Charging Power Hubs

office.

here are charging hubs (by Anker, etc) that have 4 or 6 usb ports that supp ly 2.4 amps each. But these are made for charging phones and tablets and ap parently have intelligent charging profiles for specific phones.

Just a follow on. I want to power multiple rPis via micro usb cables into t he micro usb on the rPis, not through the 4 usb ports.

I doubt if there is much intelligence in such products.

Check that the hub's PSU has sufficient wattage to power the desired number of Pi's simultaneously. There are plenty around that claim to put out 2.4A on each of the ports, but only have a 3A PSU.

I just bought one off eBay for around $12.50. Says it can provide 2 A on four ports and 1 A on 2 more. I'll let you know how well it works when I hook up my new rPi 2 along with my old one.

I have successfully powered 6 RPis from one of these for the last 3 months

I've got one of these:

and one of these: I use both for running Pis, Chromecast, USB hub and for charging Nook, Kindle, various Phones. Standard "figure 8" socket, so power leads readily available. Make sure you use good quality USB A to micro leads to get full power to the Pi.

That's exactly what I needed to know. I have one on order. Thanks

I currently have a single 3.6A PSU supplying a 5 port switch, two Sipura VOIP ATAs and a Pi. I used a daisy-chain of barrel jacks, as gutarists use for their effects pedels, and cut off one of the jacks and spliced on a micro USB for the Pi.
