Questions & answers
How many times will it charge my phone?

Using a charging cable, you can get about 4 full charges for an iPhone 16 or 16 Pro, or about 2 full charges, plus a 90% top-up for a Samsung Galaxy S24 Ultra or S25 Ultra. Using your phone while it charges will reduce these amounts. Wireless charging will give you fewer charges.

Which phones does it work with?

It charges iPhones, Samsung Galaxy phones and other Android phones using the right cable. The wireless pad works only with phones that support Qi wireless charging. These are examples, not a complete list.

Will it work with my phone case?

It's designed for smooth, thin cases — not rugged or textured ones, which can block the suction cups and wireless charging.

Can I use my phone while it charges?

Yes — the suction cups hold it in place so you can use it hands-free.

Why is this power bank charging my phone slowly?

Try charging your phone on its own with a cable that supports fast charging. Charging can slow down if you are using the phone, it feels warm, or its battery is nearly full. Your phone also decides how much power it can take.

How many times will it charge my iPad?

For an iPad (A16) or an 11-inch iPad Air (M3), expect about 1 full charge, plus a 90% top-up using a charging cable. Other iPads may get more or fewer charges depending on their battery size. Using the iPad while it charges will reduce the amount.

Why is my power bank taking a long time to recharge?

The wall charger or cable may be slowing it down. Try another compatible cable and plug it into a wall charger rather than a computer. We do not yet have a confirmed full-charge time for this model.

What is the difference between 20,000mAh and 30,000mAh power banks?

A 30,000mAh power bank stores 50% more power than a 20,000mAh model, so it can keep your devices going longer. It does not automatically charge them faster. This model is 20,000mAh. Compare the size, weight and charging speed before choosing.

Can I charge a device while recharging the power bank?

Yes. You can plug the power bank into a wall charger and charge your device from the power bank at the same time. Charging both at once may take longer.

Why does wireless charging stop or fail to start?

Move your phone until it lines up with the charging pad. Remove any wallet, cards or metal attachments, and try taking the case off. If the phone feels warm, let it cool down. Your phone must support wireless charging.
