6Foot2 Posted January 26, 2012 Posted January 26, 2012 Link: PowerPad 16 - Charge and Sync 16 iPads, iPhones and iPads 2
DSapseid Posted January 27, 2012 Posted January 27, 2012 IIRC lapsafe had something similar at BETT this year, cant see it on there site though.
synaesthesia Posted January 27, 2012 Posted January 27, 2012 If price is very low it may well be worthwhile as a secondary charging solution. I suspect however that the sync and charge solutions would be a better all-round use of money (unless these come in at just a couple of hundred quid of course )
mac_shinobi Posted January 27, 2012 Posted January 27, 2012 Could combine 2 or 3 USB mains powered USB Hubs ie (might be better ones ) : Xenta 10 Port USB 2.0 Hub - Mains Powered - Wall.. | Ebuyer.com One multi way to plug each USB hub into One lap safe Assuming 10 USB Cables would be long enough to connect 10 iPads into and said USB Hub would provide enough power without over heating issues etc
synaesthesia Posted January 27, 2012 Posted January 27, 2012 would you honestly trust a bunch of iDevices in those? I wouldn't plug a £3 mouse into a cheap USB hub! 1
mac_shinobi Posted January 27, 2012 Posted January 27, 2012 would you honestly trust a bunch of iDevices in those? I wouldn't plug a £3 mouse into a cheap USB hub! Was just a quick google - as per the comment in the brackets ( there are more then likely better ones out there ). You can see from one of the comments and also the price, not to mention the above comment as per the quote that there are better ones out there lol
dhicks Posted January 27, 2012 Posted January 27, 2012 Assuming 10 USB Cables would be long enough to connect 10 iPads into and said USB Hub would provide enough power without over heating issues etc I actually had a look at those last night on eBay - I'm looking for a decent USB hub to use with the Raspberry Pi. It would seem that those particular hubs provide 2A of power - each USB port can, seemingly, be required to provide 0.5A, and for a charging situation I would have thought each device would draw the maximum amount so you'll be able to attach 4 devices to charge. The other option would be to buy a bunch of individual single-port USB chargers and plug them in to a proper 13A multi-way adaptor, but 3 10-way USB hubs are still probably cheaper than 10 single-port chargers. If anyone knows of a better-powered USB hub, please post a link - the one listed above was the best one I could find yesterday. You used to be able to buy USB hubs with 4A adaptors, but I don't seem to be able to find any reasonably priced ones (although there are some 4-port USB3 ones for around £60).

ChrisJ Posted January 27, 2012 Posted January 27, 2012 We've just got one of these - NoteSync in NoteCase Fun to watch all the devices power up one at a time.
Gigabyte Posted January 27, 2012 Posted January 27, 2012 I looked into this for charging our flip cameras, but unfortunately the power is way too high at 2.1A, whereas USB 2.0 has a max output of 900Ma. Hopefully they will bring out a universal charger for all USB devices.
Arthur Posted January 27, 2012 Posted January 27, 2012 For charging iPad's you could use an extension lead plus several Apple 10W USB adapters or Griffin GC17120 XL USB to Dock cables? USB 2.0 has a max output of 900mA. It is USB 3.0 that's 900mA. USB 2.0 is 500mA.
Gigabyte Posted January 27, 2012 Posted January 27, 2012 It is USB 3.0 that's 900mA. USB 2.0 is 500mA. Note to self - Don't believe everything on Wikipedia.
plexer Posted January 27, 2012 Posted January 27, 2012 That's the whole purpose of the device that was mentioned and whilst the OP was highlighting what seems to be a well thought out solution everyone else seems to be intent on McGyvering something to suit. The device post has been designed specifically for charging and sync of i devices and providing the correct current etc... for fast charge of those devices it is not meant to be used as a general purpose usb charging unit as they state on their website and they also say they are working on one of those.

synaesthesia Posted January 27, 2012 Posted January 27, 2012 I took it as only a charging solution which would appear to be correct unless a) I'm misreading/ignoring something or b) their sites information on that product is wrong. The only thing to say it syncs is the topic which I'm unsure of. Edit: It almost certainly doesn't sync - reviews don't mention it and there's no input USB port.
Arthur Posted January 27, 2012 Posted January 27, 2012 I don't know about other schools, but our bursar would never let us buy a $700 USB charging device from the U.S.A. Surely there must be a company in the U.K. which sells chargers like the one posted by DaveP?
synaesthesia Posted January 27, 2012 Posted January 27, 2012 Just bought in 2 sets of of the Classroom Solution from KRCS for an undisclosed school (not mine) https://www.krcs.co.uk/pages/education/mobile-learning Sturdy stuff and charges & syncs. But lots of cash though, the case on its own from the quotes I remember were just over a grand.
Arthur Posted January 27, 2012 Posted January 27, 2012 the case on its own from the quotes I remember were just over a grand. It's insane how much these things cost. Why are they so expensive?
TLARWise Posted January 27, 2012 Posted January 27, 2012 Loxit do a charge/sync trolley now aswell (16 or 32 unit versions available) Loxit Lapbank iPad Charge/Sync Trolley 16 | iPad Trolley | iPad Cart | Loxit, no idea on pricing though as am not interested enough to check up on it myself.
plexer Posted January 27, 2012 Posted January 27, 2012 Bretford do this: PowerSync Tray for iPad | Apple Product Guide No idea how much it is though. Ben
plexer Posted January 27, 2012 Posted January 27, 2012 Looking at the originally posted product you are correct in that it doesn't appear to do sync as well however they do have products that fill that slot too DS-IP Sync-and-Charge Kit Ben
dhicks Posted January 27, 2012 Posted January 27, 2012 It's insane how much these things cost. Why are they so expensive? Because these devices have to have some thought put into their design, and then someone has to manufacture them. If each iPad is drawing 2A as it charges, you can fit half a dozen of those on a standard 6-way power strip. Any more than that and you'll burn the fuse out, so anything that charges more than 6 devices at a time must be doing something a bit more cunning. If you're making anything in quanaties of less than, say, 10,000 it's not practical to set up a cheap production line in China, so you have to pay people to manufacture stuff for you more manually, which means you need cash for premisis and wages for 3 months before you start. 2
plexer Posted January 27, 2012 Posted January 27, 2012 UK Company: C3-Case iPad, iPod, Amazon Kindle, Nintendo DSI, Sony PSP charge and sync component for USB cart/case manufacturers. Think we've had their products posted about before. Ben
plexer Posted January 27, 2012 Posted January 27, 2012 The products made by Datamation as posted are powered by the Cambrionix tech from Cambridge Depending on what the cost of that board is from Cambrionix it would be simple enough to have an enclosure fabricated. Ben 2
