E5 amp
Recently picked up the Fiio E5 for use with my MP3 and CD player. I like
the quality of the sound, but I don't like the fact that the rechargeable battery can't be replaced. When I received the unit, the battery was uncharged and I plugged it into the USB port on the PC for charging where the unit also seemed to function as intended when I plugged in the MP3 & headphones. Question: It would be easy to use a cigarette lighter to USB adapter in the car where I would be using the unit the most often so.... does anyone know whether or not the battery matters when using the unit off USB power? I guess to make it more clear, if the battery were to die or become unchargeable, would it still be possible to power the E5 from the USB? |

There's a lot of stuff like that today. I have an MP3 player and a GPS like that. Unless you drop it into the toilet or step on it, essentially the life of the device is the life of the battery. It would be easy to use a cigarette lighter to USB adapter in the car where I would be using the unit the most often so.... does anyone know whether or not the battery matters when using the unit off USB power? It depends. Some do, some don't. For what it's worth, when I connect my MP3 player to a USB on a computer, port, it goes into it's "removable disk drive" mode as well as charging the internal battery. I can copy files between it and the computer, and play the files that are on it using a media player program on the computer (or when plugged into a car radio that has a USB "player" port). However, I can't access the MP3 player's normal operating controls when it's plugged into a computer's USB port, so I can't play it through headphones. I don't know what it does with a "power only" USB jack since I haven't tried it. I can operate my GPS when it's plugged into a power adapter in the car, but that's sort of a "normal" operating mode for a GPS, though not necessarily for a portable MP3 player or, in your case, headphone amplifier. You have the unit so why not try it? Run the battery down, plug it into a USB port, and see if it works like that. Simple. By the way, you aren't using headphones while you're driving, are you? If you are, you might die before the battery does. -- "Today's production equipment is IT based and cannot be operated without a passing knowledge of computing, although it seems that it can be operated without a passing knowledge of audio." - John Watkinson http://mikeriversaudio.wordpress.com - useful and interesting audio stuff |

It is just permanently plugged into a USB port. |

Everything can be replaced. Open the case, desolder the leads, order a replacement battery from digi-key and solder it back. Have we all forgotten how to repair things today?

You could make a guess if you had some idea what the power consumption on it was; if it's higher than the 500 mA at 5V allowed by USB, you can guess that it won't run directly off of USB. Honestly, this stuff is cheap consumer junk, but just because it's cheap consumer junk doesn't mean it's not repairable. The days of having a TV repair shop on every block are gone but there are still plenty of people out there who will repair electronics for a reasonable fee. --scott -- "C'est un Nagra.

I'm still whittling away at that HD-414 driver and haven't broken it loose from the housing yet.

All too often, the "reasonable fee" is greater than the cost of replacement. That's why we have so much electronic junk in our landfills. -- "Today's production equipment is IT based and cannot be operated without a passing knowledge of computing, although it seems that it can be operated without a passing knowledge of audio." - John Watkinson http://mikeriversaudio.wordpress.com - useful and interesting audio stuff |

There are now products like the Sansa Clip that are so small and tightly packaged and have such a low replacement cost that they are unlikely to ever be repaired by a professional. I did replace the lithium cell in my Microtrack, but the Microtrack cost about 10 times more and is easily 10 or more times larger. The E5 has a replacement value of about $15 and the Clip+ is about $30. The earlier Sansa players were held together with screws, but the Clip+ case seems to be fused together. I think that the E5 may be held together by some plastic pins that it may be possible to push out of the way. Both devices can be operated from a readibly availble separate power source once their batteries lose effectiveness. |

We are at the point now where the major component (weight and size wise) in these devices is the battery. Pretty soon, they will be built into one of the terminals by the battery factory, and when the battery dies, we will just throw them away. |

E5 amp
Just wanted to add that I really like the amp! It arrived a few days ago
and I have been operating it in-line between my MP3 player and cassette adapter. It does well enough with bass and highs that I won't need to bother trying to wire it directly. I know the cassette adapter has some loss, but the E5 helps make up for a lot of it. Very impressive for the price and I am using a cigarette lighter with USB for power. Works great.
