Anker charging accessories are up to 40 percent off in one-day Amazon sale

You can get Anker's power banks, cables and other charging accessories for up to 40 percent off only for today at Amazon. The brand's pint-sized 30-watt Nano II charger that's powered by GaN technology, for instance, is currently listed for $23.80. That's the lowest price we've seen for the device, which typically sells for $30. Since it's powered by GaN technology that replaces silicon with gallium nitride, Anker was able to design the USB-C device to be as big as a phone charger even though it can also power laptops like the MacBook Air and tablets like the iPad Pro.
