Introduction

This time, ChargerLAB got a magnetic wireless power bank from Durex. Its battery capacity is 10000mAh. In addition to wireless charging, it can also support PD 20W charging. Next, let's do some tests to see how its charging performance is.

Product Appearance

The box is overall gray. The logo of Durex is printed on the bottom of the front.

The specs info are printed on the back of the box, we'll talk about it later.

The box contains the magnetic power bank, a USB-A to USB-C cable, and some documents.

The case is made of fire-retardant material. The surface is painted with metallic paint, giving it a full texture. There is also a large black plastic panel on the front with the word "20W" printed on it.

There is a circular display on the lower right corner and it can show the remaining power.

The side case adopts an integrated design with sharp edges.

The wireless output panel is made of silicone. There is a built-in magnetic ring, which is similar to the MagSafe.

The specs info are also printed on the wireless charging panel. Model is Q9. The battery capacity is 10000mAh 3.7V 37Wh. The rated capacity is 5500mAh. It can support an input power of 10W by Lighting port. The maximum input power of the USB-C port is 18W. It can support output of 5V/2A, 9V/2.22A, and 12V/1.5A.

It is equipped with a Lightning input port, a 20W USB-C port, and a power button.

Here is the included USB-A to USB-C cable.

The length of the power bank is about 103 mm (4.055 inches).

The width is about 68 mm (2.68 inches).

The thickness is about 19 mm (0.75 inches).

And the weight is about 200 g (7.055 oz).

It can be easily held in one hand and is convenient to be carried out.

How well does it fit with iPhones?

We selected several iPhones for testing to see how well it is compatible with iPhones.

It is wider than the iPhone 13 mini, but it does not block the camera after being adsorbed.

The magnetic power bank is paired with the iPhone 15. The power bank and the phone are basically flush, and there is no obstruction on the camera module.

Use it to charge the iPhone 15 Plus, it will not block the camera.

When paired with an iPhone 15 Pro, it is close to the camera but does not block it.

Use it to charge the iPhone 15 Pro Max, it will not block the camera.

It can be firmly attached to the phone and will not fall off even if it is turned upside down.

Protocol Test

Next, we will do a compatibility test on its USB-C port.

The ChargerLAB POWER-Z KM003C shows the USB-C port can support FCP, SCP, AFC, QC3.0, QC4+, SFCP, PD3.0, DCP, SAM 2A, Apple 2.4A, and PPS charging protocols.

And it has three fixed PDOs of 5V3A, 9V/2.22A, 12V/1.67A, and two sets of PPS, which are 5-5.9V/3A and 5-11V/2A.

Charging Test

Now, let's take a look at its charging test.

Compatibility Test

It supports magnetic wireless charging, but can also be charged via the USB-C port. Let's take a look at the charging compatibility.

The ChargerLAB POWER-Z KM003C shows that when the USB-C port is connected to the iPhone 15 Pro Max, the charging power is about 8.98V 2.16A 19.4W.

As you can see, there is no compatibility issue. Most phones can reach about 8V and 9V. And game consoles, tablets, and laptops can reach about 12V. The maximum charging power can reach 19.4W.

We have compiled the test results into a bar chart. The devices that can support the PD protocol can get a higher charging power, the charging power remains in the range of 17 to 20W. The charging power of a few devices is in the range of 11 to 15W.

Wireless Charging Test

After testing, it can magnetically wireless charge iPhone 15 and other models.

After testing, it can also provide magnetic wireless charging for the vivo X100 Pro.

After placing the Xiaomi 13 Ultra on the wireless charging panel, the phone displays the wireless charging UI and starts charging.

Full Charging Test

Next, we'll use the Apple 35W charger to fully charge the Durex 10000mAh magnetic power bank via the USB-C port.

The charger and the power bank will be put into a 25°C (77℉) thermotank throughout the test. Here is the charging curve made by the PC software of KM003C.

The voltage is always around 9V. The charging curve can be divided into two parts. In the first part, the peak power stayed at 18W for the first 38 mins. But at 8 to 10 minutes the power dropped to 4W. Then, the power slowly drops to almost zero. It takes 3 hours and 31 mins to be fully charged.

We plot it into another curve to see how fast it can be. It can be charged to 50% in 45 mins and 80% in 1 hour and 37 mins. And it can be fully charged in 3 hours and 31 mins.

Then, use the Lighting port to fully charge the Durex 10000mAh magnetic power bank.

The voltage is always around 5V. The charging curve can be divided into two parts. In the first part, the peak power stayed at 9W for the first 1 hour and 44 mins. Then, the power gradually drops to almost zero. It takes 4 hours and 15 mins to be fully charged.

We plot it into another curve to see how fast it can be. It can be charged to 50% in 1 hour and 27 mins and 80% in 2 hours and 25 mins. And it can be fully charged in 4 hours and 15 mins.

Discharging Test

Let it continue to output at different currents and voltages until the power is exhausted, and record the data. The test results are as follows.

First, let the power bank continue to output at a power of 5V3A 15W, and the power was exhausted in 1 hour and 6 mins. The released battery energy is about 16.39Wh, so the efficiency of the power bank when outputting at 5V3A 15W is about 16.39/37=44.3%.

Let it continue to output at 9V2.22A 20W, the output is interrupted at 26 mins. The released battery energy is about 8.46Wh, and the remaining power is 35%.

Let it continue to output at 12V1.67A 20W, the output is interrupted at 26 mins. The released battery energy is about 8.73Wh, and the remaining power is 40%. We infer that the output may have stopped due to overheating of the battery core.

Temperature Test

Then, we are going to the maximum temperature test. We put the power bank into a 25°C (75℉) thermotank. And recorded the highest temperature on the front and back after charging at 12V1.67A 20W for 20 mins.

After 20 mins of charging, the maximum temperature on the front is 36 ℃ (96.8 ℉).

And the maximum temperature on the back is 37.7 ℃ (99.86 ℉). The heat is mainly concentrated on the magnetic ring.

Summary of ChargerLAB

The Durex 10000mAh Magnetic Power Bank has a fire-retardant case and is coated with metallic paint. The wireless output panel is made of silicone and has a built-in magnetic ring. The battery capacity is 10000mAh. The USB-C can support an input of 18W and an output of 20W. The maximum wireless output power is 15W, which meets the charging needs of Apple and Android phones.

It can be charged to 80% in 1 hour and 37mins, but it will take 3 hours and 31 mins to be fully charged. Trickle charging takes a long time. When it outputs at 15W, the efficiency is 44.3%, which is low overall. When outputting at 20W, the power may be interrupted due to high temperature. The power bank is well compatible with various iPhone models and does not block the camera. There is no problem with the compatibility of wired charging, and most of the tested phones can reach above 15W.
