11 Travel Essentials Every Traveler Should Use

8. Portable phone charger / power bank

A power bank is essential when outlets are scarce. Choose a capacity that matches your phone and travel habits; 10,000–20,000 mAh suits most day trips and short flights. For international flights, check airline rules—most carriers restrict spare lithium batteries in checked luggage, so keep the power bank in your carry-on. Prefer models with USB-C Power Delivery for faster charging and wider device compatibility. Carry a short charging cable in the same pouch as your adapter to avoid hunting for cords. If you plan long days out sightseeing, charge the bank fully each night and use low-power mode on your phone to stretch battery life. For longer overseas travel, consider carrying two smaller banks rather than one huge unit; redundancy helps if one fails. Buy quality banks with safety certifications to reduce fire risk. In India, popular brands and certified models are widely available; international travelers can decide whether to buy locally or bring from home based on warranty and voltage compatibility.
