Spend a dollar more for onn 32W Dual USB-C and USB-A Port Wall Charger, Fast Charging

Community Reviews

This onn 20W USB C wall charger is a tiny, cheap backup brick that works well for basic USB C charging and even powered an eero router after the original adapter failed. The low price is the main draw, and the smaller kit version adds a 3 foot USB IF certified USB C cable for just a bit more. The USB C port is capped at 20 watts, with USB A limited to 12 watts, so it is not ideal for phones that can pull more power. The single USB C port also feels limiting for a charger meant to stay simple and inexpensive.

This seems to be the lowest price in a while from what I'm seeing.

These are actually pretty good prices! Left one back in the hotel room when you checked out? No biggie... Less. than a price of coffee these days.

Are these "fast charge". Am I being paranoid if I use this as my regular overnight charger, will it mess anything up?

If you want the smaller form factor over the 32W charger, spending an extra $1 also gets you a 3ft USB-IF certified USB-C cable with the 20W charger:

It's device specific. Most iPhones charge at 30W and above. Believe 17 charges at 40W, 17 Pro at 45W. Android phones are at that level and higher. What device is limited to 20W, a cell phone from 10 years ago?

That's the point. Why use a charger that is half your charging limit and will still be considered "fast charging" by your battery? Might as well get max speed and charge. Plus who uses a $4 charging brick to charge a $800-1300 cell phone. Belkin 30W go for $15-20 day and night, Apple's own 45W charger (which is the best on the market outside of Google's recently released charger) was chronically at $30. No point in cheaping out and being forced to wait longer while the phone charges (most people i know charge at night and only top off using fast charge during the day). Others will chime in and say "just wait." Time is money and i dont have time

Upto iPhone 16 (base variant) were still at 23-24W (not the Pros). It was in base 17 they changed

$2 everyday of the week on eBay. Also probably not going to get 20w… 15w is what you'll get

The price is right, but it needs two USB and two C ports! Only one C port is too limiting!
