Calculators Desktop, 2026 Upgrade 14 Digit Large Size Calculator with 5-Inch LCD Display and Solar Power
Our verdict: A tilted 14-digit display, soft-touch oversized keys and a long solar panel with battery backup.
The SPLAKS gives you 14 digits on a tilted 5-inch LCD, a standard 10-key layout that mirrors a computer number pad, and oversized soft-touch buttons designed to prevent mis-hits. Power comes mainly from an extra-long solar panel, with a AAA battery as backup. The body measures about 6 by 7.7 inches.
It wins because it solves the three complaints about big-button calculators together: the display is angled, the keys are generous, and two extra digits cover large totals. The 10-key layout is familiar if you type numbers on a keyboard. The listing does not describe a grand total key or a decimal selector, so it is a straight desk calculator rather than a bookkeeping machine.
Buy it for an office desk, a retail counter or anyone with limited vision. The caveat is size, as this takes more room than the compact pocket-style models.
