A portable charger offers flexibility since you can take it with you for road trips or use it at multiple locations without the need for permanent installation. This is especially helpful if you move frequently or travel to places without easy access to chargers. Portable chargers don’t require the expense of electrical jobs, as they typically plug into a compatible outlet, saving you installation costs. However, they may have slightly lower charging speeds due to outlet limitations and may wear out faster with constant plugging and unplugging.
On the other hand, wall-mounted chargers are more convenient if you're mostly charging at home. Once installed, they provide easy access without the hassle of setup every time you need a charge. Though they require professional installation and may involve additional electrical jobs, these chargers are typically more durable and can offer faster charging speeds. They're also more weather-resistant and less likely to experience wear and tear compared to portable options.
