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 |
