Injoinic Technology is a Chinese power management and power-bank SoC designer founded in 2014 and listed on the Shanghai Stock Exchange STAR Market (ticker 688209) since its 2022 IPO. Injoinic specializes in single-chip solutions for portable power: its IP-series power bank ICs integrate lithium battery charging, synchronous boost conversion, battery-level indication, button control, and multi-layer protection into one package — the architecture behind a large share of the power banks manufactured in Shenzhen. The IP5328P is a representative part: a complete power bank solution delivering 5 V output at up to 2.4 A with integrated charge management and LED fuel gauge, letting manufacturers build a certified power bank around one IC, an inductor and a few passives. Injoinic also supplies fast-charge protocol ICs (PD/QC) and wireless charging parts. Our Shenzhen warehouse stocks the IP5328P from Injoinic authorized distribution, with full-load output and fuel-gauge verification on every lot.

Sourcing from Injoinic – FAQ
Is Injoinic a legitimate manufacturer?
Yes — Injoinic Technology Co., Ltd. was founded in 2014, is headquartered in the Shenzhen/Zhuhai technology corridor, and listed on the Shanghai STAR Market in 2022 (ticker 688209). The company holds hundreds of power-management patents and supplies SoCs to mainstream power bank and charger OEMs. Its IP5328P and siblings are original Injoinic designs — the clone risk in this category is fake modules using relabeled dies, not fake company claims.
What exactly does the IP5328P integrate?
The IP5328P is a power bank system-on-chip: synchronous boost converter generating 5 V at up to 2.4 A from a single lithium cell, integrated battery charger, battery fuel gauge driving 1-4 LED indicators, push-button power control with auto-shutdown at light load, and protection covering over-charge, over-discharge, over-current, over-temperature and short circuit. External parts are minimal — an inductor, sense resistor, LEDs and passives — which is why it dominates low-cost power bank BOMs.
How do you screen IP5328P stock for counterfeits?
We buy only through Injoinic's authorized channel, then bench-verify lots: full 2.4 A load test measuring output regulation and efficiency, charge-cycle test confirming proper CC/CV termination, LED fuel-gauge threshold check, and light-load auto-shutdown behavior. Relabeled or clone dies typically sag below 5 V at rated load or run hot — both caught by this screening. Original Injoinic tape-and-reel packaging with lot codes is preserved through shipment.
What is the lead time for Injoinic parts?
Injoinic is a Shenzhen-based STAR Market company with domestic authorized distribution delivering in 1-2 weeks. Our Shenzhen warehouse holds IP5328P stock for same-day to 2-day shipment on quantities under 10,000 pcs, and we can arrange factory-direct orders with C-of-C for power bank OEM production runs.
