Magnetic Charger Port 1 Pin
Dongguan Xinteng Electronics Co., Ltd. is one of the most reliable manufacturers and suppliers of magnetic charger port 1 pin in China, featured by quality products and good service. Welcome to wholesale bulk durable magnetic charger port 1 pin in stock here from our factory. Also, customized service and OEM&ODM service are available.
Product Introduction
Magnetic Charger Port 1 Pin(RM-1087) is a single-pin magnetic charging port. The whole thing is 8.0 mm in diameter . One pin in the center, insulating plastic, a ring magnet around it, and a brass shell on the outside. Snap it near the mating side and the magnet pulls it the rest of the way. No alignment needed, no plugging in the dark.
We built this for devices where space is tight and the user doesn't want to think about orientation. Smart rings, pet trackers, small medical patches, handheld scanners - anything where a USB-C port would eat too much board space or stick out too far.
Current rating is 3A at 12V. That's enough for fast charging most small batteries. If you need more than 3A, we have a 2-pin version that splits the current, or we can bump the pin diameter on a custom job.
Standard units ship in 2–7 days. Custom plating or housing color adds about a week.

Polarity & Wiring
By default, the center pogo pin is positive and the outer brass shell is negative. The magnet itself doesn't carry current - it's insulated from the shell by a plastic ring. If your circuit board layout requires the connection of signal lines, please inform us during the consultation. We will provide you with a solution that can accommodate both power lines and signal lines.

Is This the Right Part for You? Quick Check
| Your Situation | Verdict |
|---|---|
| Device outer diameter under 15 mm | ✅ RM-1087 fits |
| Charging only (no data) | ✅ Perfect match |
| Charging current 1A–3A | ✅ Handles it |
| User wears device (patch, pendant) | ✅ No fumbling with orientation |
| Needs IPX4 splash resistance | ⚠️ Custom seal available; standard is not waterproof |
| Needs IPX7 submersion | ❌ You can choose connectors of other waterproof models. |
| Operating temp regularly above 85°C | ❌ N52 magnet degrades; switch to SmCo or go non-magnetic |
Innovative Applications of Magnetic Charger Port
- Fast Charging Devices
For example, using magnetic connectors between chargers and batteries has become a trend. This 8.0mm diameter magnetic connector provides DC 12V voltage and a maximum current of 3A. The magnetic design not only allows for quick docking but also avoids the wear and tear of traditional plugs during insertion and removal, extending the device's lifespan.
- Smart Home Devices
More and more devices are using magnetic connection solutions. For example, various devices such as smart speakers, smart lights, and home controllers require frequent power connections. Using magnetic connectors makes the connection process simpler and more efficient. Users simply bring the connector close to the device port, and the magnet quickly locks it in place, avoiding the complicated insertion and removal operations of traditional plugs and improving the user experience.
- Wireless Audio Devices
Magnetic connectors also bring great convenience to audio devices such as wireless speakers and story machines. For example, with wireless speakers, magnetic connectors not only simplify the charging process but also ensure accurate docking every time, avoiding the problem of unstable charging contacts. This magnetic charging connector is ideal for use in small devices, saving space and improving charging speed and device stability.
- Modular Design of Smart Hardware Products
Many electronic products are increasingly adopting modular designs, and magnetic connectors facilitate modular power connections and data transmission in these products. This design significantly reduces the difficulty of device maintenance, allowing users to easily replace or upgrade modules without worrying about loose or worn connections.
Customization Process
- Send Requirements
Send your PCB layout, current needs, and housing constraints. or provide us with physical samples for us to measure.
- Proposal
2D drawing and quotation back in 1 business days.
- Sample Approval
Standard samples can be applied for for free on a single basis. The shipping cost is borne by you and it usually takes 3 to 7 days. Customized samples (with different electroplating, shell colors, and polarity reversal) will take 7 to 10 days.
- Tooling / Pilot Run
After sample approval, standard models need no new mold. Custom housing shapes need tooling; budget 7–15 days and USD 1,500–3,800.
- Mass Production & Delivery
Standard lead time 15–20 days. Rush orders can be discussed.
