Smart Charging Technology
Understanding QC3.0/PD3.0 Fast Charging
With standard 5V USB sources: When using regular USB wall adapters or computer ports, the PB2S charges one battery at 2A, or splits power to 1A per battery when charging two batteries.
With QC3.0/PD3.0 fast chargers: The PB2S automatically detects compatible fast charging adapters and increases charging voltage to 9V/2A or 12V/1.5A, charging both batteries at full 2A speed simultaneously. We recommend adding the optional QC3.0 Wall Adapter available above the "Add to Cart" button for maximum charging performance.
Practical Power Bank Features

- Multiple protection systems for safe charging
Smart Ways and Ideas to Use Your New Power Bank Charger Combo
✔ Emergency Preparedness
During power outages, use Orbtronic batteries in the PB2S to charge phones and essential devices, then use those same batteries in flashlights when darkness falls. Stock up on several batteries for continuous power that outlasts any standard power bank.
✔ Outdoor Adventures
For camping or hiking, pack the PB2S with Orbtronic batteries to charge GPS devices, phones, and headlamps without adding significant weight. Bring spare batteries instead of multiple bulky power banks.
✔ Travel Companion
For air travel, carry the PB2S with several fully charged batteries (all TSA-compliant) for 3-4 times the power capacity of standard power banks at half the weight. Perfect for long flights and destinations with limited power access.
✔ Daily Convenience
For commutes and everyday use, keep fresh batteries ready to swap when needed instead of waiting hours for traditional power banks to recharge. Never be caught without power again.
