Does what its supposed to

Didnt know something like this existed in my search for a dongle DAC/Amp capable of having a power passthrough to charge the phone/ipad stumbled upon this. It is very well built like all ddHifi products and solved my problem of using my Questyle M15i to be permanently connected to the iPad while being charged simultaneously. The description of this product needs to be better stated in bold everywhere as it took me some time to figure out what it does, not sure why it says USB-C to USB-C & Power Adapter it should say - Enable any USB C device to be paired simultaneously, while your iPhone or iPad is being charged. I would give it 5 out of 5 stars.

Thanks a lot for your detailed and genuine feedback, we're glad that you have such positive thoughts about the product and we'll share your thoughts with the brand as well. It'll also help our fellow customers to make the right choice!

Good Utility….!

Very helpful in listening to the Music with the DAC & Amp connected and Source device charging at the same time. Don’t have to worry about the battery power of the source.

Hey there, thank you for the great review and ratings! So delighted that you are loving your purchase. Hope you had a comfortable shopping experience. Cheers!

No more running out of juice when connecting your phone to a dongle DAC. This helps charge your phone WHILE remaining connected to external devices like DACs or even type C earphones
