Apple’s Airpower never made it. But we have quite a few alternatives on the market with Anker now joining the party with its PowerWave+ Pad with Watch Holder (B2570) which can simultaneously charge an Apple Watch and a phone. Let’s take a closer look.


I Unboxing

Classic ANKER package design featuring a clean white box with blue accents.

Specifications on the back.

Patterned surface, nice touch.

Model: B2570. Input: 5V2.4A, 9V2A, 12V1.5A. Wireless output: 5W, 7.5W, 10W. USB output: 5V/0.5A. Size: 210*100*14.6mm (8.27*3.94*0.57in). Weight: 180g (6.35oz). Made in China.

A blue inner box inside the packaging.

Package contents: wireless charging pad, QC3.0 charger, Micro USB cable, user manual, warranty card.

The included Micro USB cable with 2M length and a cable tie.

The included Anker QC3.0 charger with Anker’s signature blue USB-A port and Qualcomm’s QC3.0 logo.

Charger model: ASUC71i-050912300. Input: 100-240V, 50/60Hz, 0.7A. Output: 5.0V3.0A, 9.0V2.0A, 12.0V1.5A;Made by Shenzhen Aquilstar Technology Co., Ltd.

The wireless charging pad comes in white in the shape of a track.

Compared to a 1 Yuan RMB coin. It is slim and rounded.

The bottom.

It is Qi certified.

Micro USB input port. We definitely prefer a USB-C port.

On the left is the wireless charging area for phones. There is an Anker logo in the center. There is a small circular LED indicator on the lower right side of the wireless charging area.

On the right is the stand for Apple Watch which is hollowed out for easy installation. The product needs to be used with the Apple Watch Magnetic Charger to USB Cable (1m) that comes with the Apple Watch.

Taking a look at the back cover with OPEN lettering on the left. Simply push it to the left and slide open the back cover.

Non-slip rubber pads on the corners.

Open the back cover and look at the structure inside.

There are corresponding slots and trunking to contain the Apple Watch charging cable inside.

An illustration of the installation guide for the Apple Watch charging cable is printed on the right.

This is how the Apple Watch Magnetic Charger to USB Cable (1m) is fitted inside.

Put the back cover back and we are done.

You can fold down the watch stand for easy storage, or flip it up to obtain the perfect angle for the Apple Watch’s Nightstand Mode.

Perfect for the Apple Watch’s Nightstand Mode.

Using the wireless charging aging tester, we read a “PPP” which means it passed the 5W, 7.5W and 10W wireless charging. So it supports normal 5W, Apple 7.5W, and Samsung 10W wireless charging.

It starts charging instantly when we put the phone on top. Our Samsung Galaxy S10+ shows it gets fast charging.

It can charge a phone and an Apple Watch simultaneously.


II Teardown

There is a blue USB port hidden inside the charger, which is used to connect the Apple Watch charging cable.

Plug the Apple Watch charging cable in here.

The plastic bracket has a damping structure for easy adjustment to different positions.

Open the wireless charger, we can see the wireless charging coil on the left and the wireless charging circuit board in the middle.

There is an ANKER logo on the board and a CBB resonant capacitor in the lower left corner.

Compared to a 1 Yuan RMB coin.

MPS MP2229 synchronous rectifier buck converter for fixed frequency regulation.

EMB09P03 MOSFET for switching 5V input.

Southchip SC8103 synchronous rectified buck converter steps down the input for the Apple Watch charging cable.

Small signal triode.

Micro USB input port with a blue plastic core.

ANKER logo on the PCB.

Data cable pad for applying voltage.

DC input pad.

Pins for voltage output and data, respectively, and the data pins are used to trigger fast charging.

ZZEC resonant capacitor designed for wireless charging by JURCC.

All the components.


III Conclusion


The Anker PowerWave+ Pad with Watch Holder can simultaneously charge an Apple Watch and a phone. The bracket supports different positions so you can fold down the watch stand for easy storage, or flip it up to obtain the perfect angle for the Apple Watch’s Nightstand Mode. It makes use of your existing Apple Watch Magnetic Charger and simplifies your wireless charging situation with minimalistic aesthetics. However, for a single-coil wireless charging pad, the asking price is pretty steep.


Pros:

Beautiful design and high quality components.

Makes use of your existing Apple Watch Magnetic Charger.

Includes a QC3.0 charger.


Cons:

Expensive for a single-coil wireless charging pad ($59).

Dated Micro USB port.
