Detailed overview
The T6 Plus isn't a power bank but a Bluetooth speaker, among the best on the market. The reason it's in this ranking is that it has a handy backup external-battery function (two 3300mAh lithium batteries each, holding their charge for 24 months). On the technical side, this aluminum and ABS plastic speaker, water resistant, is Bluetooth 5.0 compatible with a max range of 20m, and has a hands-free function and voice control (compatible with Amazon Echo and Google Alexa). It offers 15 hours of playback battery life (20 hours in call mode) and charges in 3-5 hours via its micro-USB input.
