Techradar.com: The problem with portable DABs is that the battery life on DAB radios to date has been pretty poor.
Roberts is making a concerted effort to address this problem for DAB listeners on-the-go, launching four new portables that it claims “offer unbeatable battery life.”
The ecologic 1 features a built-in battery charger that conveniently recharges the radio’s batteries when plugged into a power socket. Features-wise, the radio packs in the standard 10 station pre-sets, automatic clock and idiot-proof up and down tuning buttons.
The ecologic 2 also packs a built-in battery charger. At the top end of the range the ecologic 3 claims to offer 120 hours battery life while the Gemini 21 offers an awesome 150 hours of battery life.
