Ultra-slim 10000 mAh power bank

The Gigastone PB-7510 is a lithium-polymer power bank with a 10000 mAh capacity and a 0.4 inch profile. It provides two USB outputs, a standard USB-A port and a USB-C port, allowing simultaneous charging of two devices. The unit weighs 500 g and measures 9 x 3.5 x 3.3 cm.

Travellers needing quick top-ups.

This bank suits travellers who want a thin, pocketable pack that can recharge a smartphone two to three times and supports Qualcomm Quick Charge 3.0 at 18 W from the USB-A port. Buyers who need to power laptops or devices requiring higher-voltage USB-C Power Delivery should look elsewhere, as the USB-C output is limited to 5 V at 3 A.

18 W Qualcomm Quick Charge 3.0 on USB-A

The single specification that decides suitability is the 18 W maximum output delivered through the USB-A port via Qualcomm Quick Charge 3.0 at 5 V/3 A or 9 V/2 A. If your phone or accessory supports this protocol you will see the fastest recharge speeds this bank can provide; without it the output falls back to standard 5 V rates.

Questions about this item

Is the 10000 mAh capacity enough for several phone charges?

The 10000 mAh lithium polymer battery can charge a typical smartphone two to three times before the power bank itself needs recharging.

What does the 18 W maximum power rating mean when I plug in my phone?

It enables Qualcomm Quick Charge 3.0 at up to 9 V/2 A on the USB-A port and 5 V/3 A on the USB-C port, so compatible devices charge at their fastest supported speed.

How fast can I refill the power bank through the USB-C or micro USB input?

Micro USB accepts up to 9 V/2 A for an 18 W refill, while USB-C input takes 5 V/2 A; a full recharge can be as quick as three hours.
