Works fine, but note that the plug body is fat enough not to fit through the hole in some device cases.

Doesn’t do what is says on the box
Nope … can’t take calls with this lame piece of “tech”. Also doesn’t work below about 12 degrees Celsius, just click, click, click through the car speakers …
Disappointed

Defective, does not charge, by design
Belkin is trying to trick you into buying a defective product. It DOES NOT CHARGE.
It does "slow charge" on my Pixel 7a when plugged directly into power. On my 2024 iPad pro, it says "not charging". When I called Belkin, they claimed neither the new iPad Pro nor the Pixel 7a are on their list of compatible devices for this product. Where is this list of "compatible d...

Disappointed
It does what it was designed to do. However, I have several problems with it. First, when I'm only using the headphone jack, my phone's battery is drained at an alarming rate. I have a brand new Iphone, which I assume many people looking at this product are buying it for. If I leave it playing audio through the 3.5mm jack without plugging it in, with the screen off, it ...

Got this to use in my car since it doesn't have Bluetooth. The charger does not work at all. When I connected the 35mm jack to my car it was all crackly, eventually got sound to come through my car speakers, but charger doesn't work.

Charge time is doubled with adapter
Using this adapter with my "MY PHONE" doubles the charging time compared to just using the same power source and cord without the adapter. This was without even using the headphone port. For the price it should be able to do better than this. I'll really only use this now when I need to keep some power to my phone but also have to keep using my 3.5mm headphones (such as...

Will NOT transfer DATA - and that's a GOOD thing!
Works well, but the best thing about it is that the USB port will NOT xfer DATA, will NOT SYNC, and CANNOT be used for Backing Up the phone. It ONLY charges the battery. It is for POWER ONLY -- not DATA. When I plug it into my computer, the computer does not recognize the phone as a "connected device". (Also verified on the Belkin Website). And that is a GOOD THING - re...

Always breaks
Always breaks after a few months (bought it twice and it failed both times). Also, if you contact customer service to replace it under their warranty, you have to pay to ship the broken one back. Never buying a Belkin product again.

Great 2 in one dongle
Great and affordable replacement so you can plug in a charging cable AND a pair of non Bluetooth headphones @ the same time.
Works great, no drivers needed on the IPad (pro or not,,,)
I suspect that both their usb-c and lightning models work equally well.

Not usable when charging port is plugged in
The adapter works ok with our Pixel 6 as long as the charging port is not used. Plugging in the charging port creates a lot of noise, so it is not usable to play and charge at the same time. After failing with this adapter I bought a Bluetooth to audio adapter and it works much better and was much less expensive.

Works great for what is does
This is great to have when you need to plug into your headphones phone jack and charger. Especially if you have a phone case that mashes using standard headphones plug. The bulkier cases make it impossible to use. Also good for AUX access if you can't use Bluetooth. I feel the use of this will become obsolete at some point with wireless capabilities being more and mor...

Fast Charge
I like that device is small and convenient to carry around in your pocket or purse. I use it on laptop that has a USB-C charging port. It charges my exterior speaker quickly. I wish the thick cable was a little bit longer, but it serves it's purpose.
