Do you need a cable to charge a power bank?
As such, you must carry an extra cable to charge the power bank itself. Sanag’s portable charger is a power bank, a charging adapter, and a wireless charger, all wrapped in one, making it the perfect travel companion. The portable charger ships with a 10,000mAh battery, which should suffice for most users.
What is a power bank?
A slew of terms are used to describe power banks, including portable batteries, portable chargers, external battery packs and even, somewhat confusingly, USB chargers, which is what wall chargers are often called.
How many devices can a power bank charge?
The icing on the cake is that the power bank recharges continuously under the sun, so you can top up your smartphone and other accessories during emergencies. Along with the built-in cable, the power bank comes with two USB-A output ports and a USB-C output port. As a result, you can charge up to seven devices simultaneously.
How much battery does a power bank charge?
The power bank features a 5,000mAh battery, which can top up your iPhone’s battery by up to 50-60 percent, depending on the make and model of your smartphone. A slight inconvenience, though, is that the power bank itself charges via USB-C. So, if you’re primarily an iPhone user, you must carry an additional cable.
What is the difference between a power bank and a wireless charger?
Fast and Safe Charging: Featuring advanced charging technologies, the power bank delivers up to 20W PD USB-C fast charging, while the 3-in-1 wireless charger provides 15W wireless charging with overcharge and overheating protection.
How does the sanag power bank work?
In addition to the built-in cables, the USB-A and USB-C ports onboard can charge external devices. Notably, the Sanag power bank directly plugs into a wall outlet, so you don’t need a cable to charge the power bank. What’s more, the power bank’s shell also doubles up as a wireless charger.
