The LA-UA1, with its diminutive footprint and cable of only 6cm length, is extremely easy to carry and use in a variety of environments. It can be used with M/X series players, BTR series Bluetooth amps, Q series DAC/amps.


With its power reconstruction functionality and fully isolated ground and built-in power supply circuits, the LA-UA1 isolates your USB device from the noisy power supply connected at the other end by taking the power and regenerating much purer power to that USB device.


For more details, Please check out the introduction of LA-UA1 at https://fiio.com/productinfo/392240.html

I wish it has a type C head and they designed a neat normal size USB adapter that fit perfectly for it without compromising the fit and finish much.
it'd future proof the thing way more.

Dear user,

Sorry, our customer service does not have related information. But you could try to use and compare by yourself.

Best regards

If one were to use this with the DK-1 type C dock, which has two ports, one for data and one for power, which port would you use this on?
The power port.

I received one from the distributor to try it. It seems, that this device is only good for example in the car! Plugged into a computer I attached an Ibasso DC01 audio adapter, but it was not working! Neither TIDAL nor ROON recognized the DC01 as an output device! If this is true I do not understand why Fiio developed something which cannot be used similar to an Audioquest Jitterbug or an IFI iPower device.

Isn't it the job of customer services to have that information?
What's the point of customer services otherwise?
There is DC-AC-DC circuit inside, so LA-UA1 can reduce the all the ground loop noise(low frequency) when working in car,charging and playing.

Dear user,


The LA-UA1 is a USB Power Purifier which isolates your USB device from the noisy power supply connected at the other end.But it does not support data transmission. When coneccting to computer, only charging is supported.

Best regards

Yes, LA-UA1 designed for car application,it only support 5V voltage input. So FiiO cancel the D+/D- data line, that can avoid the high voltage damage when it connecting with a quick-charge adaptor.
