Ranked in these QuestionsQuestion Ranking
Pro Great for scanning difficult surfaces, such as books
Unlike most scanners, this TaoTronics can scan almost any surface, since it's handheld. For example it's easy to scan books, which would not fit into a sheet-fed or flatbed scanner, where the paper has to go through or into the scanner.
Pro High quality scanning
It's capable of scanning at a 1050 DPI(dots per inch) resolution, which results in a sharp scanned image quality. This maximum resolution is similar to the one found in more expensive alternatives.
Pro Extremely portable
This is one of the smallest and lightest scanners available on the market. It weighs just 5.9 ounces and measures 10.5 x 1 x 1.2 inches.
Pro Lets you save scanned documents on an SD card
You can add an SD card up to 32 GB in size and the scanner automatically saves the documents on it.
Pro Color display for convenient settings adjustment
The scanner has a small color display, which makes it easier to do operations such as changing the scan settings or choosing the output format.
It's a great budget option if you know you'll just need to scan documents during one specific project and don't want to spend a fortune on a scanner. Portable scanners, especially the ones that are not handheld, often cost 5-10 times more than this one.
Con Each scan creates a new PDF
There is no option to scan several pages into one PDF file. This can be a headache when scanning documents longer than one page, since you will end up with a lot of PDF files. Luckily, there is free software available online that lets you merge several PDF files into one. Of course, this takes some extra effort.
Con Poor character recognition software
Optical Character Recognition (OCR) software transforms a scanned picture into editable text. The OCR that this scanner comes with is not capable of consistently reading characters accurately. Also, this software is not Mac or Windows 10 compatible — it was made for older Windows operating systems. Of course, you can always get other OCR software that is compatible with your system.
Con Requires some practice
Scanning with a handheld scanner requires some skill and practice. The first scans might not be perfect, due to improper speed or unstable movement of the scanner.
