Why choose MELCON PD Charger PCBA?

• Universal compatibility: Works with almost every modern mobile phone, tablet, neckband, smartwatch and many laptops that charge via USB-C.

• Multiple port choices: Single-port and multi-port options in USB-C, USB-A, or both (A+C) let you charge legacy gear and the newest devices together.

• Wide power range: Pick the right wattage for your needs — 20W for phones and wearables, 45W or 65W for tablets and ultrabooks, 105W for heavier laptops and fast multi-device setups.

• Smart power delivery: USB Power Delivery (PD) and adaptive charging protocols ensure each device receives the ideal voltage and current.

• Compact, travel-friendly design: Small footprint and foldable prongs for easy carry without sacrificing cooling or durability.

Key features (at a glance)

• Power options: 20W, 45W, 65W, 105W

• Port configurations: USB-C only, USB-A only, USB-A + USB-C

• Fast charging protocols supported: USB PD (various profiles), QC (Quick Charge) compatibility on USB-A ports, and adaptive output for wearables

• Intelligent multi-port distribution: When multiple devices are connected, the charger balances wattage dynamically to maximize overall charging speed and safety

• Thermal management: Built-in temperature sensors and smart throttling prevent overheating

• Safety protections: OVP (over-voltage), OCP (over-current), SCP (short circuit), OTP (over-temperature), and surge protection

• High efficiency: Low standby loss and high conversion efficiency to reduce heat and energy waste

• Durable build: Reinforced housing and premium connectors for long life

How the wattage choices match real-world use

• 20W — Ideal for smartphones, earbuds, neckbands and smartwatches. Great for daily carry and fast top-ups.

• 45W — Excellent for tablets and bigger phones (faster charging), or for charging a phone and a tablet simultaneously.

• 65W — Suitable for larger tablets, ultraportable laptops and heavier multi-device users. Often the sweet spot for users who want laptop capability without a bulky brick.

• 105W — For power-hungry laptops, rapid multi-device charging or users who want to charge a laptop + phone + accessory at full speed simultaneously.

Typical functions and how MELCON optimizes them

• Single-device fast charge: When one device is connected, MELCON routes full PD output to that device to achieve maximum possible speed (within device limits).

• Multi-device balancing: When multiple devices are connected, the charger intelligently splits available power so phones still get rapid charging while laptops or tablets get the remaining wattage.

• Device negotiation: Uses USB-C PD negotiation to match voltage (5V / 9V / 15V / 20V or higher where supported) and current to device capabilities.

• Wearable mode: For low-power accessories like smartwatches and neckbands, MELCON drops to lower voltages/currents and applies soft start to protect small batteries.

• Cable awareness: Compatible with high-quality PD cables to achieve rated outputs; includes safeguards when lower-grade cables are detected.

Compatibility checklist (what it charges)

• Modern Android phones (Samsung, OnePlus, Google Pixel, etc.)

• iPhone models that support PD fast charge (with USB-C to Lightning)

• Tablets (iPad, Android tablets)

• USB-C neckbands and earbuds charging cases

• Smartwatches that accept USB charging docks/cables

• Laptops that accept USB-C PD input (ultrabooks, many MacBooks, Chromebooks, etc.) — check device’s max PD input to pick 65W or 105W if needed

Practical scenarios

• Daily commuter: 45W A+C variant — charge your laptop on the go, while your phone and earbuds top up.

• Travel minimalist: 65W USB-C single port — one brick to replace laptop charger + phone charger.

• Family charging station: 105W multi-port A+C — charge multiple phones, a tablet and a laptop simultaneously at safe speeds.

• Pocketable backup: 20W compact USB-C — fast phone top-ups and wearable charging.

Safety & longevity tips

• Use high-quality USB-C PD cables (especially for 65W+ charging).

• Keep vents clear; avoid charging in tightly sealed covers while under heavy load.

• Don’t exceed your device’s manufacturer-recommended charging specs — the charger negotiates safely, but matching wattage prevents unnecessary heat.

• For long battery life: avoid leaving devices at 100% plugged in for prolonged periods and avoid extreme temperatures.
