value of the device you're plugging in to charge.

Thanks for your input, can I ask how you measured the output current/voltage?
A digital oscilloscope, which unfortunately is not a very commonplace item. Some multimeters may be able to record high and low value for something like that.
(I have this: http://www.rigoloscilloscope.com.au/wholesale/Rigol-Oscillos…)
(I'd just go and buy one and test it, but I expended all my of luxury buying goodwill for a while on a Mini 0805 dashcam)
No information on what amps the USB port supplies, so it could easily be only 500mA which is inadequate for charging phones & tablets.
