The Sharp EL-1801V Ink Printing Calculator is a solid choice for individuals who frequently handle financial calculations, such as business owners or accountants. Its large 12-digit blue fluorescent display makes it easy to read numbers, which is a significant plus for users who need to view results clearly. The two-color ink printer adds a professional touch, allowing users to print calculations in black and red, which can be useful for differentiating between regular and negative values or errors. The one-touch change calculation function and dedicated keys for cost, selling price, and margin calculations streamline the process, making it user-friendly for those engaged in financial tasks.

Portability can be a bit of a mixed bag; while it is lightweight at just 2 pounds, the fact that it operates on AC power means it's not as portable as battery-powered calculators. This could limit its use in environments without easy access to electrical outlets. Durability is decent, although it's always a good idea to handle it with care since it's primarily designed for desk use.

In terms of battery life, the calculator requires a lithium metal battery for backup, but since it operates mainly on AC, users might not find this aspect as critical. However, it's good to keep in mind if you're in an area prone to power outages. If you're looking for a reliable financial calculator that combines functionality with ease of use, the Sharp EL-1801V is a strong contender, though you may want to consider your need for portability and reliance on AC power.

This feature is especially beneficial for beginners or those who may not frequently use financial calculators. The ten-digit display is clear and easy to read, adding to its user-friendliness.

In terms of durability and portability, the BA II Plus Professional is lightweight (just 3.84 ounces) and compact enough to fit in a bag or pocket, making it convenient for on-the-go use. Additionally, the automatic power-down feature helps conserve battery life, which is a plus for those who want to avoid frequent battery replacements. There are some drawbacks to consider. While the calculator is excellent for financial calculations, its engineering/scientific capabilities might be limited for those who require extensive scientific functions. Also, some users have reported that the buttons can feel slightly stiff, which may impact usability for extended sessions.

The calculator is battery-powered, using 2 CR2 batteries, which are included in the package. Users have noted good battery life, meaning fewer interruptions during important calculations. Weighing only 3 ounces and with compact dimensions, it is highly portable and easy to carry around in a bag or pocket.
