• Can I use a regular USB-C phone charger to charge these?

  Yes, each D battery has a built-in USB-C port — charge with any standard 5V USB-C charger (phone, laptop, power bank, car charger). No dedicated charger needed. The included 4-in-1 USB-C cable charges all 4 batteries at once.

• How long does a full charge take?

  Full charge: ~4-5 hours with 5V/2A USB-C charger (higher output may slightly reduce time). LED flashes while charging, stays solid when done.

• Can I charge all 4 batteries at the same time?

  Yes! The included 4-in-1 USB-C cable charges all 4 batteries at once from one port — unlike many others that only charge 2 at a time. ENEGON saves you time and needs just one charger.

• Are these compatible with Maglite D-cell flashlights?

  Yes! ENEGON D batteries are standard LR20 size, fitting all D-cell devices including Maglite. The constant 1.5V output keeps your flashlight at full brightness until only 15% capacity remains — unlike alkaline batteries that dim gradually.

• How do I know when charging is complete?

  When charging, the LED indicator light on each battery flashes. Once fully charged, the light turns steady (stops flashing)，Check level anytime: tap the touch sensor — 4 bars show charge: 4 bars = 100%, 3 = 75%, 2 = 50%, 1 = 15% (recharge soon).
