I remember a particularly nasty ice storm a few years back. The power went out, and with it, the internet, the TV, and our connection to the outside world. My smartphone battery was draining fast, and I was rationing it just to get occasional updates. The silence was unnerving. We felt isolated, unsure of when power would be restored or if conditions were worsening. It was in that quiet, powerless state that I truly understood the profound need for a reliable, old-school piece of technology: a good radio. Not just any radio, but one that didn’t depend on the wall outlet, could pick up emergency weather alerts, and maybe even play some music to keep spirits up. This search for a dependable companion for both emergencies and casual listening led us to rigorously test the Jazmm Portable AM FM Shortwave Radio Rechargeable.

What to Consider Before Buying a Portable Shortwave Radio
A portable shortwave radio is more than just an item; it’s a key solution for staying informed, entertained, and safe when modern infrastructure fails. It’s a bridge to global news, a source of local updates during a storm, and a personal media player for off-grid adventures. The main benefits are independence from the internet and the power grid, access to a wide spectrum of broadcasts including vital NOAA weather alerts, and the simple, tactile pleasure of tuning a dial and discovering something new. In an increasingly digital world, having an analog backup is not just nostalgic; it’s a fundamental part of being prepared.
The ideal customer for this type of product is someone who values preparedness and versatility. This includes homeowners building an emergency kit, outdoor enthusiasts like campers and hikers, and radio hobbyists who enjoy exploring the airwaves. It’s also perfect for those in rural areas with spotty cell service or anyone who simply wants a dedicated device for listening to music or news without draining their phone battery. Conversely, this might not be the right fit for audiophiles demanding concert-hall fidelity or for someone who exclusively uses streaming services and has no interest in terrestrial radio. If you need a pocket-sized device for travel, a more compact model might be better, whereas a serious shortwave hobbyist might seek out a radio with advanced features like Single Sideband (SSB).
Before investing, consider these crucial points in detail:
- Dimensions & Space: Portability is key, but it’s a spectrum. The Jazmm radio measures 9.96″ x 3.8″ x 7.87″, making it a substantial tabletop unit rather than a pocket radio. Consider where you’ll store it in your home or how much space it will occupy in an emergency go-bag or on a campsite picnic table. Its size allows for a large speaker and clear controls, which is a worthy trade-off for its larger footprint.
- Capacity/Performance: This is the heart of the radio. Look at battery life (the Jazmm boasts a 4000mAh rechargeable battery for up to 18 hours), charging options (USB-C), and backup power (support for 4 D-cells is a huge plus). On the performance side, a digital tuner, like the one found here, offers more precise station-locking than an analog dial. Crucially, verify the bands it supports—AM, FM, Shortwave (SW), and Weather Band (WB) with NOAA alerts are the gold standard for a versatile emergency radio.
- Materials & Durability: Most portable radios, including this one, feature a plastic enclosure to keep weight down. While not built for extreme ruggedness like a military-grade device, the plastic should feel solid and not flimsy. The design, with its integrated fold-down handle, speaks to its intended use for portability around the house, garage, or campsite rather than hardcore wilderness trekking.
- Ease of Use & Maintenance: In a stressful situation, you don’t want to be fumbling with complex controls. We look for large, clearly labeled buttons, an easy-to-read backlit display, and intuitive functions. One user praised the Jazmm’s large display as a great help for aging eyes. For maintenance, a simple wipe-down is all that’s needed, and the dual power system means you only need to ensure the internal battery is charged or have a set of D-cells on hand.
While the Jazmm Portable AM FM Shortwave Radio Rechargeable is an excellent choice, it’s always wise to see how it stacks up against the competition. For a broader look at all the top models, we highly recommend checking out our complete, in-depth guide:

First Impressions: A Modern Take on a Classic Device
Unboxing the Jazmm Portable AM FM Shortwave Radio Rechargeable, the first thing we noticed was its size and “modern” blue styling. It feels substantial without being overly heavy, weighing in at about 800 grams. The large, front-facing speaker grille dominates the design, promising a powerful sound. The controls are logically laid out, with a large tuning knob, a dedicated volume knob, and clearly marked buttons for band selection, presets, and MP3 player functions. The star of the show is the large, clear LCD screen, which is brightly backlit, confirming a user’s observation that it’s a huge benefit for anyone with less-than-perfect vision. The fold-down handle feels sturdy and clicks satisfyingly into place, making the unit easy to carry from room to room. In the box, we found the radio and a USB-C charging cable. As one user correctly pointed out, there’s no 5V power adapter included, but in an age where these are ubiquitous for charging phones, we didn’t find this to be a significant drawback. It feels like a thoughtful blend of classic radio functionality with modern conveniences like a digital display and media playback, making it immediately approachable. You can see its full feature set and clean design here.

Performance Deep Dive: Putting the Jazmm Radio to the Test
A radio’s worth is measured in its ability to perform when you need it most. We spent weeks with the Jazmm Portable AM FM Shortwave Radio Rechargeable, using it as a kitchen companion, a workshop entertainer, and an emergency preparedness drill centerpiece. We tested its battery, fiddled with every band, and loaded it with music to see if it lives up to its multi-function promise. Here’s our in-depth analysis of its core features.
Power and Endurance: The 4000mAh Heart and its D-Cell Backup
The single most critical feature of any emergency radio is its power source. The Jazmm radio addresses this with an excellent dual-power strategy. The centerpiece is the built-in 4000mAh rechargeable Lithium-Ion battery. In our tests, we consistently got between 16 and 18 hours of listening time at a moderate volume on a single charge, right in line with the manufacturer’s claims. This is more than enough to get through a full day and night of a power outage. Charging is handled via a modern USB-C port, a welcome feature that means we could use the same cable as our newer phones and laptops. A full charge from empty took just under 5 hours. What truly elevates this radio into a serious preparedness tool, however, is the backup option: a compartment for four D-cell batteries. This is a game-changer. While the internal battery is convenient for daily use, the ability to pop in a fresh set of common D-cells means you can have power for weeks, if not months, during a prolonged grid-down scenario. This versatility provides immense peace of mind, ensuring you’ll never be left in silence. This robust power system is a feature that really sets it apart in its price category.
Tuning In the World: Reception Quality Across the Bands
A multi-band radio is only as good as its receiver. We tested the Jazmm across all four of its supported bands: FM, AM, Shortwave (SW), and Weather Band (WB). On the FM band, performance was stellar. The digital tuner locked onto stations cleanly and powerfully, and as one user noted, the sound through stereo headphones was impressively rich and clear for strong stations. For everyday listening to local music and news, it’s fantastic. The WB band also performed flawlessly. With a touch of a button, it scanned and locked onto the nearest NOAA weather broadcast, delivering crisp, clear alerts and forecasts—an absolutely essential feature for storm preparedness.
Performance on the AM and SW bands was more of a mixed bag, confirming reports from other users. In our suburban testing location, AM reception was adequate for strong local stations but struggled with more distant ones, picking up some background noise. One user reported very poor AM reception while in a car, which is a common issue for portable radios due to interference. The Shortwave band, the feature that attracts many hobbyists, proved to be highly variable. On a clear night, with the long telescoping antenna fully extended, we were able to pull in a few international broadcasters like Radio Havana Cuba and the BBC World Service. However, on other attempts, we were met with only static. This aligns with user feedback, where some found it worked well while one reported they “can not receive any ‘Short Wave’ channels.” This isn’t necessarily a defect, but a reality of shortwave listening: it is highly dependent on your location, time of day, and atmospheric conditions. For casual exploration of the world band, it’s a fun feature, but serious SW DXers will want a more sensitive receiver.
More Than a Radio: The Built-in MP3 Player and Audio Experience
Where the Jazmm radio truly shines is in its role as a multimedia hub. The inclusion of a Micro SD card slot and a USB port for MP3 playback is a brilliant feature that adds tremendous value. We loaded a 32GB Micro SD card with hours of music and podcasts, and the radio handled it beautifully. The controls allow you to skip tracks and play/pause, effectively turning the device into a standalone boombox. This is perfect for camping trips, workshop background music, or simply having a curated playlist ready for a power outage. As one user happily stated, “I have recorded some music on a micro Sd chip and it plays it beautifully.” The audio from the 2-watt “big speaker” is loud and clear, especially for spoken word content like news and podcasts. For music, it’s perfectly listenable and room-filling, though it lacks deep bass and audiophile-level nuance. We also confirmed a user’s finding that plugging the headphone output into a larger speaker, like a Bose, yields a strong, high-volume signal. We did notice the “little pops” between MP3 tracks that one user mentioned; they are subtle but present, something that might bother a discerning audiophile but is easily ignored during casual listening. The versatility of having your own media on-demand is a fantastic addition, making the Jazmm radio a complete entertainment solution.
Design and Usability: Built for Easy Operation
Beyond the technical specs, a device’s daily usability is paramount. The Jazmm radio is exceptionally easy to operate, making it suitable for all ages and technical skill levels. The large, backlit display is the standout feature here. It clearly shows the frequency, band, battery level, and mode, and is perfectly legible in bright daylight or a dark room. An older user with arthritis and vision issues specifically praised this display and the radio’s light weight, calling it their “constant companion.” The physical knobs for volume and tuning have a positive, tactile feel, and the push buttons for other functions are responsive. We found setting station presets to be straightforward, allowing for quick access to our favorite channels. While one user rightly critiqued the instruction manual’s “Chinglish,” we found the radio’s operation to be so intuitive that the manual was barely necessary. Everything from switching bands to navigating MP3 folders is simple and logical. The combination of a thoughtful layout, large screen, and sturdy handle makes this a device that is genuinely a pleasure to use day-to-day, a sentiment echoed by a user who, a year after purchase, was “marveling at how well it still works.” For those seeking a hassle-free experience, the Jazmm radio is available to check out online.
What Other Users Are Saying
Sifting through feedback from other users, a clear picture of the Jazmm radio emerges, largely aligning with our own findings. On the positive side, praise is abundant for its core functionalities. One user celebrated its “good sound and good reception,” particularly highlighting the excellent performance on FM and Weather bands and the flawless playback from their SD card. Another, who typically never writes reviews, felt compelled to share how impressed they were with the radio’s durability, sound, and ease of use even a year after purchase. The user-friendly design is a recurring theme, with one buyer noting the “excellent design features” like the digital display and multiple power options made it a great gift.
However, the feedback isn’t universally glowing. The most significant critiques center on reception variability and quality control. One user had a completely negative experience, receiving a defective unit that failed entirely, leading them to question the product’s quality control. Another found the radio’s reception, specifically for AM and Shortwave, to be “very poor” while traveling in a car, noting it was susceptible to interference. This confirms our assessment that performance on these bands can be highly dependent on the listening environment. These critiques are important as they highlight potential inconsistencies that buyers should be aware of.
How Does the Jazmm Radio Compare to the Alternatives?
The Jazmm radio occupies a sweet spot of features and price, but it exists in a competitive market. To understand its place, we compared it to three notable alternatives, each catering to a slightly different user.
1. Eton Elite Executive Radio
- Comprehensive Coverage: Receives AM, FM, Longwave, and Shortwave (SW) frequencies with precise digital manual, automatic, or keypad tuning, ensuring you stay connected to global broadcasts.
- Superior Signal Quality: Features PLL synthesized digital dual conversion for unmatched tuning accuracy, while a synchronous tuning circuit reduces distortion and fading for crystal-clear audio.
- Advanced Shortwave Listening: Includes Single Sideband (SSB) for access to amateur radio, maritime, aeronautical, and military signals, enhancing your shortwave experience.
The Eton Elite Executive is aimed squarely at the serious radio enthusiast and world traveler. Its key advantage over the Jazmm is the inclusion of Single Sideband (SSB) and Aircraft Band reception, which are essential for hardcore shortwave listeners and aviation hobbyists. The build quality feels more premium, and it includes a handsome leather case. However, it lacks the Jazmm’s built-in MP3 player and its robust dual-power system is simpler, relying on standard batteries or an AC adapter without the large internal rechargeable cell. You should choose the Eton if your primary goal is high-performance shortwave listening with SSB capability and you value a more compact, premium form factor over multimedia features and emergency power flexibility.
2. Kaito PL-380 PLL Radio Receiver
- Powered by RioRand Advanced Technology
- Seven Tuning Mode Selectable,LCD Display Screen,550 Preset Memories,Digital Clock Function With 12/24 Hour Format,Highly Intelligent On / Off Switch
- Using Silicon Labs Si4734 DSP; To Digitalize The Analog MW / FM / SW Broadcasting Signal Base On The Modern Software Technology And Radio Principles
The TECSUN PL-380 (often sold under the Kaito brand) is all about packing maximum reception power into a minimal space. Its greatest strength is its Digital Signal Processing (DSP) chip, which provides excellent sensitivity and selectivity, often pulling in weak stations more clearly than larger radios. It’s significantly smaller and lighter than the Jazmm, making it the superior choice for backpacking or packing in a carry-on. The trade-off is a much smaller speaker, no MP3 playback, and no NOAA weather alert function. The PL-380 is the perfect alternative for someone who prioritizes reception quality and portability above all else and doesn’t need the emergency or multimedia features of the Jazmm.

The Emgykit R11 is the Jazmm’s closest competitor in the emergency preparedness space. It matches the Jazmm’s 4000mAh battery and NOAA alerts but adds even more survival-focused features: a solar panel, a hand crank for charging, a built-in flashlight, a compass, and Bluetooth connectivity. This makes it an arguably more complete “all-in-one” survival gadget. However, its design is more utilitarian and less focused on being a pleasant daily-use radio. The Jazmm offers a larger speaker and a more traditional, user-friendly radio interface. Choose the Emgykit if you want the ultimate multi-tool for a bug-out bag with every conceivable power option. Choose the Jazmm if you want a superior everyday listening experience that also happens to be an excellent emergency radio.
Our Final Verdict: Is the Jazmm Radio the Right Choice For You?
After extensive testing, we can confidently say that the Jazmm Portable AM FM Shortwave Radio Rechargeable is a highly versatile and capable device that successfully bridges the gap between an everyday entertainer and a crucial emergency tool. Its greatest strengths lie in its fantastic dual-power system, clear NOAA weather alerts, excellent FM reception, and the incredibly useful addition of an MP3 player. It’s user-friendly, has a great screen, and produces loud, clear audio for its class.
Its weaknesses, primarily inconsistent AM/SW reception and potential quality control issues noted by some users, are important considerations. It’s not the top choice for a dedicated shortwave hobbyist or someone needing a rugged, mil-spec device. However, for the average household, family, or camper looking for a reliable, feature-packed radio for power outages, outdoor trips, and daily listening, it represents outstanding value. It provides peace of mind and entertainment in a single, easy-to-use package. If you’re looking for a dependable all-rounder that will keep you informed and entertained no matter the situation, we highly recommend you check the latest price and add this radio to your preparedness kit.
