High-Quality USB Power Supplies for Optimal Power Supply
Raspberry Pi USB Power Supplies
An adequate power supply is essential for your Raspberry Pi and other mini-computers. At Berrybase, you can find various powerful USB power adapters to ensure reliable power supply.
For a small price, you can get, for example, the official Raspberry Pi power supply with 3.0A / 5.1V. Thanks to the highly efficient power supply with USB-C output, you can reliably power your Raspberry Pi 4 at all times. The USB power adapter, available in black or white, comes with a 1.5m long cable and features short circuit, overload, and overvoltage protection.
If you want to charge multiple devices with a single power supply, we recommend the USB 3 port power supply or the USB 4 port power supply with 5V / 5.0A from the manufacturer OTB. The powerful product offers USB sockets for three or four devices. Each port delivers up to 2.4A output current and auto-ID. With this innovative function, the adapter detects directly how much power is needed to fully charge the respective device. This is followed by an automatic optimization of the required power - for more efficiency during the charging process.
Do you also work with your Raspberry Pi abroad? Then a USB-C charger with various interchangeable input connectors is essential. At Berrybase, you can find a reliable USB-C power supply for the Raspberry Pi 4 with 5.1V / 3.0A and four connectors that you can use in Europe, the United Kingdom, the United States, and Australia. Features such as overvoltage protection of up to 10V DC and overcurrent protection with a maximum of 5A and automatic recovery function make the USB-C charger an absolute top product. If you only use your mini-computer domestically, the official Raspberry Pi USB-C power supply in the EU version, available in black and white, is sufficient.
Are you looking for an internationally usable Raspberry Pi power supply for the 3 model? In this case, the official Raspberry Pi micro USB power supply with interchangeable AC plug is a good choice. The charger comes with four interchangeable adapters and is therefore a solid addition to your Raspberry Pi 3, especially when traveling. This USB power supply also comes equipped with short circuit, overload, and overvoltage protection and also scores points with low standby power consumption.
But Berrybase's range of products not only includes USB power supplies. You can also find other products that provide energy to your modules, including innovative solar panels, practical dual USB car chargers, powerful power banks in various designs, or even Li-ion battery HATs for your Raspberry Pi.
What should I consider when buying a power supply for my smartphone?
When buying a power supply for your smartphone, you should consider the following:
- Compatibility: Check if the power supply is compatible with your smartphone model. You can find this information in your smartphone's user manual.
- Output power: Make sure that the output power of the power supply matches the requirements of your smartphone. Most smartphones require an output power of 5V and 1A or 2A. Also, check if the power supply has a USB port that is compatible with your smartphone's cable.
- Quality: Look for the quality of the power supply and choose a model from a reputable manufacturer. Cheap power supplies can damage your smartphone and even be dangerous.
- Additional features: Some power supplies have additional features like fast charging technology or multiple USB ports that allow you to charge multiple devices simultaneously.
- Safety features: Make sure that the power supply has adequate safety features like overload protection, short circuit protection, and overheating protection to ensure that it is safe to use.
- Certifications: Look for certifications like CE, FCC, and RoHS that confirm that the power supply meets safety and environmental standards.
What power supply do I need as a charger for faster charging?
PD, QC3.0, and QC4.0 are different standards for fast charging technologies on power supplies and mobile devices. Here is a brief explanation of the differences:
- PD (Power Delivery): PD is a standard developed by the USB Implementers Forum (USB-IF) that allows devices to be charged at higher power levels over USB. With PD, devices can be charged up to 100 watts (20V/5A), enabling faster charging. PD is a flexible technology that allows devices with different power requirements to be effectively charged.
- QC3.0 (Quick Charge 3.0): QC3.0 is a technology developed by Qualcomm that allows compatible devices to be charged at higher speeds. QC3.0 is backwards compatible and works with older versions of the Quick Charge standard. QC3.0 allows for faster charging speeds through higher voltage (up to 20V) and increased current (up to 6A).
- QC4.0 (Quick Charge 4.0): QC4.0 is the latest version of Qualcomm's Quick Charge standard. It offers some improvements over QC3.0, including more efficient charging that can extend battery life and higher power output (up to 100W). QC4.0 is also backwards compatible and supports older versions of the standard.
Overall, PD, QC3.0, and QC4.0 offer different options for fast charging of devices and are compatible with different devices and power supplies. It is important to note that not all devices are compatible with all standards, and using a wrong charger can damage the device. So, it is important to choose the right charger for each device.
What is a Lightning charging cable/power adapter?
Apple iPhones support a fast charging technology called "Lightning" which represents the "USB Power Delivery" (PD). With a USB-C to Lightning cable and a compatible power adapter (such as the Apple 20W USB-C Power Adapter), iPhones with PD support can be charged quickly.
Depending on the iPhone model, the supported PD power levels can be different. For example, the iPhone 8 and higher support a maximum power of 18 watts (9V/2A), while the iPhone 12 and higher support a maximum power of 27 watts (9V/3A).
It is important to note that older iPhones like the iPhone 7 and earlier do not support the full speed of USB PD and therefore cannot be charged as quickly as newer models. Also, you need a compatible power adapter and a cable that supports PD to use the fast charging technology.
