In the mobile accessory business, "Model-Specific" inventory is a gamble.
You order 500 battery cases for the iPhone 14 Pro Max. Three months later, the iPhone 15 launches with a slightly different camera bump or charging port. Suddenly, your remaining stock becomes obsolete "dead inventory" that you have to sell at a loss.
As a factory supplier, Doolike has seen this cycle repeat for years. That is why we engineered the Model X12 Universal Telescopic Battery Case.
It’s not just a charger; it’s an inventory safety net for wholesalers and retailers.
1. The Problem: The "One-to-One" Restriction
Traditional battery cases are molded precisely for one specific phone model.
The Risk: If you stock cases for Samsung S23 Ultra, they won't fit the S24 Ultra.
The Cost: Retailers are forced to carry dozens of SKUs (Stock Keeping Units) just to cover the popular models. This ties up cash flow and shelf space.
2. The Solution: The X12 "One-to-Many" Design
| Feature | Traditional Battery Case | Doolike X12 Universal Case |
| Model Compatibility | 1 Case = 1 Phone Model Only | 1 Case = 90% of Phones (155-169mm) |
| Inventory Risk | High (Dead stock if phone discontinued) | Zero (Sell to anyone, anytime) |
| Case Compatibility | Must remove phone case | Clip-on (Works with slim cases) |
| Interface | Fixed | Choice of Lightning or Type-C |
| Cost Efficiency | Buy 20 SKUs to cover market | Buy 1 SKU to cover market |
The Doolike X12 changes the game with its Retractable Back Clip Design. Instead of a fixed mold, it uses a durable spring-loaded mechanism that extends vertically.
Universal Fit: It fits ANY smartphone with a height between 155mm and 169mm.
Market Coverage: This single size covers the most popular power-user devices, including:
iPhone 12/13/14/15/16 (Plus & Pro Max models)
Samsung Galaxy S22/S23/S24 (Ultra & Plus models)
Huawei Mate & P Series (Pro models)
The Benefit: You only need to stock one product to serve customers with 20 different phone models.
3. Future-Proofing with Dual Interfaces
The mobile world is transitioning from Lightning to USB-C. The X12 prepares you for both. We offer two versions of the built-in connector:
Lightning Version: For the massive existing user base of iPhone 6 through 14.
Type-C Version: For the new iPhone 15/16 series and the entire Android ecosystem.
Pro Tip for Retailers: By stocking a 50/50 split of these two interfaces, you ensure that every customer walking into your shop can find a compatible battery pack, regardless of their device age.
4. User Experience: Case-Friendly & Portable
Unlike bulky traditional battery cases that require users to peel off their protective cases, the X12 is designed as a "Clip-On" Power Bank.
Case-Friendly: Customers can keep their favorite thin protective case on. The X12 simply clips onto the back.
Emergency Power: With 10W output, it provides that critical extra 50-80% battery life to get through a busy day of travel or gaming.
Hidden Stand: It even includes a foldable kickstand for watching videos while charging.
Conclusion: Simplify Your SKU List
Stop gambling on which phone model will be popular next month. Start stocking the X12 Universal Battery Case. It allows you to reduce your SKU count, minimize inventory risk, and never say "Sorry, we don't have a case for that model" again.
