Would this work with a Samsung s21?

Sorry, it's only compatible with iPhone 14/14 Plus/14 Pro/14 Pro Max/13/12 Series.

What's the maximum thickness MagSafe case will this work on?

It will work with a magnetic case less than 5 mm thick.

How long is the cable that comes with it?

It says 1.5m cable and you see it in the pictures.

How strong is the magnet? Will it work even if my phone has a case on?

The magnets in the HaloLock™ mini Wireless Charger have 1,200 g of holding force, which ensure a strong magnetic lock on caseless iPhone 14/13/12 series phones and iPhone 14/13/12 series phones with a MagSafe or HaloLock™ case or a standard case with the ESR HaloLock™ Universal Ring.

Great quality cable that charges fast and has wide compatibility. Would definitely recommend!

Really good quality, works with my older s23 which wasn't even advertised as a compatible model. Steong magnet. Nice and compart, firs rhe phone perfectly, super easy to use and charges well. It charges faster than I expected also! About 2 hours for a full charge with a fast charger.

Charges great

Just bought myself a new iPhone 16 and wanted something more modern to go with it, saw this so decided to give it a try. I love it, great if you want to carry on using your phone whilst charging. It just magnetically attaches to the back of the phone until charged. A good price and a good product, would recommend.

Decent charger - does get warm, had an issue with buzzing sound

This charger has a strong magnet and holds the phone really securely. The main issue I ran in to was with a USB C wall plug (Ugreen PD fast charger) that caused the magsafe charger to make a buzzing sound that would pulse for a second, stop for a fraction of a second and then buzz again. It's not a loud sound, and only happens when it has nothing charging on it, but it's really frustrating once you hear it.I solved the issue by switching to an old apple USB A charger (5v 1a). This obviously slows the charging down a little, but as I charge my phone overnight it is not an issue for me and it no longer makes a buzzing noise.I have noticed that any wireless charging causes my phone to get quite warm, however I do need to run an overnight charge on the lower power wall plug I am now using to check if that issue is also resolved simply by using lower wattage.

Good hold and power

Amazing works well with my magsafe case and has strong hold , only things I have to pick at is that the tope of this that stick on the phone may get scratched over time, other then that works well, i haven't done a durability test as I only just got the item

Cute, but didn’t work.

Looks nice, as if it would work quite well, but I used it with and without a MagSafe enabled case and it wasn’t working. Maybe it’s just the product I got, but quite disappointing unfortunately.
