Battery Life & Audio Quality

That’s all very well and good, but a portable Bluetooth speaker needs to have a decent battery life if its to be successful. The good news is that the Cowin Thunder boasts a lithium-ion rechargeable battery, which can be charged via any micro-USB cable. Cowin claims that the Thunder has an average battery life of around eight hours, though we found this would depend on a number of factors containing volume and whether or not we were using its normal mode, or lightning mode.

The Cowin Thunder is a 15-W Bluetooth speaker, which should be loud enough for casual social occasions, but is not ideal for hosting a house party. Nevertheless, with this being said, using Lightning mode did amend its prospects, providing a more rounded audio experience. It is worth mentioning that even when Lightning mode is active, the bass, while more prominent, is not quite as strong as we would like, though this means there is no danger of the bass levels drowning out the mid-range or vocals.


When Thunder is attached to a table/window/box, you can activate its Lightning mode, which utilizes the built-in vibration technology to turn the surface into a giant speaker. Connectivity wise, the Thunder boasts Bluetooth with NFC support for one-tap pairing.

The Thunder also boasts speakerphone capabilities via Bluetooth, so if you are playing music and get a call, there is no need to disconnect the device. We found that Lightning mode really had an effect when placed on boxes, though you have to experiment with objects around your home to find which creates the best sound.


It is a fairly powerful portable Bluetooth speaker, and the addition of its lightning mode offers something little different and makes it stand out from the crowd.
