Disassembly report: aohi magcube 40W dual C-Port charger

2022-07-07

Although mobile phones already support dual card and dual stay, in order to separate work and life, many people will choose to use two mobile phones. Two chargers are required for charging two mobile phones at the same time, which is not only inconvenient to carry, but also takes up more sockets, which is very troublesome. At the same time, the original charger rarely adopts the design of folding pins, which is easy to scratch other items in the bag, making it more inconvenient.

Recently, aohi magcube series has launched a 40W dual port PD fast charging charger, which is equipped with folding pins. Both ports support fast charging, one port supports 40W output and PPS fast charging, two ports support 20+20w power distribution, and both ports support fast charging. Whether Android or apple mobile phones, they can get an ideal fast charging effect. Next, the charging head network will disassemble aohi this dual port 40W charger in detail to see how the interior is designed.

Aohi 40W dual port charger can be called small and exquisite. It is very easy to carry with the folding pin only 23mm thick, eliminating the inconvenience of carrying the folding pin and the cumbersome use of the two chargers. The charger supports five groups of fixed voltage gears of 5v3a, 9v3a, 12v3a, 15v2.67a and 20v2a, as well as a group of 3.3-11v3a PPS output. It has good compatibility for mainstream mobile phone fast charging.

According to the disassembly of the charging head network, aohi dual port 40W charger is internally composed of two sets of the same switching power supplies and two-way protocol chips of IC ip2738. The main control of switching power supply adopts PI inn3367c, and a single one supports 40W output. When the rating is reduced to 20W, the temperature rise is lower. The two sets of switching power supplies are controlled by ip2738 protocol chip. When single port output, two channels are connected in parallel to provide greater power. When double port output, each interface supports fast charging to achieve the ideal fast charging effect.
