Defective, does not charge, by design
on May 27, 2025
Posted by: Cos0
from Boston, MA
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 devices"? Certainly not anywhere you're likely to see before you buy this defective, deceptively advertised trinket. Who would ever expect that something like this would only charge a few specific models of phones and tables, and not be "compatible" with most others?
I expect Belkin won't publish this review but it's worth a try, so save other people the frustrating of accidentally buying this item expecting it to work. I'm also posting similar reviews elsewhere.
No, I would not recommend this to a friend.

[This review was collected as part of a promotion.] Works fine, but note that the plug body is fat enough not to fit through the hole in some device cases.
I would recommend this to a friend!

Disappointed
on January 12, 2024
Posted by: nateboards
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 drains battery at the same rate as if I were streaming video with the brightness at max. I just feel like it shouldn't use this much power.
Second, if I plug it in to a charger with a high wattage, say, a USB-C laptop charger or high-wattage fast charger, it doesn't charge the phone, and the audio coming through the headphone jack has noticeable noise.
Third, when using headphones, occasionally there will be some brief static when the adapter gets shifted. Not a dealbreaker, but on top of the other issues, it's annoying and I think it's worth mentioning.
Finally, I just don't like the way it looks and feels. I think that it's too bulky, and it doesn't feel as premium as the price should warrant.
Overall, I don't recommend this product at this price. If it were a quarter the price, I really wouldn't have minded these issues, but at the price I paid I expected to receive a premium product, and I don't feel that I did.
No, I would not recommend this to a friend.

Did not charge, 35 mm connection sometimes works
on January 1, 2024
Posted by: KG82
from Saint Paul , MN (purchased at Office Depot)
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. Tried it in the house connected to my charger and I tested the charging cable I use in the car. My cable was fine this adapter was a waste of money.
Belkin usually makes better quality products, either I got a bad unit or this one is poorly designed.

Charge time is doubled with adapter
on November 24, 2023
Posted by: Philip r
from AZ
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 phone calls). Disappointed
No, I would not recommend this to a friend.

Will NOT transfer DATA - and that's a GOOD thing!
on September 10, 2023
Posted by: Tommy texas
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 - read on.
Why is that a GOOD thing? Well, now I don't have to worry about using a charging port at the airport, cafe, or other place where the "free" charging port may have been HACKED to access the data on my phone while I use the "free charger". One less thing to worry about!!!!
I would recommend this to a friend!

[This review was collected as part of a promotion.] This fixed the popping sound that was happening with the apple adapter. And allows for charging. So bonus!
