ZHIWHIS Portable Radio, AM FM Stereo SW NOAA Weather VHF Receiver with Alerts, Rechargeable DSP Pocket Radios with 9.85Ft Wire Antenna, 900mAh/396Presets/Alarm Clock/Sleep Timer for Walking ZWS-878

Compacto, buen diseño, buena recepción en AM, FM, OC y Clima. Es más pequeño que un teléfono móvil así que lo puedes llevar sin ningún problema en el bolsillo. El sonido no es muy alto, pero es bueno. Lo recomiendo. 🫡

I've been using the ZHIWHIS Portable Radio (ZWS-878) mainly to keep NOAA Weather Radio running 24/7 in my greenhouse. The constant talking helps me stay ahead of the weather and seems to keep rodents from making themselves comfortable. After spending some time with it, I’d say it’s a solid little radio with a few quirks.The DSP tuner locks onto NOAA channels well, even inside my greenhouse, where reception can be hit or miss. The included 9.85ft wire antenna makes a real difference, especially for weaker stations. I tested AM, FM, and shortwave briefly. AM reception is fair, FM and shortwave perform much better with the external antenna. NOAA comes in clearly, which is what matters most for my use.The radio is small and lightweight, easy to move around if needed. The screen is clear enough but not particularly bright. It has 396 preset slots, more than I’ll ever use, but nice to have for scanning. The sleep timer and alarm clock work fine, though they’re not relevant to my setup.The 900mAh battery holds a charge for quite a while, but since I leave it on NOAA all the time, I keep it plugged in. It charges via USB, which is convenient. If I were using it on the go, I’d expect to recharge it every couple of days, depending on volume and signal strength.The speaker is fine for speech, but the sound quality isn’t great for music. It has a bit of a tinny quality, which isn’t surprising for something this size. The button layout isn’t the most intuitive, so it takes some trial and error to get used to navigating presets and features. There’s no battery indicator, which makes it hard to gauge when it needs a charge if it’s not plugged in.

Very nice little radio. But it doesn't keep a very good charge at all.

Works well on all bands tested, even the weather.Sensitivity is pretty good with a long wire attached for shortwave.Don't expect a DX machine for a radio in this class.GREAT audio with headphones.Some of these cheapies have a hiss or poor dynamic range.

This thing sounds great for its small size! I was very impressed when I turned it on and heard how good the audio is.The inclusion of stereo FM (only when using headphones) is a nice feature that many radios don't have nowadays.I was then quite impressed by how sensitive it is to weaker stations, especially on AM! I had no picking up a handful of DX stations inside my house with the built-in ferrite bar antenna.NOAA is a handy addition, and given how small this radio is, I can see it being someone's emergency radio for power outages and severe weather events.Shortwave reception is pretty good for a small pocket radio. Of course, its no communications receiver, but I was able to quickly find a few stations using the built-in whip antenna and nothing extra connected to it. It would have been nice for this band to go all the way to 30 MHz instead of stopping at 21.95.VHF band is... a mixed bag. The coverage from 30MHz to 199.975 is a great feature, and its nice that the deviation / bandwidth can be adjusted, but the stepping is too course, even on Narrow FM. It goes in 25kHz steps, and it really should go in 5kHz steps. There's a couple areas of interest that would greatly benefit from the smaller stepping and those are the 6 meter and 2 meter amateur radio bands. As this radio is, it is impossible to tune directly to most of my local repeater frequencies because they lie in between steps on this radio.What would make it even better? RDS decoding, and perhaps HD Radio, but the hardware would need a major redesign for those and they are out of the scope of this design. Inclusion of these is just wishful thinking on my end.Overall, its a GREAT radio for what it is. If the limitations I outlined above about VHF and the Shortwave bands don't bother you for what you're interested in listening to, I can highly recommend this. Unfortunately, given those two limitations I can't give it a full 5/5.

This is a fairly decent small portable radio. This is operated by a built in battery. This has many different functions and I have noticed that if I am not careful I will have a dead battery the next time I attempt to use it. I like to listen to AM DX at night and this does a decent job. This has NOAA weather coverage and works well but time will tell if this service will fall under the South Africans axe. The FM section seems to be decent but I live in a FM wasteland. I do have a blowtorch FM station near by that can sometimes be an issue with cheaper radios but this one seems to deal well with rejection of that channel. I like this and I like it in my travel radio pouch. Great for the money on this one.

One of the reason's I'd want a radio like this is for emergencies. The problem is that this radio did not hold a charge over time. I charged it up a few weeks ago, went to use it today and it was totally dead. It doesn't take that long to charge, and it does use standard USB-C, but that it couldn't hold a charge for a few weeks doesn't inspire confidence.I was able to easily pick up my local AM/FM/WB stations. Shortwave I could hear that someone was broadcasting on a few channels, but there was so much interference that I couldn't understand it.The built in speaker can get quite loud.
