Can I Charge A 19V Laptop With A 12V Charger?
Can I Charge A 19V Laptop With A 12V Charger? NO you cannot charge your 12V AGM battery directly with a 19V Laptop power supply. You need a battery charger. The laptop power supply IS NOT a battery charger, it is a fixed voltage SMPS power supply. Can I use 12V charger for 19V laptop?
