Built for Safety and Quality

Safety is non-negotiable with electronics. Our power banks are rigorously tested to keep devices—and users—safe:

  • A-grade lithium polymer batteries with 300 recharge cycles.
  • 60-degree temperature cutoff to prevent overheating.
  • Premium circuit boards and metallic components for reliability.
  • Internal sensors monitor pressure, amplitude, and temperature.
  • Onsite inspections ensure top-notch manufacturing.

Certified and trusted, our power banks deliver peace of mind alongside power. Learn more about our quality standards on our page.

Cheap wholesale pricing starts at just $5 per unit for large orders, and it includes full branding with no hidden fees (GST excluded for transparency). Found a better deal?

Universal USB Connections

Our power banks come with industry-standard USB ports:

  • Type A USB Output: Single and Dual outputs available on selected styles
  • Type C USB Output: High-speed charging for modern devices.
  • Lightning Connectors: Optional for Apple users, built-in or as add-on cables.

Mix and match cables to suit your audience—ask us about extras when ordering.

What are the pros of high-capacity vs slim power banks?

Both types are popular, but they suit different needs:

  • High-capacity power banks: These can recharge phones multiple times and often include multiple ports. They are valued as long-lasting gifts, making them ideal for corporate clients, staff packs, or premium promotions.

  • Slim power banks: These are compact, lightweight, and cost-effective. They usually provide a single full charge, which makes them well-suited to large giveaways, trade shows, or events where portability is important.

Case Study: Massey University
