Apart from your passport and credit card, the chargers are probably the most important thing you bring on your travels. In this modern time with everything is running on battery, being able to charge is essential. We basically has two options, either in the car or the bus/train (if you are lucky), or in the place you are staying for the night. Most people will rely on the latter I guess, and that may bring a challenge in itself. For us, we bring a laptop, a tablet, two telephones, rechargeable speaker and two to three cameras that sometimes all need to be charged for the next day.
