Introduction

Recently, ChargerLAB got a 260W DC to USB Power Extender from SlimQ. It has two USB-C ports, two USB-A ports, and one DC socket. It has a maximum output power of 260W. Next, let's do some tests to see its charging performance.

Product Appearance

The SlimQ 260W DC to USB Power Extender comes in simple black paper packaging.

The box contains the power extender, a silicone protective case, and some documents.

Its shell is made of blue-black aluminum alloy and uses an anodizing process to ensure excellent heat dissipation performance and a smooth feel. There are two USB-C output ports on one side, two USB-A outputs, and a DC input port on the other.

Each USB-C port has a maximum output of 100W, and the plastic sheets are black.

The maximum output power is marked on the back.

The other side has a DC output port in the middle (input voltage range is 5-24V) and USB-A output interfaces on both sides, with a maximum output of 30W and orange plastic sheets.

The output power is also marked on the back.

The width is about 48.42 mm (1.91 inches).

The length is about 71.93 mm (2.83 inches).

The thickness is about 19.85 mm (0.78 inches).

And the weight is about 65.3 g (2.3 oz).

The weight including the silicone protective case is 77.7 g (2.74 oz).

That's how big it is in the hand.

Protocol Test

The DC power output port specification is 5.5mm * 2.5mm (input voltage range is 5-24V). Next, we use the SlimQ 330W charger to power the extender for the protocol test.

USB-C1/C2 

ChargerLAB POWER-Z KM003C shows the USB-C1/C2 port can support QC3+, FCP, AFC, PD3.0, PPS, QC5, DCP, and Apple 2.4A charging protocols.

And it has five fixed PDOs of 5V/3A, 9V/3A, 12V/3A, 15V/3A, 20V/5A, and two sets of PPS, which are 3.3-11V/3A and 3.3-21V/3A.

USB-A1/A2 

ChargerLAB POWER-Z KM003C shows the USB-A1/A2 port can support QC3.0, FCP, SCP, AFC, DCP, and Apple 2.4A charging protocols.

Compatibility Test

USB-C1/C2

Use it to charge the iPhone 16, the power is about 14.88V 1.53A 22.72W.

Use it to charge the MacBook Pro 16 M1 Max, the power is about 19.76V 4.64A 91.71W.

As you can see, there is no compatibility issue. Most phones can reach about 9V. Some phones with good compatibility can reach a voltage of more than 15V.

We have compiled the test results into a bar chart. Most phones can maintain a power of 11-27W. Some phones that support PD or PPS protocols can reach a power of 30-54W.

USB-A1/A2

There is no compatibility issue. Most phones, except Apple and Red Magic phones, can reach a voltage of 9V.

The highest charging power is 20.81W of Huawei Pura70 Pro+, followed by 19.18W of Xiaomi 14 Ultra.

Multi-port Simultaneous Output Test

Use the two USB-C ports of the power extender to charge two laptops at the same time, with charging power of 92.05W and 95.22W, respectively.

Use the power extender's two USB-C ports and one USB-A port to charge two laptops and a phone at the same time, with charging power of 92.09W, 88.47W, and 22.89W, respectively.

Use the two USB-C ports and two USB-A ports of the power extender to charge two laptops and two mobile phones at the same time. The charging power is 92.20W, 95.49W, 7.29W, and 7.27W respectively.

Full Charging Test

Next, we'll use the USB-C port of the SlimQ 260W DC to USB Power Extender to fully charge the MacBook Pro 16 M1 Max.

The power extender and the MacBook 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 20V. The charging curve can be divided into four parts. In the first part, the peak power stayed at 93W for the first 39 minutes. Then, the power gradually drops to 67W and 43W in turn. The final part begins at one hour and 6 minutes, the power slowly drops to almost zero. It takes 2 hours and 3 mins to be fully charged.

We also turn it into another curve. The power extender can charge the MacBook Pro 16 M1 Max to 50% in 32 mins. And it can reach 80% in 56 mins, 100% in 2 hours and 3 mins.

Temperature Test

Then, we are going to the temperature test. We put the power extender into a 25°C (75℉) thermotank. And recorded the highest temperature on the front and back under the load of 20V5A after one hour.

After one hour, the maximum temperature on the front is about 51.2℃ (124.16 ℉).

The maximum temperature on the back is about 51.4℃ (124.52 ℉). The temperature on both sides is almost the same. The silicone protective cover it comes with can reduce the perceived temperature when you touch it.

Summary of ChargerLAB

SlimQ 260W DC to USB Power Extender is made of aluminum alloy. It has two USB-C and two USB-A ports with independent output. It supports 5-24V DC input and is compatible with more power devices. It has a maximum output power of 100W + 100W + 30W + 30W.

The USB-C1/C2 port can support QC3+, FCP, AFC, PD3.0, PPS, QC5, DCP, and Apple 2.4A charging protocols. And it has two sets of PPS, which are 3.3-11V/3A and 3.3-21V/3A. It has good compatibility and can charge most phones, tablets, thin and light laptops, and other devices. In the full charging test, it took 32 minutes to charge the MacBook Pro 16 M1 Max to 50%, and it fully charged in about 2 hours and 3 minutes. Overall, the SlimQ 260W DC to USB Power Extender is very good in terms of portability and practicality.
