Only in one review: Current 3 A (Vapcell S4 plus); Test current 3 A (Vapcell S4 plus); Weight 330 g (Vapcell S4 plus).
Vapcell S4 plus: Charges and measures capacity well, but lacks LiFePO4 support and recharges very slowly after a test at 250 mA.
12.6 V 350 mA charger: The charger is well assembled, but its measured 210 mA charging current is below the stated 350 mA.
