Do you want a rechargeable calculator?
Rechargeable battery: via the USB cable
There are calculators with a rechargeable battery. You can easily charge these via a USB cable. You can charge via a socket, your PC, or even with a power bank in some cases. Charge the calculator regularly, so it won't run out of battery.
Solar cell: via solar energy
Some desk calculators have solar cells. These are often above or just below the display. The desk calculator doesn't have much computing power, so it uses less energy. You can be sure your calculator always has enough power.
Batteries: replace when they're empty
Calculators that don't have a rechargeable battery use batteries. You usually need 4 AA batteries. If your calculator doesn't have a battery indicator, we recommend that you always keep spare batteries in your bag. Make sure your calculator doesn't fail when you have test, so you don't fail as a result.
Is a color display important?
Color display: better overview
Calculators with a color display give you more overview and clarity. This is useful when you have to plot multiple graphs and have to make connections between equations. The readability is much better. Not only because of the colors, but also because of the better resolution.
Black and white screen: no distinction
Most calculators don't have a color display. It's not a necessity, but it helps some users understand outcomings better. A calculator without a color display is relatively more affordable. If you don't think the colors add anything, the standard display is good enough for you.
Are there any other features that are important to you?
Backlit display: work in the dark
There are calculators with an backlit display. This is useful when you work very early or until the late hours. This'll reduce the chance you copy the results incorrectly.
Number of lines: better overview
Getting a calculator with 1 or even 11 lines? That depends on your wishes. More lines provide a better overview or more chaos. Think carefully about what you like.
You can download apps and even games on the larger and more extensive calculators. A good example is the Python app. This teaches you how to program.
