Power & Charging
Power banks, chargers, cables — the category where cell grade fraud is most common. I verify every mAh claim.
Power Bank
MagSafe, high-capacity, fast-charge, mini. BOM driven by: cell grade (A vs B vs recycled), PCB BMS protection, housing durability, PD protocol chip.
Inquire →Wall Charger
GaN, multi-port, fast-charge adapters. Key costs: GaN chip vs silicon, port count, safety certifications (CE, FCC, UL).
Inquire →Charging Cable
USB-C, Lightning, multi-head cables. BOM focus: copper wire gauge, connector durability rating, data transfer speed chip.
Inquire →Wireless Charger
Qi-certified charging pads and stands. Critical: charging coil quality, heat dissipation design, foreign object detection chip.
