So whats this like ? comes with a usb cable for charging and comes with some charge , rechargable from mains with an adaptor, or from either a power bank or solar charger. Small at about 10cm x 7.5 x 5 and light enough for a pocket. comes with a wrist strap and telescopic antenna. Operated by glove friendly buttons, set up and station/frequency selection is simple while the largish led display is clear and readable. sound is suprisingly loud for such a small unit and makes clear hearing in or outside, though I would suggest headphones for in public or force 6 gales. Frequencies, FM = Well its fm, chosen for all commercial radio and prone to drop out and static when on the move or inside steel frame buildings, needs ariel moving for best reception, only marginally better than original dab. AM = far less stations but those you do find tend to be more stable and not suffering the problems of FM. SW = The least populated frequency, but unlike the others is not limited to local range, in the right circumstances can pick up signals in areas the others cant and from all over the world. normally apart from occasional stations, this is a field of static, but in an emergency local or global, this frequency will carry official information to the public, along with ham operators long after FM/AM/INTERNET/DAB has been disrupted. like insurance, sw should hopefully never be needed, but if it is then you will be glad you have it, and this neat, light and clear radio along with a good travel solar charger should have a place in every home, if only for the fun of trying to find a station. ### ⭐⭐⭐⭐⭐ Good quality, good sound, good value. *by on Reviewed in the United Kingdom 28 August 2020* Very good value, clear crisp rich sound from a neat compact and robust unit. I am impressed that such a relatively small player produces such a good sound. It plays MP3 files if you insert a micro SD card in the slot underneath. The radio has good reception even though the aerial is quite short. You can select the mode easily, (FM, AM and SW radio and MP3 player.) using the button marked M. In MP3 mode you can pause playback, and if you switch off, when you turn the player back on it continues from where you left off. You can also select any MP3 file by pressing the buttons if you know the track number, or you can scroll up and down using the arrow buttons. The battery is easily charged using a standard usb charger (not supplied) or I think you can plug it into your computer and charge it that way, although I haven't tried it. The battery lasts for hours on a single charge.All in all a very good piece of kit, and good value too. ### ⭐⭐⭐⭐ Small, easy to use, the battery lasts a while. *by on Reviewed in the United Kingdom 4 August 2018* Needed a small radio at work and this does the job for me. It's small, the construction is solid and it works pretty well.The only thing I will say is the sound from such as small device while adequate isn't going to blow your mind and the louder you have it the less battery life you get. 4 - 6 hours depending on volume from full to dead. But because it runs on a mobile phone battery you can just plug in your MINI usb adapter and charge it. This device might have been more versatile with a MICRO usb adapter instead which is more ubiquitous especially among android phone users. You can power it off a usb powerbar, beware that charging other devices near it can sometimes cause interference with the the radio.Tuning is easy enough, it's got an auto scan function but it's just as easy to type in a frequency. The display is nice and clear for radio use, I've not used it to play Mp3 which apparently it can do also. There are no points in the display, so for example 89.3fm is 893.You can plug other devices into it and also use the headphone socket to connect to a separate amp or speaker also.For what it is it's a decent quality item. ## Frequently Bought Together - PRUNUS J-429SW Portable Radios Small AM/FM/SW, Rechargeable Radio with AUX/SD/TF/MP3 Speaker.
