Built for electric-bike charging

This compact adapter plugs into a bike’s 12-90 V DC system and delivers a steady 5 V at 2 A through its USB ports. It is made for riders who need reliable phone, tablet or watch charging while on the move.

Fits between bike power and USB devices

The unit accepts a wide DC input range and converts it directly to USB output without a separate power brick. Its small plastic body measures roughly 75 by 40 by 30 mm, leaving handlebar or frame space free for other accessories.

LED voltage monitor shows real-time status

The display reads low voltage at 4.75 V, normal at 5.2 V and high at 6.0 V so you can spot supply issues instantly. Built-in protection guards against over-charging, over-current and over-heating during normal use.
