Dell laptop AC adapters are made of the most rugged materials for the sake of portability and durability. The transformer casing of modern Dell AC adapters are made of extremely durable plastic to withstand any drops, kicks, or other wear and tear they may have to endure in the course of regular use. The cables themselves are also quite durable, as they are reinforced at all joints and are quite thick. When storing the AC adapter, both cables can be neatly wrapped around the transformer and secured with a flexible band attached to the adapter. This is a very convenient feature that makes Dell's AC adapters more portable than most.
Dell laptop AC adapters come in a range of configurations depending on the model. Most have a range of 15 to 20 volts, and provide anywhere from 60 to 90 watts. In the case of Dell's Alienware line of laptops, AC adapters sometimes provide up to 150 watts to handle the higher demands of these high-performance machines. The connectors for each adapter are purposely designed to be different, to avoid a user accidentally plugging an incompatible ac adapter into a laptop, which could cause damage. For example, one ac adapter may have a 5.5mm x 2.15mm connector, while another may have a 7.45mm x 5mm connecter. This is particularly necessary for AC adapters that may look similar in design but have different power output. When purchasing a replacement AC adapter, or an additional AC adapter for your Dell laptop, it is important to ensure you have the correct adapter for your model. Most retailers of laptop parts will carry a laptop AC adapter that is compatible with your model. |
