What is the MAXCO MP39 Legend 2?

The MAXCO MP39 Legend 2 is a dual-interface portable charger that merges MagSafe-compatible magnetic wireless charging with USB-C Power Delivery in a single 10000mAh unit. Its N52-grade magnet array creates a secure 360° hold on MagSafe iPhones (13 through 15 Pro Max) and MagSafe-enabled Android devices, while the USB-C port negotiates up to 20W PD 3.0 for phones, tablets, and small laptops. The high-density polymer cell maintains ≥80% capacity after 1000 charge cycles per manufacturer lab data.

Key Features

• 15W magnetic wireless output — charges iPhone 15 Pro Max from 0-50% in approximately 30 minutes when aligned
• 20W USB-C PD 3.0 wired output — supports 5V/3A, 9V/2.22A, 12V/1.67A voltage profiles for broad device compatibility
• Pass-through charging — replenishes the power bank via USB-C while simultaneously powering a connected device
• Multi-stage safety suite — over-voltage, over-current, short-circuit, and foreign-object detection (FOD) for wireless mode
• LED capacity indicator — four white LEDs show 25% increments; long-press activates low-current mode for earbuds and wearables

Power for Every Situation

Whether you're commuting or traveling internationally, the MAXCO MP39 Legend 2 provides 1-2 full smartphone charges from its 10000mAh buffer. The magnetic alignment system ensures a secure 360° connection without the need for precise placement. Unlike generic power banks, this model uses premium polymer cells for extended capacity retention and enhanced lifespan.

Daily commute

Snap the power bank onto an iPhone 14 Pro during a 45-minute train ride; the 15W magnetic charge adds roughly 35% battery while you read or listen to podcasts. The slim 43mm thickness lets the paired devices slide into a jacket pocket without bulging.

International travel

At 37Wh, the unit falls well under the 100Wh airline carry-on limit. Use the 20W PD port to top up a Nintendo Switch (approx. 18W draw) during a layover while your phone charges wirelessly on the magnet. The included mesh pouch protects the finish from keys and cables.

Remote work sessions

Connect a USB-C iPad Air (2022) via PD for 20W charging while an Android MagSafe phone draws 15W wirelessly. Combined 35W output sustains both devices through a 4-hour video call without needing a wall outlet.

Why Choose MAXCO Over Competitors?

Compared to similar 10000mAh power banks in the $35-$45 range, the MAXCO MP39 Legend 2 offers superior dual-charging versatility. While many competitors either offer magnetic charging or PD wired ports separately, this unit integrates both technologies. The smart temperature control system surpasses basic overheating protection by regulating energy output dynamically based on ambient conditions.

Versus magnetic-only banks

Most magnetic-only models cap at 7.5W wireless and lack a PD port, forcing a second charger for iPads or laptops. The MP39 Legend 2’s 15W wireless matches Apple’s MagSafe charger speed, and the 20W PD port handles larger devices.

Versus PD-only banks

Traditional PD power banks require cables for every device. The magnetic interface eliminates cable clutter for iPhone users and adds Qi compatibility for Galaxy S23/S24, Pixel 8/9, and other Qi-enabled phones (at 5W–10W depending on handset).

---

Certified Safety & Efficiency

All charging parameters adhere to USB-IF and Qi standards. The power bank's polymer battery cells have passed 1000+ charge cycles in lab testing ( per manufacturer data ), with voltage stability maintained within ±5% during 10-hour wireless charging cycles. For travelers, the compact 133g design and included travel pouch make it ideal for handbags and backpacks.

Thermal management detail

An NTC thermistor samples cell temperature every 5 seconds. If the surface exceeds 42°C, the MCU reduces wireless output in 2.5W steps; above 45°C it suspends wireless entirely while maintaining PD output at reduced wattage. This prevents the throttle-recover cycles that degrade cell health in simpler designs.

Foreign object detection

The wireless coil runs a 100kHz resonance check before each charge session. Metal cards, coins, or thick cases (>3mm) trigger FOD and halt power transfer, protecting both the power bank and the object from inductive heating.

Dual Charging Use Cases

1. Commute charging: Top up your iPhone 14 via magnetic charge while your Android phone receives 20W PD power
2. Travel emergency: Use wired 20W PD to quickly charge a depleted laptop (output: 18W USB-C)
3. Dual device charging: Power a tablet and smartphone simultaneously through PD and wireless ports

Additional real-world scenarios

• Coffee shop workflow: MacBook Air M2 (accepts 20W PD for trickle charge) + iPhone 15 Pro wireless = zero cable mess on a small table
• Outdoor photography: Sony A7C (USB-C PD) + iPhone 14 Pro Max wireless during a 6-hour shoot; 10000mAh covers both with ~15% reserve
• Family road trip: Kids’ Nintendo Switch (PD) + parent’s Android (wireless) from a single bank mounted on the seatback

---

Who It’s For

• iPhone 13/14/15 series owners wanting cable-free MagSpeed charging on the move
• Android users with MagSafe cases or built-in magnetic arrays (e.g., Xiaomi 14, HONOR Magic series)
• Frequent flyers needing a sub-100Wh bank with both wireless and 20W PD for tablets/laptops
• Minimalist commuters who prefer a single 133g device over separate charger + cable kits

---

What’s Included

• MAXCO MP39 Legend 2 power bank
• USB-C to USB-C cable (0.5m, 5A rated, supports 20V/5A for future-proofing)
• Mesh travel pouch with hook-and-loop closure
• Quick-start guide (multilingual) and warranty card (12-month limited)

---

Buying Guidance

Choose the MP39 Legend 2 if you carry both an iPhone (13 or newer) and a USB-C device (iPad, Switch, Android phone, ultraportable laptop) and want one bank that handles both without cables for the iPhone. If you exclusively use Lightning or Micro-USB devices, a cheaper PD-only bank may suffice. For users needing ≥3 phone charges per cycle, consider a 20000mAh model; the 10000mAh sweet spot balances airline compliance, pocketability, and 1–2 full charges for most flagship phones.

---

Care & Maintenance

• Store at 50–70% charge if unused for >30 days; recharge to 50% every 3 months to prevent deep-discharge lockout
• Clean magnetic face with a dry microfiber cloth; avoid liquids near the coil perimeter
• Use only USB-IF certified cables for PD input/output to maintain voltage negotiation integrity
• Do not expose to direct sunlight >35°C for extended periods (e.g., dashboard in summer)
