Review on 🔌 ProTechTrader 5V 2.5A Raspberry Pi & Orange Pi Power Supply SBC Adapter Kit - 5.5 x 2.5mm Tip with RPI Micro USB and OPI 4.0x1.7mm Converter Tips, UL Listed by Marcus Merritt

with fork 5.5 x 2.5 . This 2.5A power adapter works great. Many other Revain supplies advertise 5.5x2.5 but the description says 5.5x2.1 - be careful when ordering. The advantage of this power supply is that it is equipped with a micro USB B male adapter. With an adapter, it can be used to power your Raspberry Pi computer! Alternatively, many active USB hubs also use a micro USB B connector for power. There is also an adapter for an Orange Pi computer - I don't use it now but maybe in the future. In any case, this is a very versatile power supply. highlighted.
