| Cordless chopper (150W BLDC) | $12-15 | 2,000 |
|---|
The higher MOQ for cordless products (2,000 vs 1,000 for corded) is driven by battery cell minimum order quantities from Samsung and LG distributors.

FAQ
Q: How long does a cordless mixer battery last?
A: 15-20 minutes of continuous mixing at medium speed. The battery is rated for 500+ charge cycles to 80% capacity. Gainer uses Samsung INR18650-25R or LG INR18650-M26 cells.
Q: Can I use the same battery across different cordless products?
A: Yes, if the products share the same battery platform. Gainer’s cordless hand blender, hand mixer, and chopper all use the same 18V removable battery pack.
Q: What certifications does Gainer’s cordless platform carry?
A: CE, GS, CB, RoHS, LFGB, ETL, and FDA. The battery pack is certified to IEC 62133 and UN 38.3. The charger is certified to EN 60335-2-29.
Q: What’s the MOQ for cordless mixer OEM?
A: 2,000 units per model. The higher MOQ is due to battery cell minimums. Payment: 30% T/T, 70% before shipment.
Q: Does Gainer offer the cordless mixer with a fixed battery?
A: Both options are available. Removable battery (slide-lock) is the recommended design for product longevity and accessory sales. Fixed battery is slightly cheaper but cannot be replaced by the user.

Battery Safety: IEC 62133 and UN 38.3
The battery pack in a cordless mixer is a lithium-ion energy storage device. It must pass two critical safety standards:
IEC 62133 (Safety of Secondary Lithium Cells and Batteries)
This standard is required for CE marking. Tests include:
– Short circuit: The fully charged battery is short-circuited. Must not catch fire or explode within 24 hours.
– Overcharge: The battery is charged at 2× the recommended current. Must not catch fire or explode.
– Forced discharge: A single cell is discharged to 0V. Must not catch fire or explode.
– Crush: The battery is crushed with a 13kN force. Must not catch fire or explode.
– Impact: A 9.1kg weight is dropped on the battery from 610mm. Must not catch fire or explode.
– Thermal abuse: The battery is heated to 130°C and held for 10 minutes. Must not catch fire or explode.
Gainer’s battery pack has passed all IEC 62133 tests at TÜV Rheinland. The BMS (Battery Management System) is the safety net — it prevents overcharge, over-discharge, and short circuit at the electronic level, before the cell reaches a dangerous condition.
UN 38.3 (Transport of Dangerous Goods)
This standard is required for shipping lithium batteries by air or sea. Tests include:
– Altitude simulation: Simulates air transport at 15,000m (11.6 kPa)
– Thermal test: -40°C to +75°C cycling
– Vibration: Sine sweep 7-200 Hz
– Shock: 150g peak acceleration
Gainer’s battery pack carries UN 38.3 test reports. The factory provides the MSDS (Material Safety Data Sheet) and UN 38.3 test summary with every battery shipment.
Motor Efficiency and Battery Runtime
The BLDC motor’s efficiency directly determines battery runtime. A 5% efficiency improvement means 5% longer runtime from the same battery. Gainer’s motor optimization:
– Lamination thickness: 0.35mm silicon steel vs the industry standard 0.5mm. Thinner laminations reduce eddy current losses by 40% (eddy current loss is proportional to the square of lamination thickness).
– Magnet grade: N35SH (150°C rated) vs standard N35 (80°C). The SH grade maintains magnetic flux at operating temperature, preventing performance degradation during extended use.
– Air gap: 0.35mm between rotor and stator. Tighter gap increases magnetic flux density. Requires precision machining of bearing seats and rotor shaft.
– Winding fill factor: 75% (ratio of copper area to slot area). Higher fill factor reduces resistance and I²R losses. For more, read Stand Mixer Factory China OEM.
These optimizations add $0.80-1.20 to the motor cost but improve runtime by 15-20% compared to a standard BLDC motor. For a cordless product, runtime is the number one user complaint — investing in motor efficiency reduces returns.
Charger Design and Safety
The charger is a separate appliance and must be certified independently:
– Input: 100-240V AC, 50/60Hz (universal voltage)
– Output: 21V DC, 2A (CC/CV charging profile)
– Safety: EN 60335-2-29 (battery chargers), double-insulated (Class II)
– Plug: EU (CEE 7/16), UK (BS 1363), US (NEMA 1-15), AU (AS/NZS 3112) — interchangeable
– Protection: Over-current, over-voltage, short-circuit, reverse polarity
The charger uses a CC/CV (Constant Current / Constant Voltage) charging profile. During the CC phase, the charger delivers 2A until the battery reaches 21V. During the CV phase, the charger holds 21V and the current gradually decreases. When the current drops below 100mA, charging is complete. This profile maximizes battery life compared to simple constant-voltage charging. This connects to our guide on Best Kitchen Appliance OEM Manufacturers.
The Removable Battery Ecosystem
Gainer’s removable battery pack is designed as a platform — not a single-product component. The same battery works across:
– Cordless hand blender
– Cordless hand mixer
– Cordless chopper
– Portable blender Related: Cordless Hand Blender OEM.
This cross-product compatibility creates a brand ecosystem. A customer who buys the hand blender and then buys the hand mixer doesn’t need a second charger or battery system. The brand can sell spare batteries as accessories ($15-25 retail), generating additional revenue. The platform approach also reduces the brand’s inventory complexity — one battery SKU supports multiple products. See also: Food Mixer OEM Manufacturer.
