Elecrow ThinkNode M4 Power Bank LoRa Device with Meshtastic is a multifunction Meshtastic communication device that combines a power bank, LoRa node, GPS tracker, and emergency utility tool in one portable unit. Based on official Elecrow materials, the ThinkNode M4 is built around the Nordic nRF52840 and Semtech LR1110, and is designed specifically for Meshtastic style off-grid communication, location sharing, and private mesh networking. What makes this product stand out is that it does more than act as a simple LoRa node. The 7000mAh battery, 22.5W wired power output, 15W wireless charging, multi-GNSS positioning, Bluetooth phone configuration, environmental sensors, and SOS emergency light make it especially suitable for outdoor carry, emergency preparedness, disaster response, remote travel, and tracker-style deployment. If you want a Meshtastic device that also works as a practical power and positioning tool, this is the core direction to optimize around. Features Meshtastic ready LoRa communication device for off-grid messaging and decentralized private networks Nordic nRF52840 + Semtech LR1110 hardware platform for long-range low-power communication Built-in GPS with support for GPS, BeiDou, GLONASS, and QZSS for positioning and location sharing Power bank functionality with 7000mAh capacity, 22.5W wired output, and 15W wireless charging Bluetooth 5.4 support for phone-based configuration and local setup Emergency utility design with LED light modes including Normal, Strong, and SOS Flash Built-in sensors including temperature, humidity, and 6-axis gyroscope data collection Compact all-in-one device for hiking, rescue, field work, remote travel, and tracker deployment Specifications Parameter Details Brand Elecrow Product ThinkNode M4 Power Bank LoRa Device Primary Ecosystem Meshtastic CPU / SoC Nordic nRF52840-QIAA System Memory 256 KB RAM Storage 3 MB Flash including 2MB external Flash LoRa Transceiver Semtech LR1110 Firmware Compatibility Meshtastic firmware, optional LoRa Tracker function Bluetooth BLE and Bluetooth 5.4 LoRa Frequency US 915MHz / EU 868MHz, internal antenna GPS Positioning GPS, BeiDou, GLONASS, QZSS, ceramic antenna Battery Type 18650 Lithium-ion Nominal Capacity 7000mAh Total Power 3.6V / 25.2Wh Rated Capacity 3800mAh at 5V / 3A Wired Output Power Up to 22.5W Wireless Charging 5W, 7.5W, 10W, 15W max Full Charging Time Approx. 3 to 4 hours Emergency Light LED, Normal / Strong / SOS Flash Sensors Temperature and humidity sensor, 6-axis gyroscope Power Consumption Static 45mA, sleep 55uA, TX max 175mA, RX max 54mA Dimensions and Weight 87.3 x 67.7 x 28mm, 190g Enclosure ABS fireproof plastic + PC + TPE Applications Meshtastic off-grid communication and location sharing Outdoor tracking for hiking, camping, overlanding, and remote travel Emergency preparedness and disaster response where cellular coverage is unavailable Private mesh networking for groups, teams, or local field coordination Portable backup power for phones and small devices during field use LoRa tracker style deployments where power, positioning, and messaging need to stay together in one device Packing List ThinkNode M4 Power Bank x1 Charging Cable x1 USB to USB-C Converter x1 User Manual x1 Other Content The most important point for this product is that it combines communication and utility in one enclosure. A normal Meshtastic node may only provide messaging, but the ThinkNode M4 also adds battery backup, wireless charging, GPS positioning, environmental sensing, and emergency lighting. That makes it more practical for users who want an everyday-carry or field-ready Meshtastic device instead of a simple development board. Elecrow's official material also makes the outdoor and emergency use case very clear. This is a product that fits hiking, disaster relief, private team communication, and mobile tracking much better than an indoor bench-only LoRa module. If your goal is a Meshtastic tracker, a power bank, and a rugged field communication tool in one device, this is the strongest angle to emphasize. If you are building or configuring a Meshtastic setup around the ThinkNode M4, you can also refer to OpenELAB's own Meshtastic overview page and the related Meshtastic device configuration guide for role settings, rebroadcast behavior, tracker setup, and other deployment details.Resources Elecrow Official Wiki ThinkNode M4 User Manual PDF Meshtastic Official Website OpenELAB Meshtastic Overview OpenELAB Meshtastic Device Configuration Guide FAQ Is this product mainly intended for Meshtastic?
