A Texas Instruments Calculator AC9132 Adapter and Charger, is up for your consideration. The adapter is rated for 5.7 VAC and 240 mA. 

The Texas Instruments Calculator AC9132, shown in the photos, is the only item included in this listing. The photos were taken on a 1 cm grid. Returns accepted only when the serial number matches the original item purchased.  I will combine multiple items together to reduce shipping costs and will mail one or two business days after receiving cleared payment. 

Questions are welcome. Thanks for stopping by!
