Both the lightpipe of the e-mark as well as the App indicate the level of battery. The left LED on the back side of the e-mark shines either green, yellow or red. The battery level can also be found on the e-mark connect page in the App. If you are connected with your e-mark, the exact level (%) of battery is displayed in the upper part.
How do I know that the battery needs to be charged?
Below a battery level of 25 % the e-mark shines yellow in the back. The same LED is shining red if the battery is below 10 %. In addition to that, the App gives you a warning when your battery is low and needs to be charged. Please charge the e-mark when the yellow LED lights up.
How can I see that the battery is charging?
When the e-mark is turned on, lights on the back of the e-mark provide a status indication of charging. A yellow blinking light means, that the the battery is still below 50 %. A green blinking light indicates a battery level between 50 and 99 % and a steady green light indicates a full battery. You can also follow the state of the battery in the App on top of the e-mark connect page. Note that there is no indication for charging when the e-mark is turned off.
How long does the battery of the e-mark last?
The battery lasts up to five hours when printing continuously and much longer under normal usage circumstances - several days up to a week when used occasionally. The battery is charged within around 3 hours from 0 to 100 %. Nevertheless, you can also charge your e-mark (which is always in the docking station anyways) while usage.
