TEARDOWNTeardown: MIIIW M310 Pro 45W Power Bank Uses IP5385 SoC
A 10,000mAh pack with retractable USB-C cable, 45W single-port output and an IP5385 controller that integrates UFCS alongside PD3.0 and PPS.

MIIIW has released the M310 Pro digital-display power bank, model iPB1045, built on a 10,000mAh pack formed from two 21700 cells and rated at 36Wh, or 5,500mAh at 5V/3A. A one-piece aluminium housing carries a retractable USB-C cable, and together with the fixed USB-C and USB-A ports the unit can charge three devices at once.
Single-port output is rated 45W maximum. Both USB-C paths list fixed PDOs of 5V/3A, 9V/3A, 12V/3A, 15V/3A and 20V/2.25A, PPS at 3.3-11V/3A and a 45W PPS range of 3.3-20V/2.25A; the fixed port adds a 3.3-11V/4.1A PPS step. The USB-A port covers QC3.0, FCP, SCP and AFC but not PD. Input on either USB-C path is capped at 12V/2.5A, and multi-port use falls back to 5V/3A.
Measured at 90.19 x 49.45 x 37.22mm and 228.3g, the pack charged a Xiaomi 17 Pro Max at 16.6V/2.1A, or 36W, triggering the phone's turbo-charge mode. A three-digit LED display behind the front panel shows remaining capacity in percent and is woken by a button on the base.
Inside, a single board is fed by two INR21700-5000 cells joined by nickel strip, insulated with fish paper and fitted with an NTC thermistor. The controller is an IP5385 SoC that integrates UFCS with QC2.0/3.0, SCP, AFC, FCP, PD3.0 and PPS, driving a four-MOSFET buck-boost stage of IP04N03B devices (30V, 3.1mOhm) around a 4R7 alloy inductor, with LT7904 parts handling VBUS switching.
Protection combines a CM1020-MA two-cell safety IC in SOT23-6, a dual N-channel LT2002EFO-X MOSFET pair rated 20V and 46A continuous at 4.5mOhm typical on-resistance, and an HY2212-BB3A balancer across the series stack. The result is a compact reference for a 45W three-output pack built on a single integrated SoC.
