One question I had from those users in this thread. Have you been able to find a battery that airlines will allow you to use?
I bought one from Amazon. When it came it was huge and had a large badge on the front saying “not airline approved” so had to send it back.
Would still like to buy one as per BAs advice but also got some sleeper train journeys due for which it would be most helpful.
Bought one from Amazon (EasyLonger ES400) that advertised “Airline Approved”, but it does also warn different airlines have different rules. I’m not sure what “not airline approved” actually means, as there is no “worldwide standard”. It may have been fine*, but they’re covering their butts. The airlines just tend to say “dry cell”, which is non-lead acid flooded cell types (like car most car batteries), as they can leak, but are updating language on a rolling basis.
*Edit: Noted on another thread that some airlines and countries have a capacity/voltage limit for battery packs. Seems for the U.S. it’s 160Wh and 12v, allowed two in carry on luggage…but there’s also a mention of a 100Wh limit on internal batteries in carry on. Here’s the CAA link for specs:
