When the Grid Goes Silent, What Do You Hear?
Most people discover their radio only after they need it — during a blackout, in a storm, at a campsite with no signal, or in the aftermath of something that took the cellular network down with everything else. The Signal Keeper is designed for that moment, but built to be worth using every day in between. It is a DAB+/FM radio with digital station tuning, a Bluetooth 5.0 speaker for your phone's playlist, a solar panel that feeds the battery while you read outside, a hand crank that turns muscle into minutes of broadcast, and an LED flashlight that switches to SOS mode when flashing red and blue is the difference between being found and being passed by.
The 2000mAh rechargeable battery is the foundation — charged via USB-C in three hours, maintained by the top-panel monocrystalline solar cell, and backed up by a dynamo crank that converts one minute of effort into ten minutes of listening. This is not a single-source device that becomes a paperweight when its one charging method fails. It is a multi-path energy architecture designed for the reality that emergencies do not schedule themselves around your battery percentage.
DAB+ digital radio delivers CD-quality audio with zero static and full station metadata on the 2.4-inch LCD. FM covers everywhere DAB+ hasn't reached yet. Bluetooth 5.0 connects to your phone for podcasts, Spotify, and internet radio — turning the Signal Keeper into your daily-use portable speaker. USB and microSD playback handles offline audio libraries. And the IPX5 water resistance means rain, splashes, and damp camping gear do not end the conversation. This is not a radio you keep in an emergency kit and forget. It is a radio you use every day, and when the day comes that you need its full capabilities, it is already in your hands.
Information is the first supply line to break in any emergency. A radio that works is a radio you already know how to use.
Key Features
- ✦ DAB+ / DAB / FM Digital Radio — Crystal-clear digital reception with station name, track info, and signal strength displayed on the 2.4-inch LCD. FM for regions without DAB+ coverage.
- ✦ Bluetooth 5.0 Speaker — Stream music, podcasts, and internet radio from any smartphone. A2DP profile ensures high-quality audio. 10-meter range.
- ✦ Triple Power Architecture — 2000mAh lithium battery (USB-C recharge, 3 hours to full) + integrated solar panel (maintains charge during daytime use) + hand crank dynamo (1 min cranking = ~10 min radio). Redundant power pathways mean you are never truly out of options.
- ✦ USB & microSD Playback — Insert a USB drive or microSD card (up to 32GB, FAT32) with MP3/WMA files for offline music, audiobooks, or language-learning content. Navigate folders with the track buttons.
- ✦ 3W Full-Range Speaker — Custom-tuned driver with passive bass radiator for surprisingly rich audio from a compact enclosure. Loud enough to fill a campsite or workshop.
- ✦ 1W LED Flashlight with SOS Mode — Integrated flashlight operates independently of the radio. SOS mode flashes the international distress signal (three short, three long, three short) automatically.
- ✦ IPX5 Water-Resistant — Withstands heavy rain, splashes, and wet conditions. Rubber-sealed port covers protect USB/SD/card slots. Not submersible — keep it afloat, not underwater.

Who This Is For
The Signal Keeper serves anyone who values information resilience. Campers and overlanders use it as their daily campsite speaker and nightly radio. Emergency preparedness households keep one in their go-bag alongside water and first-aid supplies. Boaters and kayakers rely on the IPX5 rating and hand crank when electronics are exposed to the elements. European and Australian residents get the full DAB+ experience with dozens of crystal-clear digital stations. US users treat it as an excellent portable Bluetooth speaker with a backup FM radio and the most reliable flashlight they'll ever forget to charge. And anyone who has ever been caught in a power outage with a dead phone and no way to know what's happening outside their dark living room — this device was designed for you, even if you don't know it yet.
Frequently Asked Questions
Q: What is DAB+ and why does it matter?
A: DAB+ (Digital Audio Broadcasting Plus) is the modern digital radio standard used across Europe, Australia, and parts of Asia. Unlike traditional FM, DAB+ delivers CD-quality audio with zero static or interference, displays station names and track information on screen, and offers a much wider station selection — many cities have 30-50+ DAB+ stations versus 10-15 FM stations. If you live in or travel to a DAB+ broadcast region, this radio unlocks a dramatically better listening experience.
Q: Can the solar panel fully charge the battery?
A: In full, direct sunlight, the integrated 200mA solar panel will trickle-charge the 2000mAh battery over 8-10 hours. In practice, the solar panel is best understood as a range extender rather than a primary charger — it maintains battery level during daytime outdoor use and provides emergency top-up capability when grid power is unavailable. For full recharges, USB-C charging (3 hours to full) is the primary method.
Q: How reliable is the hand crank in an emergency?
A: The hand crank dynamo is a genuine emergency backup, not a gimmick. Approximately 1 minute of steady cranking at 120-150 RPM generates enough charge for 8-12 minutes of radio playback or 15-20 minutes of flashlight use. The internal supercapacitor smooths the hand-crank output into usable DC — you cannot over-crank or damage the circuit. For emergency preparedness kits, this is the feature that makes the Signal Keeper a communication lifeline when batteries are dead and the sun is down.
Q: Does DAB+ work in the United States?
A: The United States uses HD Radio (IBOC) rather than DAB+ for digital broadcasting — the DAB+ tuner will not receive digital stations in the US. However, the FM tuner works globally, and the Bluetooth 5.0 connection turns the radio into a portable speaker for any smartphone streaming app (Spotify, podcasts, internet radio, audiobooks). For US users, this is primarily a superb portable Bluetooth speaker with an excellent FM radio, emergency flashlight, and multi-source charging.
Q: Can I play music from a USB drive or microSD card?
A: Yes. Insert a USB flash drive or microSD card (FAT32 formatted, up to 32GB) loaded with MP3 or WMA files, and the radio automatically detects and plays them. Folder navigation uses the previous/next track buttons to cycle through directories. This is particularly useful for curated offline music collections, language-learning audio files, or audiobooks when you want a dedicated playback device that isn't your phone.
Q: How well does the IPX5 water resistance hold up?
A: IPX5 means the radio withstands water jets from any direction — equivalent to heavy rain or a shower spray. It will survive a rainy campsite, a splash from a kayak paddle, or being left on a damp picnic table. It is NOT submersible (do not drop it in a lake) and the USB/SD card ports should have their rubber covers sealed when exposed to water. The speaker grille and control buttons are fully sealed against water ingress.
