Why consider this model?

  • A portable, single-output 120 V AC charger for a 12 V lead-acid AGM use case when a 10 A documented maximum charge capability and automatic post-charge maintenance are relevant; verify the battery maker's permitted rate.

Tradeoffs to weigh

  • The page title/package use SC1339L while its product-form code and pictured face say SC1339; page copy also conflicts on 2 A, 6 V and LiFePO4. The manual states no universal Ah ceiling or fixed maintenance current and requires grounded, dry, ventilated 120 V AC use.
