How cold does this 15W semiconductor phone cooler get?

The 15W TEC plate cools below 0 °C within about a minute of switching on, which is why frost visibly forms on the cooling surface in humid conditions — you can see real ice in our product photos. The hidden LED display shows the live plate temperature while it runs. Actual phone back-cover temperature drop depends on ambient temperature, phone model and power source, and the unit requires a 5V/3A USB charger for peak performance.

Does it mount magnetically or with a clip?

Both — it is a 2-in-1 design. The cooler snaps magnetically onto MagSafe-compatible iPhones and onto any phone fitted with the included magnetic alignment ring, and the box also contains an adjustable spring clip for phones without magnets. Retailers can therefore stock one SKU for every customer instead of separate magnetic and clip versions.

What is included in the box?

Each retail package contains the RGB phone cooler, an adjustable spring clip, a USB charging cable and a magnetic alignment ring. The clip and ring are the two mounting options, so end users choose the one that suits their phone.

Why This Model Sells

This is the phone cooler that answers all three questions a retail customer asks at once: does it actually get cold (a 15W semiconductor plate that frosts over — you can film it), how do I know it's working (a hidden LED display that shows the live temperature), and will it fit my phone (magnetic snap-on plus a spring clip in the same box). Because the display hides under the surface and only activates when powered, the unit also looks clean in off-state retail displays — a detail that matters for shelf appeal.

For wholesale buyers it ships from ready stock in Shenzhen in 48 hours, with tiered pricing from 50 pcs and OEM branding from 100 pcs. If you need a custom variant — different LED behavior, housing color, packaging or power spec — our R&D team develops ODM versions on the same platform. See how we produce and test every batch before it ships.

Feature Tour

Every claim below is visible in our own product photos — no stock-image promises.

Hidden display phone cooler: the LED screen only activates when powered

Hidden LED Temperature Display

The temperature readout sits under the surface finish and only activates when the unit is powered, so the cooler looks like a clean disc when off and comes alive with a live temperature number when running. Buyers can literally watch it work — the strongest possible proof in unboxing and review videos, and a genuine point of difference against coolers with no readout.

Large-Area Iced Cooling

An enlarged, widened cooling surface increases contact area with the phone back, moving heat out faster and holding low temperatures for extended sessions. In humid conditions the plate drops below freezing and frost forms across the surface — real ice, not a marketing render, as our own test photos above show.

RGB phone cooler feature collage: approx 55 g lightweight, real frost, ultra slim, up and down airflow, magnetic snap-on dual mode

Approx. 55 g — and Dual-Mode Mounting

Weight matters more than buyers expect: at roughly 55 g this unit stays balanced in one-handed play instead of dragging the phone down. The magnetic / snap-on dual-mode design means iPhone 12 and newer users snap it straight on, while the included adjustable spring clip covers Samsung, Xiaomi and every other 4.7″–7″ phone — one SKU for your whole customer base.

Top & Bottom Airflow — No Blowing on Hands

The dual-vent exhaust pushes air out of the top and bottom edges instead of over the grip area, so long gaming sessions stay comfortable and airflow never hits the player's fingers. It is a small engineering choice that shows up directly in product reviews, and the frost-covered phone in the photo shows the unit running at full load.

Phone cooler on a frosted phone: swift chill and whisper quiet operation

Swift Chill, Whisper Quiet

The cooling chip reaches frost-forming temperatures quickly while the fan runs at low noise — the combination game streamers and mobile-film crews ask for. Adaptive cooling adjusts power to keep the surface dry when humidity is low, and the RGB ring runs through gaming light effects that photograph extremely well in listings and short videos.

Phone cooler retail box contents: adjustable spring clip, charging cable and magnetic ring

Complete Retail Package

Every unit ships with the cooler, an adjustable spring clip, a USB charging cable and a magnetic alignment ring — the two mounting options plus power in one box. That means your listings can advertise a complete kit out of the packaging, with no accessories for end users to buy separately. A 5V/3A USB charger is recommended for peak performance.

Layered Cooling Structure

The exploded view shows how the unit is built: a semiconductor cooling chip, an aluminum alloy heat-dissipation stack and a dedicated fan working in layers, each stage shedding the heat of the one before it. This is what separates a 15W TEC cooler from fan-only imitation products — and it is the difference your customers feel within the first minute of a game.

Made to Be Shown Off

The RGB fan, live temperature readout and frost effect make this the most filmable product in the phone-cooling category. For resellers that means ready-made content for listings, livestreams and short-video platforms in every market — and it is why this model converts better than plain black clip-on coolers at the same price point.

What Wholesale Buyers Ask

What is an RGB phone cooler with a temperature display?

A semiconductor (Peltier) cooler that combines active cooling, a live LED temperature readout and RGB lighting. The display on this model is hidden under the surface and only lights up when powered. It mounts magnetically or with the included spring clip, so one SKU fits magnetic and non-magnetic phones.

How cold does it get?

The 15W TEC plate drops below 0 °C within about a minute, so frost forms visibly on the surface in humid air — you can see the ice in our own photos. The display shows the live plate temperature while it runs. Use a 5V/3A USB charger for peak performance.

Magnetic or clip — which mounting?

Both are in the box. It snaps onto MagSafe-compatible iPhones and onto phones fitted with the included magnetic ring, and the adjustable spring clip covers everyone else from 4.7″ to 7″.

What's included in the package?

The cooler, an adjustable spring clip, a USB charging cable and a magnetic alignment ring — a complete retail kit with nothing extra for end users to buy.

What is the MOQ and can we mix colors?

MOQ is 50 pcs, and white and Obsidian Black mix freely in one order. Tiers run 50–499 / 500–2,999 / 3,000+ pcs; OEM logo and packaging start from 100 pcs.
