That might be because they tried to follow the standard. A charger should nowadays short circuit the D+ and D- at the device side. I had to modify a micro USB cable to get my phone to charge from an USB battery.

That's interesting. I assume this is done so the device can sense that it's connected to a charger instead of a computer?

Yes, it seems that way. For the phone it only trickle charge if connected to a computer. When you connect to a real charger it charge faster. The annoying thing was that if you connected the phone to an USB battery it would not charge at all since it detected that it was not a computer and not a charger.

Yeah... That's the problem with proprietary connectics too (I think about my Samsung Omnia...)
Intelligent manufacturers make entirely USB compatible devices, greedy ones no !

Yeah, i got a samsung too. Though it woudn't be that much of a problem, until i realised i needed a second cable for work.
Going to a shop to find an ipod cable is easy enough, but for the samsug , Unn no ! Same for the cases.

I disagree, SonyEricsson or Nokia branded phones doesn't use microUSB for charging or PC connection (that no longer true for Nokia phone on the PC connection, but SE still use their own connectors for both)

The Nokia phones that charge using USB use micro USB. Charging using USB is a new thing with Nokia phones so very few phones have it. The Nokia N85 have it for example.

You disagree that an agreement was made? There is nothing to disagree about, it is a fact. However, this was a recent agreement/decision. They said it should be a reality by 2012. So not all current phones conform to it at this point. I very much doubt current models will be retrofitted.

Has anyone tried using one of the solar rechargers with the cybook? I can't think why it wouldn't work, but it would be nice to hear from someone who's tried it. It would definitely be the best solution for using the cybook hiking or whatever.

HarryT · 07-30-2009, 03:07 AM

I suspect that, unless you're in the Sahara desert or somewhere equivalent, it would be rather slow. One of the several available devices which will recharge from a "AA" battery is almost certainly a better choice.

Jellby · 07-30-2009, 06:58 AM

I have used the Free Loader, and it works fine. It's a bit "tricky" because it's not easy to read the Cybook while charging, and the Free Leader should not be powering a device while charging itself. I think it's a good solution for travelling, even to "civilized" parts (the Free Loader can charge other devices like mobile phones, mp3 players, etc.)

The best solution would surely be one of those chargers with a crank handle like these: HERE and HERE (from a german supplier)

I've never tried one, but I have 2 flashlights that work this way - very nice and good for the environment!

Here's a link to something at Maplins. I might pop along and get one myself at that price!

Naa, I very much doubt that. Unless you buy the very lame cheap-china-production, as usually found on eBay, a solar charger would do just fine. However, I would recommend using a solar charger with attached battery, so you can charge whatever device from that. (I did not look for a certain device to display, but I think you get the point.)

As for the power from the sun, a good sunny day delivers approximately 1.000 watts per meter², so you can do the maths on what panel you need

[EDIT]
Oh, i forgot: You are not used to a sunny day in the UK, are you?

...

Sorry, I just could not drop that one

Hunh! I hadn't seen the crank-type charger....How long does it need to be cranked before it can charge anything? On the other hand, that's what kids are for

I guess you're right about the UK sun--I've only been here 6mo or so and still expect San Diego(on a gut level, I mean) weather. Rain in the summer is still a novelty....

Definitely very little Sun this summer, at least. It's been a very, very wet July.
