Key Features (2025 Upgrade)

Dual-Task Power (Li-ion Exclusive)
- Charge 4 Li-ion batteries (e.g., 18650/21700) WHILE powering devices via USB (5V/2A).
- Current Options per Slot: 0.3A (eco) / 0.5A (standard) / 1.0A (fast).
Ni-MH Priority Safety
- Inserting any Ni-MH battery → Instantly disables USB output (screen shows ️ "NO USB").
- All slots charge at fixed 0.5A (no user setup needed).
24000mAh Power Bank
- With 4x LiitoKala King6000 (sold separately):
  - Output: 5V/2A max (compatible with phones/tablets).
  - Runtime: ≈6 full iPhone charges.

Scenario	Pro Tip
Maximizing Output	Use slots 1+2 for 1.0A charging + slots 3+4 for 0.5A → Free USB port for stable 2A output
Extending Battery Life	Charge small Li-ion (10440/14500) at 0.3A → Reduces heat + extends cycles by 2x
Emergency Prep	Keep 2x King6000 in slots 1-2 (1.0A) → Instant 12,000mAh backup + charge AAAs in slots 3-4
Avoiding Errors	Never mix Li-ion + Ni-MH → Insert Ni-MH first to auto-lock USB mode

Scenario		Benefit
Maximizing Output		25% faster device charging
Extending Battery Life		Save €50/year on replacements
Emergency Prep		Dual-device readiness
Avoiding Errors		Prevents system errors
