This is a thin, cheap Qi pad with a “20W” label and a USB-C cable in the box. It has no magnets, so a MagSafe iPhone charges at 7.5W no matter what the label says, and a Samsung phone at 15W. At around $13 it is priced as a spare pad you leave somewhere and forget.

Version reviewed: 20W Fast Wireless Charger Pad, USB-C, flat non-magnetic Qi pad · ASIN B0C233SVVS · Amazon US listing · no manufacturer model number is printed on the listing.
One-sentence verdict: Fine as a cheap spare Qi pad if you know the “20W” number does not apply to an iPhone and you supply your own wall plug — the mixed rating means the unit you get is a bit of a gamble.
About 6.5 mm thick, non-magnetic; ships with a USB-C cable but no wall adapter.

| Version reviewed | 20W flat wireless charging pad · non-magnetic Qi · USB-C cable included, no plug · ASIN B0C233SVVS · Amazon US |
A thin round pad, about 6.5 mm tall, with a USB-C port on the edge and a small LED. It is unobtrusive and light. Build quality is what the price implies — a plastic shell, a rubberised top surface — and owner reports suggest it is not perfectly consistent unit to unit.
Plug the included USB-C cable into your own wall adapter — a QC 3.0 or 9V brick for the best speed — then lay the phone on the pad. There are no magnets, so you have to find the coil’s sweet spot; if the phone drifts, charging stops. The LED confirms contact, then switches off after about 10 seconds.
The “20W” figure is the ceiling the coil can theoretically supply, not what your phone draws. A MagSafe iPhone is limited to 7.5W on any non-magnetic Qi pad, so that is what this delivers. A Samsung phone can pull up to 15W. Charging through a thin case works; a thick case, a metal plate or a card in a wallet case will interrupt it. The 3.8-star average reflects a pad that works fine for many owners and poorly for a meaningful minority.

There is no durability story: no named manufacturer, no warranty, and a mixed rating. Treat it as a pad you might replace within a year, and do not rely on it as your only charger.
At $12.99 on Amazon (checked August 28, 2026), this is priced as a throwaway pad. For that money you get a slim Qi coil and a cable, which is more than some pads at this price include.
The value question is whether a slow, non-magnetic pad that needs a separate wall plug is worth buying at all when a magnetic Qi2 puck — which actually aligns the phone and charges an iPhone faster — can be found for not much more. As a second pad for a guest room or a drawer, it is fine. As your main charger, spend a little more. Check the current price before you buy.

| Product | Best for | Key advantage | Main drawback | Price |
|---|---|---|---|---|
| 20W Flat Wireless Charger Pad (this pad) | A cheap, slim spare Qi pad | ~$13; thin; cable included; auto-off LED | 7.5W for iPhone; no magnets; no plug; 3.8 stars | $12.99 |
| Anker 313 Wireless Charger Pad | A cheap pad from a brand with a warranty | Anker reliability; 18-month warranty | Also 7.5W for iPhone; no magnets; needs an adapter | ~$19 |
| 25W Qi2 Magnetic Charger 2-Pack | Magnetic alignment for a similar price | Magnets align the phone; two pucks | Speed varies unit to unit; no brand support | ~$17 |
If you want a cheap pad from a brand that stands behind it, the Anker 313 is worth the few extra dollars. If you want magnetic alignment and a faster iPhone charge, a magnetic Qi2 puck costs about the same and is the better buy. This pad only makes sense as a slim, disposable spare. Prices are Amazon figures from August 28, 2026.
This 20W wireless pad is an honest enough cheap accessory as long as you ignore the headline number. It is thin, it comes with a cable, the LED behaves itself, and it will trickle-charge a phone through a thin case. For a spare pad in a spare room, that is all it needs to do.
But the “20W” label sets an expectation it cannot meet on an iPhone, there is no wall plug in the box, no magnets to align the phone, no named manufacturer and no warranty, and the 3.8-star average means the unit you receive is a bit of a lottery. As anything more than a disposable spare, a magnetic Qi2 puck or a brand-name pad is the better spend.

Not for an iPhone. With no magnets, a MagSafe iPhone is limited to 7.5W on this pad. A Samsung phone can reach up to 15W. The “20W” is the coil’s theoretical ceiling, not what your phone draws.
No. It ships with a USB-C cable only. The listing recommends a QC 3.0 or 9V-or-higher wall adapter, which you supply.
Through most rubber, TPU or plastic cases up to about 6 mm thick, yes. A thicker case, a metal plate, or a card in a wallet case will stop it.
It works well for many owners and poorly for a meaningful minority — the usual pattern for a cheap, unbranded charger where units vary.
For a slim spare pad, this is fine. For your main charger, a magnetic Qi2 puck aligns the phone and charges an iPhone faster for a similar price.
