Currently there are more and more companies selling ultra-low cost laptop ac adapters in market. \u00a0These power adapter sellers base their business model on selling the lowest cost laptop chargers<\/a> that they can obtain. \u00a0The problem is that to reduce cost, the factories use cheaper materials and also omit important filtering and safety components. \u00a0While these laptop adapters may work, their designs can place unnecessary stress on the internal components of your computer and could compromise safety.<\/p>\n

Input & Output Filtering<\/h3>\n

Surges, spikes, noise, and other power quality problems are found in most AC wall outlets. \u00a0Surges and noise place extra stress on the internal components in your computer that could lead to failures or cause strange transient problems in computer operation. \u00a0In extreme cases, the energy could be great enough to cause immediate damage.<\/p>\n

Quality power adapters include input and output filters that are designed to supress surges and reduce the effects of poor AC power. \u00a0Better filter circuits use a group of several components that work together to provide a higher level of protection. \u00a0Low cost adapters use only the most basic filters that often have only a single component. \u00a0Cutting corners on the filtering can save some cost, however it will also increase the chances that your computer will be affected by a power quality problems.<\/p>\n

Outside Appearance<\/h3>\n

For the most part a quality adapter and a low-cost adapter look pretty close from the outside. \u00a0This similar appearance makes it hard for people to determine an adapter’s quality from the small photo on a website.<\/p>\n

When you look at the adapters side by side, one clear difference is the size of the cable that goes to the computer. \u00a0Reducing the size of the wires is a common cost-cutting tactic. \u00a0Thinner wires with less insulation separating them and less rubber protecting the wire to box connection will fail more quickly under day to day stress. \u00a0There is also a safety issue involved. \u00a0If the cable begins to break, the electricty must squeeze down a smaller path. \u00a0This can cause the wires to overheat, melt, and possibly catch on fire. \u00a0The heavier cable found on quality adapters will resist damage and if it is damaged, the larger wires will have less of a chance to overheat.<\/p>\n

Inside Components<\/h3>\n

If you look inside of these two adapters you will see quite a few differences that highlight how low-cost adapters cut corners on important protection and safety components to make a “cheap” product.<\/p>\n

Vibration & Short-circuit protections<\/h3>\n

Laptop Adapters have a hard life. \u00a0They are often dropped, kicked under desks, fall off tables, or otherwise treated roughly. \u00a0The result can be internal components that shift or break. \u00a0If these components touch it can cause the\u00a090W ACER Aspire 5590 Series Power Adapter<\/a><\/span> to fail or even create a fire or electric shock hazard.<\/p>\n

Quality adapters glue large components & structures together. \u00a0This allows these components to support each other and reduces the chances of the components shifting or breaking as the result of a physical shock. \u00a0 These adapters also include insulation tape placed a key locations to prevent shorting in case some components do shift. Low cost adapters often omit these protections to reduce cost. \u00a0Omitting these protections makes the adapter less durable and possibly subject to a safety problem.<\/p>\n","protected":false},"excerpt":{"rendered":"
