Power banks are one of the most popular promotional tech gifts in Australia. They easily charge phones, tables and certain models even charge laptops. They’re practical, obvious, and perfect for conferences, staff onboarding kits, and client gifts. But with your Logo on the product, safety is non-negotiable. A faulty powerbank can overheat, damage devices, or create negative brand associations.
Here’s a step-by-step guide to identifying safe, reliable promotional power banks before committing to a bulk order.
1. Confirm Battery Cell Quality
The battery is the most crucial component inside a power bank.
- Check the spec sheet — look for Lithium-Polymer or A-grade Lithium-Ion cells.
- Ask your supplier whether the cells are new and certified (not recycled). Yes! All power banks in our range are new and certified.
- Avoid cheap imports with no information on cell grade — this is often where corners are cut.
A-grade cells last longer, hold charge better, and are less prone to swelling or failure.
2. Look for Smart Safety Circuitry
A quality powerbank regulates power flow, keeping both the unit and your devices safe.
Key protections to confirm:
- Overcharge and over-discharge
- Short-circuit sensors to cut power
- Temperature sensors to cut power
- Surge and overcurrent protection
These features are usually listed in the product description. If they’re not, ask your supplier directly.
3. Verify Certifications
Compliance is essential for peace of mind.
- RCM (Regulatory Compliance Mark) — mandatory for electrical products sold in Australia
- CE, RoHS, FCC — international standards that indicate quality and safety
- Request a certificate of conformity or test report — reputable suppliers keep these ready for clients
The presence of these marks on the device or packaging is a quick visual confirmation of compliance.
4. Inspect Build and Finish
Physical construction says a lot about internal quality.
- Shake gently — there should be no rattles
- Check the casing — strong ABS plastic or aluminium is ideal. Please give it a squeeze or a press.
- Test ports — cables should fit firmly (but not excessively tight) without wobble
- Look for smooth edges and consistent seams
A solid, well-finished powerbank feels professional and reflects well on your brand.
5. Ask About Warranty and QC
Trusted suppliers back their products.
- Confirm there is a warranty period — 12 months is common
- Ask whether batches are tested before shipping. (Yes, all Cubic Promote power banks have undergone batch testing)
- Choose a supplier that can provide documentation and after-sales support
6. Reality-Check the Specs
Capacity numbers should match the size and weight of the device.
- If a tiny powerbank claims 20,000 mAh, it’s likely overstated
- Test a sample — monitor how warm it gets while charging
- Check that the LED indicators work consistently and match the listed capacity
These small checks help ensure the product performs as expected before you invest in branding and bulk production.
Putting your Logo on a power bank
Safe power banks protect your recipients’ devices and your brand reputation. By checking battery cell quality, built-in circuitry, certifications, build integrity, and supplier credibility, you can confidently put your Logo on a product that people will trust and use.
