DIGIFORCE Company Overview
Business Model Comprising Three Divisions
Ms.gadgetWhat kind of company is DIGIFORCE? Do they only make iPhone batteries?
MisterGadgetNot just batteries. They operate three parallel businesses: Consumer, Repair, and Reuse.
DIGIFORCE’s business is largely structured around three pillars.
1. Consumer Business — Peripherals and Compatible Batteries
They plan, manufacture, and sell peripheral devices for smartphones and PCs.
- USB Cables: Offers Apple MFi certified cables such as Type-C to Lightning, USB Type-A/C, etc.
- HDMI Cables: Slim type with two lineups: 4K compatible (HDMI 2.0) and 8K compatible (HDMI 2.1)
- Laptop/Smartphone Stands: Foldable stands made of aluminum alloy
- Compatible Batteries for Power Tools and Vacuum Cleaners: Continuously releases new compatible batteries for Makita 18V/36V/40V Max series and Dyson V6 series.
2. Repair Business — iPhone Compatible Batteries and Repair Parts
Ms.gadgetDo they also handle iPhone compatible batteries?
MisterGadgetYes, this has been a business since the company’s founding. They offer PSE-certified compatible batteries and self-repair kits with tools.
DIGIFORCE has handled replacement batteries for iPhones and other devices since its establishment.
- Offers PSE-certified iPhone compatible batteries
- Provides “self-repair kits” with tools, instructions, and magnetic sheets
- Publishes model-specific replacement manuals and videos on its official website
- In February 2024, announced the PSE Advanced Battery. This product resolves limitations such as “battery warnings” and “hidden maximum capacity” that occur when replacing non-genuine batteries in iPhone XR and later models, and is primarily provided to corporate repair service providers.
3. Reuse Business — Purchase and Reuse of Digital Devices
They also operate a reuse business that involves purchasing, refurbishing, and selling digital devices (smartphones, tablets, etc.). This forms a structure where three businesses – the Consumer Business, Repair Business, and Reuse Business – are operated in parallel.
DIGIFORCE Features: Commitment to Design
The corporate website features a management concept stating, “We believe in the value of design and implement it in our corporate management.” The color variations of the company’s products (olive green, navy blue, charcoal gray, etc.) show a different trend from the typical white and black-centric offerings common in the peripheral device sector.
Safety and Certifications
DIGIFORCE products sold in Japan have obtained the following safety certifications:
- PSE Mark: Certification based on the Electrical Appliance and Material Safety Act. Obtained for iPhone compatible batteries and power tool compatible battery products.
- Various Protection Functions: Equipped with overcharge protection, over-discharge protection, overcurrent protection, overheat protection, and short-circuit protection.
