\u26a0\ufe0f Important information on emergency preparedness<\/p>\n

This guide is intended solely to provide general information on emergency preparedness. It is not a substitute for professional advice<\/strong> from qualified personnel or official recommendations.<\/p>\n

Act immediately in an emergency:<\/strong> always try to reach the emergency number 112<\/strong>. You can find official recommendations on crisis preparedness at the Federal Office for Civil Protection and Disaster Assistance (BBK)<\/a>. Last checked: June 2026.<\/p>\n<\/div>\n

During a blackout, your smartphone is your most important tool. You need it for emergency calls, for alerts from the BBK, for communicating with your family \u2014 and for everything you haven\u2019t printed out beforehand.<\/p>\n

The problem: the average battery life of a smartphone is 1\u20132 days. After that, it\u2019s just an expensive paperweight.<\/p>\n

Here are the 6 best ways to charge your mobile phone without electricity<\/strong> \u2014 from immediate solutions to long-term ones.<\/p>\n

Pillar \/ Area<\/th>\nCritical challenge<\/th>\nKey measure<\/th>\nWolf\u2019s unvarnished verdict<\/th>\n<\/tr>\n<\/thead>\n
1. Power bank<\/strong><\/td>\nCapacity only lasts for 1\u20132 days \u2014 not enough for a blackout.<\/td>\nBuy a power bank with at least 20,000 mAh and keep it charged at all times.<\/td>\n\u201cMost power banks last 1\u20132 days. That\u2019s not enough for a week-long blackout.\u201d<\/td>\n<\/tr>\n
2. Solar panel<\/strong><\/td>\nWeather dependence and panels that are too small render them useless.<\/td>\nFoldable solar panel, min. 20W, for balcony\/window \u2014 can also be used in winter.<\/td>\n\u201cIn winter, with only 4 hours of sunshine, you need an efficient panel, not a toy.\u201d<\/td>\n<\/tr>\n
3. Battery management<\/strong><\/td>\nApps and the display drain the battery within hours.<\/td>\nSwitch to flight mode, send only emergency texts, and reserve the battery for emergency calls.<\/td>\n\u201cNo Netflix, no TikTok. Save the battery for what matters.\u201d<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Why your mobile is vital for survival during a blackout<\/h2>\n

The \u201cCell Broadcast\u201d warning system sends emergency alerts directly to your mobile \u2014 no app, no internet, just via the mobile network. As long as the masts are operational (they usually have emergency power for 24\u201372 hours), you can receive official information via this system.<\/p>\n

Also: coordinating with family, photos of important documents, offline maps, torch app.<\/p>\n

In short: an empty mobile phone during a blackout is a real safety risk.<\/strong><\/p>\n
