Tronsmart is a company that made its name with power elements for smartphones, including external batteries and charges (Quick Charge), but the company also made quite a few portable speakers.

Tronsmart Element Mega SoundPulse is a 2x20W speaker supporting Bluetooth 5.0 and coming with 2x3300 mAh battery that can play for up to 15 hours. The battery life depends on the volume level, and it will range.
Let’s start with the basic, the 657.3 gram / 23.18 oz speaker measures 7.59x2.28x3.14in / 193x58x80mm (L x W x H) which doesn’t make it the lightest but traditionally good quality sound involves some heavier speakers. The driver unit has a frequency range of 115Hz - 13KHz and 4Ω 20W/53mm with less than 1 percent distortion.
