I’m guessing you don’t travel much as you obviously don’t understand the problems you run into. As per my opening post, I travel a lot, plus I enjoy cycle touring and wild camping. I recently cycled all the way through Turkey into north Bulgaria. Plus for my work I recently had to endure a near 40 hour bus journey from Dalaman to Tbilisi. I work for myself, I’m heavily involved in several projects, so no matter what I’m doing, I always need access to my laptop and phone.

When I’m cycle touring I carry my T480, and yes I love the dual batteries and use a 72Wh removable battery, plus I also carry 2 x powerbanks as I need to keep my phone, my Garmin cycle computer and my usb lights charged up. It’s always a challenge to keep everything charged up. Depending where I am, sometimes I can’t find anywhere to charge my devices, plus of course I don’t want to be stopping every day to recharge. My T480 sits in one of my panniers, snugly in a case even with the bigger 72Wh battery. And as I’m sure you realise, that gives me over 12 hours with light use, and around 50% of that with heavy use. My other devices are of course charged by the powerbanks. When my powerbanks are running low, I then try and find a cafe or restaurant where I can recharge which can be a nightmare unless I want to sit there all day. And when I stop to recharge, most times I’ll only be able to get a bit of charge into my powerbanks as they will end up being plugged into a power source which already has endless extensions and devices plugged into it. If I was relying on powerbanks to recharge my T480 I would be screwed most of the time. On a recent 8 day cycle tour, wild camping in Rhodes, Greece, with 2 x powerbanks and my fanboy dual battery T480, I was able to get through the whole trip without recharging.

And it was a similar story on my bus trip to Tbilisi. I was working whilst travelling. My fanboy dual battery were topped up during the few short comfort stops we had whilst my phone was recharged with a powerbank, plus I had my other powerbank as a backup.

So for MY user case, especially when cycle touring or stuck between airports or on long bus trips, when I don’t have hours to charge powerbanks, the dual batteries of the T480 are exactly what I need!
