Is it safe to charge e17 from wall socket? to speed up charging time or its better to charge from pc usb ?? cheers
LOL
Thanks guys.. I ended up just using dual lock directly on the E 17.

Correct Panda Battery Procedure:
When the device is in use, do not use USB charge. Turn it off. When the E17/E07K is on it's final bar of battery, turn USB charge(or the USB cable) on and charge it to full. And then unplug or turn off USB charge and use until you are on your last bar of battery left. When you see the bars reduce to one, it would be best to start charging(sometimes you are out, and you can't, that's understandable, a few times won't hurt). Li-ion batteries like the one's found the in the FiiO E17 Alpen's don't react well to a full cycle of charge and FULLY de charge until the battery is dead. This has been proven to be actually bad to the life of li-ioin batteries. HOWEVER., you should do a full cycle where you fully charge up the device and use it all the way until the device automatically turns off ONCE every month or two as that has been shown to actually be good for the battery WHETHER you use it constantly or not. Do not fear my friend, even if USB charge is turned off when the device "dies" it will still charge after it runs out of power naturally as the E17/E07K's firmware will reset!
Li-ION batteris on general will last effectively 1000 complete charges before battery drops below about ~70% of the original storage. This is still acceptable by most consumers standards.
20 hours full battery life * 1000 effective uses =20,000 hours / 24 hours a day = 833 days theoretically before the E07K under theoretical conditions will decrease to 70% of its original storage life and this is with a full depletion and then charge cycle. And that is 24 hour usage as well.
FiiO currently reports that they will send replacement parts for a very low price. The battery is not that hard to user replace(but not under warranty).
Partial charges for Li-ION's are better but of course constantly doing partial ones has also been reported to have an effect on the device as well which is why I recommend to charge before all power is gone and to charge till full.
The last point to make is that you can't use a device if you keep on babying it. Using a device and enjoying it is part of that batteries intent and life cycle. Honeslty, ANYTHING you do to it will have an effect on battery life. The majority of the time, it is a minute effect to something like an audio device. (This advice does not hold for Power Wheels, those buggers need proper battery handling). Enjoy the device, theoretically it will hold up well for many years.

Disclaimer: I am not an expert on batteries. I am self taught. Please correct me if something is wrong. But use sources and not just something your papa or person told you to always do.
Keep in mind that the quality of that charger can be important. FiiO usually says to use your legit(not fake) Apple chargers if you have them or a computer but most of those wall chargers shouldn't have any problem.
Some of those wall chargers charge fast. Not a problem but theoretically, a faster charge will lead to a shorter battery life in the long run. But hey, if you baby your device, you will never use it.

Highly recommended (instead of an L7, for example) is this L11 adapter.
I combine it with the cable that arrived with the amp (one straight, one right angle).
It allows one to continue listening or at least not to remove the dock cable when
syncing or charging the iDevice. Fewer make/break cycles is better.
Also the fac that the cable can rotate is useful to avoid strain.
OTOH, it adds one connector to the signal path:

I use an iPad, and what I consider to be a big improvement over most cases:
A strap that makes holding the iPad comfortable at all angles of rotation and of gravity.

I strap my amp to the strap using an elastic band, slide it to the dock connector,
then use the FiiO adapter and cable to connect it. Extremely convenient.
PS: the black bands below on the amp are for use when combined with the iPhone.
I am willing to bet you actually dont have the headphones plugged in all the way. There should be a very tight click when fully inserted.
Each setup is different. Just putting it out there.
But I have not heard any degradation by using the L11 30-pin iDevice with 2 connections compared with the L7 adapter. If anything, it seemed a bit better.
Both are from FiiO and both are good value. I've seen an item like the L11 that was about $25 instead of $10 from FiiO (Amazon prices).
Of course, the L7 gives you both the 30-pin and the 3.5mm cable for $10. The L11 + a cable is nearly twice.
Also, L11 + the patch cable included with the E17 means you don't need to spend extra on cable.
But then how ever was I supposed to convince myself to buy the $300 Monster cable. It's their new Awesome-o series claiming 100Gb/s up and down stream with 300 Audifo fibers per square milimeter in it. It sounds great.
L11 ...
While a great little accessory, one must know that it
1) takes more space (sticks out more) than cabled LODs
2) has a larger cross-section area than cabled LODs so those using cases need even larger openings to fit the L11.
The USB-mini port on the L11 on the other hand is a bit on the looser side, so syncing with computer might not be as successful for long transfers and such.
