The QMADIX portable 5000mAh power bank is so small and lightweight that it can be carried around very easily, either in your pocket, a bag, or even in your hand. The lightning-input connector allows for a quick and safe charging experience for any Apple device. With the built-in USB-A and Lightning cables, you won’t have to worry about carrying cords around with you. The easy-to-access cables offer a great design for the unit. Just pull the built-in cable out, connect it and you’re good to go.

Charging technology

Devices can be charged fully at least one time.

QMADIX Keychain Power Bank


The built-in USB cables provide power to your power bank and any Apple device. You will need to use the USB-A cable to recharge the power bank’s lithium-ion battery and the lightning cable to provide power to your Apple device.

Regarding its technical specifications, This power bank has 5V/1A for the input and 5V/1A for the output. Despite the company’s claim that it can fast-charge any Apple device, the reality is that it powers up the iPhone 11 in around 3 hours, the same time if the 5WApple charger is used. However, it takes the power bank up to 6 hours to recharge fully, which is a long time considering its relatively small capacity.


This power bank by QMADIX measures 7.6 x 3.8 x 1.5 inches and weighs just 6.4 ounces, which is small and light enough to fit perfectly into the palm of your hand or into your back pocket. The small size also makes it ideal for traveling, allowing you to conveniently charge your Apple devices anytime and anywhere.

You shouldn’t have any trouble taking this device aboard with you on a flight since it only has 19Wh, which is way below the 100Wh limit stipulated by the TSA.

Compared to other products, the QMADIX keychain power bank distinguishes itself by its compact size. The metallic clip allows it to be easily attached to all sorts of items such as backpacks, trousers, belts, pouches, etc.

Look and feel

This slim power bank is so small that it can easily save space. With its minimal design, it’s very easy to see why it’s not as bulky or heavy as other chargers. You can only purchase the device in one color, black. The smooth surface gives it a nice appearance that has a rubber-like texture, making it very easy to hold onto.

There are four LED indicators on the top of the device that let you know how much power is left and indicates the charging status of the power bank. It also has a power button next to the LED lights, so you can turn the device on to charge your smartphone, tablets or even iPod just by pressing it.

The device also has two USB cables built-in, USB-A and Lightning cable. USB-A cable is solely intended to charge the power bank. On the other hand, the Lightning cable charges any Apple device, so there is less hassle to use separate cables that you may have forgotten about or are missing. When the cables aren’t being used, they will clip to the power bank. The cords are three inches long each when they’re in use and they don’t extend and/or retract.
