In this week’s BBC News UK Power of the Hour, the BBC’s power expert Dr David Curnow tells us which USB-to-AC adaptors can provide the best power.
Read more The USB-c adaptors offer a USB 2.0 port, while the Lightning-to USB-D adaptors have a USB 3.1 connector.
These adaptors are more expensive than the USB-3.1 ports, but have the advantage of being able to charge more devices, and they work better than the standard USB-M to USB-B adapters.
If you have a laptop that’s not USB-connected, you can still plug a Lightning cable into the adapter to use it to charge other devices, or you can simply buy a USB to USB adapter to make this process even easier.
The USB port is only used by some laptops, such as the Dell XPS 13, so if you’re looking to charge a larger range of devices, the USB 2 port is the most likely option.
For a laptop or desktop PC, USB-USB to Lightning adapter The USB to Lightning to USB Adapter offers a USB 1.1 port, USB 3, USB 2 and a micro-USB port.
It works with most laptops, desktop PCs and monitors.
The micro-usb port is usually used for charging a device like a smartphone, tablet or other smaller device, and it’s not available for laptops.
However, for USB-powered keyboards, trackpads and other small USB devices, it’s a much better solution.
Read our review of the Thunderbolt to Lightning Adapter.
The Thunderbolt to USB Converter is a USB plug-and-play adaptor that offers a plug-in port that supports Thunderbolt 3, Thunderbolt 2 and Thunderbolt 1.
This adapter costs £59.99 and is available in a variety of colours.
It has a Micro USB and Micro HDMI port, so you can connect an external monitor or a small USB camera, and you can also plug an SD card reader into the converter to take advantage of the fast data transfer speeds.
If your device doesn’t have a micro USB port, you may also want to look at the USB to AC Adapter.
Thunderbolt to AC adapter This is a more traditional Thunderbolt-to -USB adapter, which can also support Thunderbolt 3.
It’s the only adapter that’s compatible with Apple’s MacBook Pro. It costs £119.99.
The cable you need to buy to use the adapter is included in the kit, but the cable you buy should be a USB Type-C to Type-A to USB Type C to USB 2 to USB 3 type-C.
It supports up to 4 Thunderbolt 3 ports at the same time, which is a significant improvement over the old USB-1 to Type C adaptor, and is the fastest way to charge up a device.
You can also connect the adapter through a Thunderbolt cable to an external Thunderbolt device, so that you can charge up other USB-equipped devices from your MacBook Pro or other devices.
However this adaptor isn’t a replacement for the Lightning to Thunderbolt Adapter.
USB-Mini to Lightning adaptor This adaptor is a small, USB to power adapter.
It charges USB devices at a rate of 5 watts per second, and does so in parallel with other USB devices.
It also supports USB 2 peripherals, but this adapto is the least powerful, so the USB Mini adapter will be best for charging larger devices, such a laptop.
The mini-USB cable you get is a cheap USB Type B to Type A to Type B cable.
It can charge devices up to 5 watts, and has a USB Micro HDMI connector.
