The YILANS JM4 Pro is a 50000mAh portable power bank aimed at multi-device travelers. It offers 22.5W USB-C PD fast charging (claims 65% iPhone charge in 30 min), 6 output + 2 input ports, and 4 built-in cables (USB-C, Lightning, Micro-USB, USB-A), eliminating carry-over cable clutter. At 503g (1.14 lb) and modest dimensions (5.61" × 2.88" × 1.14"), it's reasonably portable for its capacity.
Strengths: Built-in multi-cable design, large capacity per dollar (~$30 at Prime discount), real-time LED display, claimed overvoltage/overcurrent protection, 3-year warranty, pass-through charging support.
Trade-offs: YILANS is a lesser-known Chinese brand with limited community endorsement; no third-party test data on actual mAh delivery or sustained output under load. The 22.5W rating appears to apply only to USB-C PD—USB-A ports likely charge slower. At 503g, it's heavier than premium 50000mAh rivals (Anker, Baseus). Charging reviews mention uneven ramp speeds and slower simultaneous multi-device charging. Real-world capacity and durability reports remain sparse.
