Have you ever thought of getting a wireless speaker with almost day-long battery life at an affordable price? The Ubon solar wireless speaker SP-40 is like that. The Bluetooth speaker comes with a small solar pane on top, that charges the speaker while you enjoy the music.
Built quality
It looks like any other wireless speaker out there. The outer shell is made of solid plastic and has a metallic speaker grill with Ubon branding. On the left side, it has a LED flashlight and on the right, it has all the control buttons – volume, modes and play/pause. At the back, it has multiple ports including USB Port, a Micro TF/SD power on/off, a flashlight on/off and a micro USB port. Also, the back holds another light with multiple small LEDs.
The solar speaker features FM Radio and supports TF cards. Using the mode button you can switch to FM, Bluetooth and USB modes. On the top, it has a solar panel along with a foldable FM antenna. The wireless speaker is powered with a 1200 mAh battery that can be charged by the connecting charger to the MicroUSB port or just put the device in the sunlight.
Ubon SP-40: Detailed Look
Performance
The solar speaker comes with Bluetooth version 5 that makes pairing easy and snappy. The wireless range is also higher compared to the previous-gen. You can stream music at a distance of up to 10 meters. We connected multiple devices to the speaker, there was no issue in pairing a new or switching from previously connected devices. Also, we didn’t notice any connectivity issue till 7 to 8 meters, without any obstacle, however over that there was a little drop in the connectivity.
Both flashlights are powerful to bright the dark, one can be used as room light another as a torch.
Ubon has included a 5w mono speaker which produces an ample amount of sound. It can easily fill a small. Ubon solar speaker handled the lows, mids and highs quite well. Just at high volume, there was cranky sound and sometimes the sound was floundering. I played songs of various genres in different file formats like FLAC, mp3, ALAC, and WAV. It sounds well on low, mid and just high are not that great. It has maintained the balance between bass and treble, which you can notice at low and mid.
Battery life
If you forget the solar panel, then it can run for around 4 hours with moderate usage. But if you put it in a room where it can get an ample amount of sunlight then you can run it for a longer time. For me, it was more than 8 hours when I kept it in the direct sunlight.
Charging the 1200 mAh battery can take around 1 hour with electricity with solar it depends on the weather conditions, yet around 3 to 4 hours from zero to 100 per cent.
