A portable document scanner is preferred by many people if they are frequent travellers or always on the go and want a perfect companion for their printing and scanning needs. While some critics are not happy with this popularity and have their own reasons to defile this device, the convenience factor is a major plus point.
A portable document scanner, according to major critics, cannot be a substitute for an actual, large size scanner. They are partially right as most of these portable document scanners do not offer as much scanning speed as typical large size equipment. They are however perfect for use during traveling and one cannot take a 20 pounds scanner on a flight and even on a car or train given its mammoth size. It does not just looks awkward but makes traveling difficult and you may even have to pay extra charges if you are traveling by air. Scanning speed is greater in some larger models so you will not face many issues to complete your projects on time.
The second criticism is related to resolution and quality. A standard portable handheld document scanner offers a resolution of around 1200 dpi which is quite a satisfactory figure. Scanning is done at an average rate of one image per 10 seconds so it is an acceptable rate for travelers and even those with average scanning needs. Some scanners have rather slower speed of one image per 20 or 25 seconds. It creates a diversity of choice to suit the needs of different customers.
Almost all portable document scanner reviews gives dimensions and weights of these devices. Still there are some people that argue that these scanners are large and cannot be carried easily. This point is partially valid as there are two types of portable scanners. One type is very small with some having a weight of less than a pound. They can easily be stacked in your backpack. The second type has a weight of around four to five pounds and is little larger. It can still be carried but you will need a large carrying box. The first type is good for people who have an extensive need for these devices and the second type is good for people who want to set up a remote office during their trip to other cities and countries.
Perhaps the best portable document scanner is one that best suits the needs of the user. Size will not matter if you have an extensive scanning requirement. Similarly you will require a very compact scanner if you are always on the go and want to use it during your train commute and flights. A simple focus on resolution, quality and speed will land you the best devices.
