Prolonged use, accidents, and forgetfulness can result in the need to find a replacement laptop charger. Often, OEM replacements prove the simplest option since they offer compatibility in terms of voltage and proper connector for the charger port, but the cost may deter some buyers.
Universal laptop charger models typically offer a more affordable option; however, they do not necessarily work with all laptops and may require an adapter in order to fit your laptop's charging port. However, they do offer the possibility to charge multiple models as opposed to the specificity of one from the manufacturer. Other options include travel models that come in a compact and light form factor and may even plug into the car's cigarette lighter as well as solar-powered chargers that do not require mains power. In general, it is important to look up the charger specifications and checking the port type to avoid damaging your laptop and ensure the right fit.
