Lay the phone down flat and it charges. That’s the whole of the Anker 313, a plain Qi pad with no magnets, no stand and no wall plug in the box.
It’s cheap, and it comes from a brand with a real warranty. But an iPhone only charges at 7.5W on it, which is roughly half what a MagSafe or Qi2 charger gives you.

One-sentence verdict: Buy it if you want the cheapest way to charge a phone on a pad overnight and don’t care about speed or alignment; skip it if you want fast charging, magnets or a charger that works straight out of the box.
A basic flat Qi pad — no magnets, no stand, and no power adapter in the box.

It’s a small, flat, round puck with a rubbery top and a Micro-USB input. Unremarkable, in the way a cheap accessory should be: it sits flat, doesn’t slide around and takes up very little space.
For the money, the build is fine. Mostly. The number of owner reports about units failing within a month does suggest quality control isn’t perfect, though.
Plug it into an adapter you already own, since Anker doesn’t include one, and set the phone on top, roughly in the middle. It starts charging.
There’s no magnetic pull to guide you, which matters more than it sounds. Drop the phone on it in the dark, miss the coil, and you can wake up to a phone that never charged at all.
Speed is the weak point, and there’s no getting around it: at 7.5W to an iPhone, this pad is slow by 2026 standards, when even inexpensive MagSafe and Qi2 pads deliver 15W or more and hold the phone exactly where it needs to be while they do it.
The low heat is a real upside for overnight charging, though. Placement tolerance is average, and without magnets, one knock can slide the phone off the coil.

This is where it gets mixed. Most units work for years, but a meaningful minority stop working after a few weeks, and that shows up again and again in reviews. Anker’s 18-month warranty is the safety net, and Anker’s support team is generally responsive, so a dead unit gets replaced instead of being money down the drain.
At $18.99, it’s inexpensive. Remember, though, that you also need to supply an adapter, which adds to what it really costs to get it working at full speed.
For a slow, no-frills overnight pad from a brand with a warranty, that’s acceptable. But for a little more money, a Qi2 or MagSafe pad charges an iPhone twice as fast and holds it in place with magnets, and for most people that’s the better buy. If you already have an adapter, we’d call this a fair buy under about $15.

| Product | Best for | Key advantage | Main drawback | Price |
|---|---|---|---|---|
| Anker 313 Wireless Charger Pad (this charger) | The cheapest simple overnight Qi pad | Low price, brand warranty, runs cool | 7.5W for iPhone; no adapter; no magnets | $18.99 |
| Anker MagGo 3-in-1 Qi2 15W | One charger for iPhone, Watch and AirPods at full speed | Qi2 15W, adapter included, magnetic hold | Costs much more | $69.99 |
| Apple 20W USB-C Power Adapter | The adapter this pad needs | Reliable 20W USB-C brick | Adapter only, no pad | $14.99 |
If you want real speed and magnetic alignment, step up to a Qi2 or MagSafe pad. If you buy the 313 anyway, pair it with a 20W USB-C adapter to get its rated output.
Competent. Cheap. Slow. It runs cool, it comes from a brand that honours its 18-month warranty, and its enormous review history is mostly positive. For an undemanding overnight charge, it does the job.
It’s showing its age, though. iPhone charging is limited to 7.5W, there are no magnets to line the phone up, and you have to bring your own adapter. For a little more money, a Qi2 or MagSafe pad charges twice as fast and holds the phone in place. Only buy the 313 if the lowest price and a brand name are what matter most to you.

Figures marked “Anker” are the manufacturer’s published claims. “N/A” means the value is not listed on the Amazon listing or Anker’s product page.
At up to 7.5W, roughly half the speed of a MagSafe or Qi2 charger. That’s fine overnight but slow for a quick top-up.
No. You’ll need your own USB power adapter, ideally a Quick Charge 2.0 or 3.0 one, to reach its rated speed.
No, it has no magnets, so your phone just rests on the pad and you have to place it over the coil yourself.
Through most normal cases up to about 5 mm thick, yes. Metal plates, ring holders and card slots block it.
A minority of units fail within a few weeks, and it’s a recurring complaint, but Anker’s 18-month warranty covers a replacement if yours is one of them.
Only if the lowest price and a brand name are your priorities. A Qi2 or MagSafe pad charges twice as fast for a little more money.
