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
