Gendome Micro45 15000mAh LiFePO4 Power Bank Teardown: INJOINIC IP5385 SoC and Gotion 32135 Cells
2026-10-06 · Compiled by Best IT Parts from public industry reporting
A teardown of the Gendome Micro45, a 15000mAh lithium iron phosphate (LiFePO4) power bank with 96Wh of battery energy (15000mAh at 6.4V) and a 15300mAh rated capacity at 5V/3A. It carries 3C safety certification and meets airline carry-on requirements. The port layout is 3C1A: USB-C1 (input/output), USB-C2 (output), USB-A (output) plus a built-in 0.75-meter retractable USB-C cable. USB-C1 and the retractable cable each deliver up to 45W (20V/2.25A), while USB-C2 and USB-A are limited to 18W and combined multi-port output is capped at 5V/3A. A top-mounted LED light bar and an LED percentage display complete the feature set.
Measured dimensions are 162.38 by 80.39 by 51.99mm at 800.8g. Protocol testing on USB-C1 shows QC3.0, FCP, SCP, AFC, PD3.0, DCP and Apple 2.4A, with PDOs of 5V/3A, 9V/3A, 12V/3A, 15V/3A and 20V/2.25A plus PPS ranges of 3.3-11V/3A and 3.3-16V/3A; the 45W-capable retractable cable reports the same PDO set.
Internally, two Gotion IFR32135 cylindrical LiFePO4 cells — 15Ah each at 3.2V nominal — sit in a plastic bracket with an NTC thermistor for temperature monitoring, their nickel strips ultrasonically welded to the PCBA. Main control is an INJOINIC IP5385 synchronous buck-boost power-bank SoC that integrates the fast-charge protocol engine, MCU and synchronous buck-boost controller. It supports 2-4 series Li-ion and LiFePO4 packs and, with external MOSFETs and an inductor, forms a 65W bidirectional fast-charge design covering UFCS, PD3.0, PPS, SCP and FCP.
The power stage uses four APM AP75N03DF buck-boost MOSFETs (30V, 5.8mohm, PDFN3x3), with APM AP60N03BDF (30V, 8.0mohm, PDFN3x3) as the VBUS switches for USB-C1, USB-C2, USB-A and the retractable-cable rail. A SOT23-6 lithium protection IC marked 22AA, backed by AP75N03DF protection FETs, handles pack safety, and an 188 LED digital tube displays charge status.
