Volt Matrix 20K™ — Slim 20,000mAh Fast-Charge Power Bank
$39.99
Power that outlasts your itinerary
The Matrix 20K is built for travelers who can't afford a dead phone at the gate, on the trail, or three trains from the hotel. A full 20,000mAh reserve keeps your phone, earbuds, and watch going for days, not hours, yet the casing stays slim enough to disappear into a carry-on pocket.
- Multi-day capacity — enough charge to refill a typical phone several times over before the bank itself needs a top-up.
- USB-C fast charging — Power Delivery tops up modern phones dramatically faster than a standard cable, and refills the bank quickly between legs of a trip.
- Two devices at once — charge phone and earbuds together, so you're never choosing what stays alive.
- Cabin-friendly — slim, lightweight, and within airline carry-on limits for lithium power banks (keep it in your carry-on, never checked).

Frequently Asked Questions
Straight answers, sourced from our store policies.
How much does shipping cost?
Standard U.S. shipping is $5.99 and takes 5–7 business days. Orders over $75 (before tax) ship free within the contiguous United States — applied automatically at checkout, no code needed.
When will my order ship?
Orders are typically processed within 1–3 business days (Monday–Friday); orders placed on weekends or holidays are processed the next business day. You'll receive a confirmation email right away and a second email with your tracking number as soon as your order ships.
What is your return policy?
You have 30 days from delivery to request a return. Items must be unused, in original condition, and in their original packaging. Email store@wbtravelpros.com or call 800-211-3161 to start a return. Once we receive and inspect your return, approved refunds are processed to your original payment method within 3–5 business days — your bank may take a few additional days to post it. Final Sale items and gift cards can't be returned.
How do I track my order?
Your shipping confirmation email includes a tracking number and a direct tracking link. You can also use our Track My Order page any time with your order number and email address.
My order arrived damaged — what now?
Contact us within 7 days of delivery — sooner is always better — at store@wbtravelpros.com with your order number and photos of the issue. We'll send a replacement or issue a full refund promptly; in most cases you won't need to return the damaged item.
