Choosing Your Ideal Power Bank
Ask these 3 questions before buying:
- How many devices need simultaneous charging?
- What's your typical outdoor exposure time?
- Do you need pass-through charging capability?
Pro Tip: Look for PD 3.0 (Power Delivery) certification for faster smartphone charging – it's like having a sports car engine in your power bank!
Why Two-Way Matters
Imagine this: You're camping with a drained power bank. With two-way functionality, you can:
- Recharge from a car outlet while charging your phone
- Swap energy between multiple power banks
