Belkin UltraCharge 3-in-1: Does Your iPhone Really Get 25W?

Belkin’s foldable 3-in-1 charger can power an iPhone, Apple Watch, and AirPods together, but the 25W maximum applies only to compatible phones.

The Belkin UltraCharge 3-in-1 Foldable Magnetic Charger can charge an iPhone, Apple Watch, and AirPods at the same time. Its phone pad supports Qi2 charging up to 25W, but that top rate is limited to compatible iPhone models: Belkin lists the iPhone 16 series, while older supported iPhones charge more slowly. The included 45W adapter is the charger’s power supply rating—not the wattage delivered to the phone.

What does the Belkin UltraCharge 3-in-1 charge?

Belkin offers the foldable charger as two designs: WIZ036 (square) and WIZ037 (round). Both combine three distinct charging areas: a Qi2 magnetic phone pad, an integrated Apple Watch charging puck, and a 5W Qi pad for AirPods. Belkin says they can charge all three devices simultaneously.

  • iPhone: Qi2 wireless charging on the magnetic pad.
  • Apple Watch: the built-in fast-charging puck.
  • AirPods: the separate 5W Qi pad, provided the AirPods model and charging case support wireless charging.

The charger can fold into a flat pad or open into a stand, with an adjustable viewing angle up to 65 degrees. Belkin says its ChillBoost design uses passive cooling to help reduce heat; that is a manufacturer feature claim, not an independent temperature or battery-life test. Actual charging performance and temperature vary with the device, its use, and the surrounding conditions. (Belkin product support; Belkin product page)

Will your iPhone receive the full 25W?

Not necessarily. The 25W figure is a maximum for compatible devices, not a standard rate for every iPhone that can attach to the charger. Belkin’s compatibility information gives these limits:

#1 Best Overall
Yojaro 4Pack Silicone Suction Phone Case Mount, Silicon Adhesive Smartphones Stand Sticky, Hands-Free Phone Accessories Holder for Selfies and Videos (Black & White & Translucent & Light Pink)
  • 【Strong Adsorption】The inspiration of the silicone phone suction case comes from the adhesive force of the octopus. Each suction cup phone mount is 3.15 inches long and 2.17 inches wide, with 24 independent suction cups providing a stronger and more stable suction force, so you don't have to worry about your phone falling during use.
  • 【Back of Phone Suction Grip】Remove the adhesive film on the phone suction cup and stick it on the phone case. You can then fix the phone on any smooth surface, which is very convenient. (The phone suction cup cannot be removed and reused after being attached to the phone case. It is recommended to attach it to a regular phone case, not a valuable one.)
  • 【Widely Used】Our non-slip silicone phone sticky grip mount attaches to almost any flat phone case and make it compatible with common mobile phones such as iPhone and Android.You can shoot, watch videos or video calls in the kitchen, gym, dance studio, bathroom and other places.
  • 【Capture the Wonderful Picture】Whether you are a TikTok creator or just like to share videos and photos, this phone suction cup can help you hands-free capture wonderful videos and photos for sharing with friends.
  • 【Note】You can fix the phone suction cup on a smooth surface such as a mirror or glass. If necessary, wipe the suction cup with a damp cloth to obtain stronger suction. Before releasing your hand, make sure the phone is firmly fixed. (Not applicable to rough walls, wooden surfaces, and other uneven surfaces)
Device Maximum wireless charging rate stated by Belkin
iPhone 16 series Up to 25W
iPhone 12–15 series Up to 15W
iPhone 12 mini Up to 12W
Other Qi2-certified devices Up to 15W

These are manufacturer-stated maximums. Belkin’s product page reports an internal test in which an iPhone 16 running iOS 26 or later charged from 0% to 50% in 29 minutes; results vary with conditions, so treat that as a specific company test rather than a guaranteed charging time. Check Belkin’s compatibility details for your model and software version before relying on a particular rate. (Belkin support; Belkin product page)

Does it charge an Apple Watch and AirPods at the same time?

Yes. The three charging positions are designed for simultaneous use. Belkin lists all Apple Watch series, including Ultra, as compatible, and names AirPods Pro (2nd generation and newer) and AirPods (3rd generation and newer) for the 5W Qi pad. Because wireless charging depends on the AirPods charging case, check that your specific case supports Qi charging.

Rank #2
Apple EarPods Headphones with USB-C Plug, Wired Ear Buds with Built-in Remote to Control Music, Phone Calls, and Volume
  • SUPERIOR COMFORT — Unlike traditional circular ear buds, the design of EarPods is defined by the geometry of the ear. Which makes them more comfortable for more people than any other ear bud–style headphones.
  • HIGH-QUALITY AUDIO — The speakers inside EarPods have been engineered to maximize sound output and minimize sound loss, which means you get high-quality audio.
  • BUILT-IN REMOTE — EarPods with USB-C plug also include a built-in remote that lets you adjust the volume, control the playback of music and video, and answer or end calls with a pinch of the cord.
  • COMPATIBILITY — Works with all devices that have a USB-C port.
  • INTEGRATED MICROPHONE — A built-in microphone precisely captures your voice while you’re on the phone, taking a FaceTime call, or summoning Siri — so you’re always heard loud and clear.

Belkin reports that its internal test charged an Apple Watch Series 10 from 0% to 80% in 30 minutes. That result is a manufacturer test, not a promised time for every Watch, and real results vary. (Belkin support; Belkin product page)

What comes in the box, and will a case fit?

The package includes a 1.5-meter USB-C-to-USB-C cable and a 45W USB-C power adapter. The adapter’s 45W rating describes the power supply, not the phone’s charging speed; the phone’s rate depends on compatibility and charging conditions.

Belkin says the charger works with MagSafe-compatible cases up to 3 mm thick. A thicker or non-compatible case may affect magnetic alignment or wireless charging, so remove it if the phone does not connect or charge reliably. (Belkin product support)

What are the price and warranty details?

Belkin’s support page lists a $99.99 MSRP. That is the manufacturer’s suggested price, not confirmation of a current selling price or regional availability. The same official information lists a two-year warranty and a Connected Equipment Warranty of up to $2,500; its terms and geographic coverage should be checked with Belkin for the relevant market. The charger’s enclosure is described as made with 85% post-consumer recycled plastic, excluding the cable and power adapter. (Belkin support; Belkin product page)

Who is this charger best suited to?

The UltraCharge makes sense for someone who wants one foldable charging station for an iPhone, Apple Watch, and compatible AirPods, especially if stand mode and an adjustable viewing angle are useful. The headline 25W benefit is most relevant to compatible iPhone 16-series devices; owners of other listed iPhones should expect the lower model-specific limits above. Before buying, confirm your phone’s charging rate, your AirPods case’s wireless-charging support, case thickness, and the current price in your region.
