A charging system includes a first device; a second device; and a power adjustment device including a DC-to-DC conversion unit; and a micro-control unit for receiving a charging instruction, a first power information of the first device and a second power information of the second device and performing the following steps: controlling the DC-to-DC conversion unit to convert a first supply current received by the first device into a first charging current according to the first power information and the second power information when the charging instruction instructs the first device to charge the second device; and controlling the DC-to-DC conversion unit to convert a second supply current received by the second device into a second charging current according to the first power information and the second power information when the charging instruction instructs the second device to charge the first device.

Power adjustment device and charging system

An adjustable screen lift arm includes a support frame assembly with a frame base, a balance adjustment mechanism including a gear set consisting a drive gear and a sector-like driven gear, a gear rack meshed with the drive gear and a spring connected between the frame base and the driven gear, and a holder block assembly has a holder block body that combined with the gear rack and a first sliding rail, the other side combined with a second sliding rail. When the holder block body is moved vertically, the gear rack rotates the drive gear, causing the driven gear to stretch or compress the spring so that the arm of force is relatively changed to offset the spring force of the spring, enabling the holder block assembly to be freely adjusted to the desired elevation and then automatically positioned.

Adjustable screen lift arm

An adjustable desktop assembly includes a base frame having two inwardly tilted sliding plates at two opposite lateral sides thereof and a mounting unit at a rear side thereof for fastened to an external support frame assembly, an adjustment mechanism including a sliding base coupled to the bottom side of the base frame and an adjustment unit, two clamping plates bilaterally mounted in the sliding base, a lead screw mounted in the adjustment unit, and a pressure block affixed to the lead screw and movable with the lead screw between a locking position where the pressure block is abutted against an abutment block of the adjustment unit to lock a desktop to the base frame and an unlocking position where the pressure block is released from the abutment block for allowing adjustment of the forward and backward position of the desktop relative to the base frame.
