12-Digit Desktop Calculator with Solar and AA Power

Check everyday figures at a desk without opening a phone app. This twelve-digit calculator suits home and office users who want a dedicated display and basic calculation controls.

• ✅ Read longer figures — The LCD accommodates up to twelve digits.
• ✅ Use light as one power source — A solar panel provides the stated daylight-power option.
• ✅ Add battery power for suitable conditions — An AA cell provides the second power source.

A Dedicated Calculator Beside Your Paperwork

Use the calculator for ordinary arithmetic when checking bills, notes or other daily figures. The large display gives results their own place on the desk.

The stated power arrangement uses solar energy and an AA battery. The battery is not included; specialised scientific or financial functions are not confirmed.
