You can personalize the battery backup with your company logo or name. You can also add other information such as your website address or phone number. To do this, you will need to create a graphic file containing the design to be printed on the custom power bank. When choosing the color of your advertising power bank, you must take into account the color of the personalization. Indeed, it must stand out and appear clearly when printed. Therefore, if your logo is dark, choose a light color for your backup battery. Conversely, if the color of your logo or design is light, we recommend that you choose a dark external battery color.
