{"product_id":"9v-battery-snap-to-dc-barrel-jack-adapter-compoden","title":"9V Battery Snap to DC Barrel Jack Adapter | Compoden","description":"\u003cp\u003eUse this adapter to plug a standard 9V (PP3) battery straight into an Arduino Uno\/Mega barrel jack — snap on one end, 5.5×2.1mm centre-positive barrel plug on the other. The quickest portable power for a controller: no soldering, no breadboard rail. Commonly used for demo rigs, science-fair projects, and any bench test that needs to walk. Not suitable for motor loads — a PP3 sources well under 500mA usefully and sags fast; power motors from their own pack and share ground. Key specs: PP3 snap, 5.5×2.1mm centre-positive plug, ~120mm lead. Alternative: the 6x AA holder with barrel jack for far more capacity at the same 9V.\u003c\/p\u003e\u003cp style=\"font-size:.8em;opacity:.7;\"\u003eProduct photo: oomlout, CC BY-SA 2.0, via Wikimedia Commons.\u003c\/p\u003e","brand":"Compoden","offers":[{"title":"Default Title","offer_id":53782639739245,"sku":"CDN-3084","price":49.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0999\/3997\/5533\/files\/9_volt_battery_snap_to_2.1_mm_DC_adapter.jpg?v=1787397175","url":"https:\/\/compoden.com\/products\/9v-battery-snap-to-dc-barrel-jack-adapter-compoden","provider":"Compoden","version":"1.0","type":"link"}
