Got Questions About SlimVolt™?

Should I get a 5,000mAh or 10,000mAh power bank?

If you want something ultra-light for quick top-ups and portability, go for the 5,000mAh model.

For multiple full charges or powering more than one device, the 10,000mAh is your go-to. Both options are ultra-slim and travel-ready.

Can I bring a 10,000mAh power bank on board?

Yes! Both 5,000mAh and 10,000mAh SlimVolt™ power banks are TSA-approved for carry-on luggage. They’re under the airline limit and safe for travel worldwide.

How long does a power bank last?

On average, SlimVolt™ power banks hold 500+ full charge cycles. That means over a year of daily use — and even longer with moderate use. Built to last.

How do you charge a power bank?

Just plug it into a wall adapter or USB-C charger. SlimVolt™ supports PD fast charging, so it refuels in half the time compared to older models.

What does GaN mean on a charger?

GaN (Gallium Nitride) chargers are smaller, cooler, and more efficient than traditional ones. And SlimVolt™ works perfectly with any USB-C PD GaN charger.

Are all USB-C cables the same?

No. Some only support slow charging or limited data transfer. For best results, use a high-quality USB-C PD cable — SlimVolt™ includes one that’s optimized for fast charging.

Is wireless charging safe for my phone?

Absolutely. SlimVolt™ uses smart safety chips to regulate temperature and prevent overcharging. It’s designed to protect your phone while delivering consistent magnetic power.

Can I use a wireless charger with any phone?

As long as your phone supports Qi or MagSafe wireless charging, it will work with SlimVolt™. iPhones and many Android models are fully compatible.

Can I use car chargers for my SlimVolt™?

Yes — just make sure your car charger supports USB-C PD (Power Delivery) for fast input. This helps SlimVolt™ recharge quickly even while you’re on the road.

How is a 30W car charger different from a 120W one?

Wattage affects how fast devices charge.

  • A 30W charger is great for SlimVolt™ and phones.
  • A 120W charger is better suited for larger devices like laptops or when charging multiple devices at once.

SlimVolt™ works with both — just use a PD-enabled port for best performance.

How long does shipping take?

5–8 business days in the US and EU. International shipping applies for at most 15 days
