Benks Ice Cooling MagSafe Charger Review: Keeping Your iPhone Cool at 15W

Introduction

Wireless charging is convenient, but anyone who’s used a MagSafe charger knows the frustration: after 10-15 minutes, the phone gets warm, charging slows down, and efficiency drops. The Benks Ice Cooling MagSafe Charger promises to solve this with an active cooling system built into the charging puck itself, allowing sustained 15W charging even in warm environments.

Priced at ¥199–¥249 (~$28–$35) on Tmall, it’s positioned above standard MagSafe pucks (¥99–¥149) but below premium options like the Anker 3-in-1 Cube (¥399). Benks, a well-regarded Chinese accessory brand, has built a strong following for its iPhone-focused accessories.

Design and Build Quality

The Benks Ice Cooler stands out visually from standard MagSafe pucks. The charging surface is a smooth glass-like panel with the Benks logo in the center, surrounded by an aluminum alloy ring. Below the charging surface, a circular vent grille reveals the 30mm cooling fan.

The entire puck is 18mm thick — significantly thicker than Apple’s official MagSafe charger (8mm) or third-party slim pucks. This is the compromise for active cooling. The 1.5m braided cable is a nice touch, matching the premium feel of the aluminum housing.

The fan intake is on the bottom/sides of the puck, and exhaust vents are on the top ring. This design ensures that hot air is expelled away from both the phone and the charging surface. LED indicators on the edge show charging status (solid blue = charging, red = error/overheating).

Cooling Performance

The cooling system uses a thermoelectric cooler (TEC) module — essentially a small Peltier element — sandwiched between the charging coil and an aluminum heat sink. The 30mm fan pulls cool air across the heat sink and exhausts warm air through the side vents.

In testing by Chinese reviewers on SMZDM, the Ice Cooler maintained a phone battery temperature of ~35°C during a 30-minute 15W charging session, compared to ~42°C on a standard MagSafe puck. This 7°C difference translates to noticeably less throttling — the Ice Cooler delivered an average of 12.8W sustained vs. 9.2W for a standard puck.

One limitation: the fan runs continuously during charging. At 22dB, it’s not silent — you’ll hear it in a quiet room — but it’s quieter than a laptop fan at idle. For bedside use, it may be noticeable.

What Chinese Users Say

“Finally, a wireless charger that doesn’t cook my phone! I use it on my desk while gaming and the iPhone stays cool. The fan noise is barely noticeable during the day.” — Huang Wei (黄伟), Tmall Verified Buyer ★★★★★

“Charging speed is noticeably faster than my old MagSafe puck. I measured ~48 minutes for a 0-50% charge vs ~65 minutes before. Worth the premium price.” — Zhou Min (周敏), JD Verified Buyer ★★★★★

“Works great for 15W but the fan does hum. It’s fine in the office but I wouldn’t use it on the nightstand. Also, the puck is quite thick — doesn’t sit flush if you mount it on a stand.” — Lin Feng (林风), JD Verified Buyer ★★★★

“Had it for two months. The cooling still works perfectly. My biggest concern was dust getting into the fan, but after two months there’s no noticeable buildup. The aluminum body feels premium.” — Xu Dan (徐丹), Tmall Verified Buyer ★★★★★

Pros and Cons

Pros

1. Active semiconductor cooling reduces heat significantly
2. Sustains ~12.8W average vs ~9W standard MagSafe
3. Premium aluminum + glass construction
4. Strong N52 magnet alignment
5. 1.5m braided cable included
6. LED status indicator
7. Reduces battery aging risk from heat

Cons

1. Bulky (18mm thick) compared to standard pucks
2. Audible fan noise (~22dB)
3. Requires 20W+ PD adapter (not included)
4. Only works with iPhone 12+ for MagSafe alignment
5. Android limited to 7.5W Qi charging

FAQ

Q1: Is the Benks Ice Cooler compatible with the iPhone 16 series? Yes. It uses the standard MagSafe magnet array compatible with iPhone 12 through iPhone 16 series. It also works with most MagSafe phone cases.

Q2: How much faster is charging with the cooling fan? Approximately 25-30% faster sustained charging. In real-world testing, 0-50% charge takes ~48 minutes with cooling vs ~65 minutes without. Full charge from 0-100% is about 15 minutes faster.

Q3: Does the fan noise bother anyone? At 22dB, it’s comparable to a quiet computer fan. Most users in office environments don’t notice it, but some light sleepers report it’s audible in a completely silent bedroom.

Q4: What power adapter do I need? Benks recommends a 20W or higher USB-C PD adapter. The charger draws about 18-20W max (15W to the phone + ~4W for the fan and TEC). Using a lower-power adapter will result in reduced charging speed.

Q5: Can the fan be turned off? There’s no manual fan-off switch. The fan is controlled automatically by a temperature sensor — it only runs when the TEC module needs cooling. In low-ambient temperatures, the fan may run at reduced speed or intermittently.

Verdict and Rating

The Benks Ice Cooling MagSafe Charger delivers on its core promise: faster, cooler wireless charging. The active cooling system genuinely helps maintain 15W speeds, especially in warmer environments or during extended use. The trade-offs are thickness and fan noise, but for desktop and office use, it’s a worthwhile upgrade over standard MagSafe chargers.
