The Best Portable Multi USB Charger for Laptops and Phones
Posted by COOL GADGET
Are you still struggling with the need to carry multiple chargers to charge your phone and laptop when you travel? Are you still using a bulky traditional laptop charger? Try Cool Gadget 67W USB-C Power Adapter. It is a very small size, but can provide fast charging for your laptop and phone (Android & Apple) at the same time, replace all your big and slow chargers with this one!
Multi-USB charger with fast and powerful charging capabilities
Cool Gadget 67W USB-C Power Adapter is a USB charger with powerful fast charging capability. It provides two charging ports (USB A & USB C) that can deliver up to 67w of fast charging for two devices simultaneously. In Cool Lab’s test, it only took 30 minutes to charge iPhone14pro’s battery from 1% to 54%, which is the same as the charging effect of Apple’s official 20w charger.
Furthermore, the Cool Gadget 67W USB-C Power Adapter also offers fast charging for laptops, Android devices, and more. It can deliver up to 67w for laptops and 25w for Android devices that support PD charging protocol. In Cool Lab’s test, it charged a laptop (ThinkPad L14) to 48% in just 30 minutes, far exceeding the official 45w charger. Its powerful charging capability and compatibility are important reasons why we recommend it.
The most compact and portable multi-USB charger
What’s even more incredible is that the Cool Gadget 67W USB-C Power Adapter has such a powerful charging ability while being extremely small in size. It is almost the smallest high-power (over 60w) charger you can find on the market.
As you can see from our photos, it is only slightly larger than the Apple 20W USB-C Power Adapter, and much smaller than the regular laptop charger (ThinkPad 45w USB-C Power Adapter), as well as other brands of high-power chargers (Ugreen 65W GaN charger).
In terms of weight, the Cool Gadget 67W USB-C Power Adapter (85g / 0.19lb) is heavier than the Apple 20W USB-C Power Adapter (58g / 0.13lb), but much lighter than the high-power chargers like the ThinkPad 45w USB-C Power Adapter (318.9g / 0.70lb) and the Ugreen 65W GaN charger (130g / 0.29lb).
So far, the Cool Gadget 67W USB-C Power Adapter is still the most compact and portable high-power multi usb charger we know of. It is perfect for you to carry when you travel. With it, you don’t need to bring a bulky laptop charger anymore.
❓Why is the Cool Gadget 67W USB-C Power Adapter so small in size while having a high power charging capability?
1. Cool Gadget 67W USB-C Power Adapter uses advanced GaN material to prepare the power device. The use of GaN materials has the following advantages:
- High conversion efficiency: The on-state resistance of GaN power devices with the same rated voltage is 3 orders of magnitude lower than that of ordinary chargers with Si power devices, greatly reducing the conduction loss of switching.
- High working frequency: GaN power devices have small parasitic capacitance, and their working efficiency can be increased by at least 20 times compared to ordinary Si power devices, greatly reducing the size of energy storage components such as capacitors and inductors in the circuit, thereby reducing the device size by multiples and saving precious raw materials such as copper.
2. The Cool Gadget 67W USB-C Power Adapter has an excellent circuit board design that cleverly stacks the electronic components, which makes it much smaller than ordinary GaN chargers.
Eco-friendly Multi USB Charger
The Cool Gadget 67W USB-C Power Adapter is also an eco-friendly and energy-efficient multi-USB charger. Due to its GaN material, the Cool Gadget 67W USB-C Power Adapter's carbon footprint is about 10 times lower than traditional Si device chargers, effectively reducing carbon emissions.
It is estimated that if data centers around the world using si-chip devices were to switch to GaN power-chip devices, data centers around the world would reduce energy waste by 30-40%. This is equivalent to 100 MWh of solar energy and 125 million tons of CO2 emissions saved. Whether you choose Cool Gadget or not, we strongly recommend you use GaN material chargers and contribute to the ecology of the earth together.
CoolGadget 67W USB-C Power Adapter Charging Test
I. USB C charging test
a. Charging test for Apple phones
We used the USB C port of the Cool Gadget 67W USB-C Power Adapter to charge the Apple iPhone 14 pro. From the test data below, you can see that the charging power can initially maintain around 20w, and it only takes 30 minutes to charge the phone from 1% to 54% of the battery.
The 20w charging power lasts until the phone battery is about 75%, then the charging power starts to drop (to protect the battery), and it fully charges the phone in the 100th minute. The charging efficiency is no different from the official Apple charger.
b. Charging test for Android phones
We used the USB C port of the CoolGadget 67W USB-C Power Adapter to charge an Android device (POCO F5) with a large 5000mAh battery. You can see that the charging power can be maintained in the range of 23-25w, and it charges the phone from 1% to 52% of battery in 30 minutes. It fully charges the phone in the 76th minute, which is very impressive.
c. Charging test for laptop
We used the USB C port of the Cool Gadget 67W USB-C Power Adapter to charge a laptop (ThinkPad L14) with a large 45Wh battery. You can see that the charging power can maintain around 60w, and it charges the ThinkPad L14 from 1% to 50% of the battery in 30 minutes.
It charges the laptop to 95% close to full in the 70th minute, then enters a trickle charging time of about 15w. It fully charges the ThinkPad L14 in the 86th minute, which is very impressive and better than the official 45W charger.
II. USB A charging test
We used the USB A port of the CoolGadget 67W USB-C Power Adapter to charge Android phones (POCO F5) and Apple devices (iPhone 14 pro) separately. The charging power for Android devices fluctuates between 16w and 18w, while the charging power for Apple devices fluctuates between 8w and 10w.
- Apple devices do not support the fast charging protocol of USB A port.
- Laptops are not supported for charging with the USB A port protocol.
III. Dual port charging test (USB A &USB C)
We tested the Cool Gadget 67W USB-C Power Adapter using both USB C & USB A ports to charge a laptop (using USB C) and an Android device (using USB A) at the same time and could see the total power of the charger floating around 65w.
The Cool Gadget 67W USB-C Power Adapter is an amazing product that provides fast and stable charging for all of the devices we tested. And it's small enough that it doesn't take up as much outlet space as other chargers. It will meet your charging needs for almost any device, whether for everyday use or on the go. If you are looking for a suitable multi-port USB charger, I think the CoolGadget 67W USB-C Power Adapter is a good choice!
