Eight-pack solar calculator for shared use

This pack delivers eight identical 12-digit desktop calculators that run on solar cells with an AA-battery backup. Each unit weighs 125 grams and measures 14.5 by 11.9 by 4.6 centimetres, so they stack neatly in a drawer or travel in a bag. The raised keys and automatic power-off help reduce entry errors during long sessions.

Suited to classrooms and offices needing volume

Teachers, accountants and students who want a reliable basic calculator for every desk will find the quantity convenient. Buyers who need scientific functions, programmable memory or a backlit display should look elsewhere because this model only handles the four standard arithmetic operations.

Fits any workspace with a light source

The dual-power design means the calculators operate under normal office lighting without batteries, while the AA option keeps them running in dim conditions. No cables, software or special mounts are required; simply place them on a flat surface or hand them out for mobile use.

Questions about this item

What batteries do I need to keep the 12-digit display readable in low light?

Insert two AA batteries, which are not included, to power the calculator when solar energy is insufficient.

Will the raised keys and 12-digit LCD still work if I keep using my older desktop calculator beside it?

Yes, each unit operates independently on solar or battery power, so it functions normally alongside any other calculator.

How can I confirm the auto-off feature is active after I set up the pack?

Leave a calculator idle for a few minutes; the 12-digit LCD will blank automatically to save power.
