Can I use the e-mark without power supply?
Of course – the main advantage of the e-mark is its mobility and flexibility. Its inbuilt battery lasts for up to 5 hours when printing continually and much longer under normal usage circumstances (up to 1-2 weeks). Battery charging takes up to 3 hours from 0 % to 100 %. Use the protective case to transport the e-mark savely from one to another place.
