Like most electronics, it is no biggie to care for your portable speaker, apart from some basic things. Keep it away from high sunlight and invest in a case too. Plus, make sure that you check its performance every couple of months. Also, use a damp cloth to get rid of dust and dirt. Moreover, though most of them have a waterproof feature, keep them away from the water as much as you can. Not to mention, always charge the speaker entirely before using it. And in case of malfunction, head to the store and don’t try to fix it at home.
