A lot of the newer portable chargers come with cables embedded in their cases. I I really like that concept because I have several different devices that use different connecting tips. My newer iPhone uses USB-C, an older iPad wants a Lightning tip and a flashlight and other gadgets require a micro-USB cable.The Charmast charger can service all three plus a couple more using the charger's two USB-A ports and an in/out USB-C socket. It turns into a real octopus of a charger.
In my tests the Charmast refueled four different devices in a little over an hour. The charger is rated at 10,000mAh. That makes it the equivalent of the AC powered chargers I keep on my desk and significantly more powerful than any of the portable chargers I've acquired over the past couple of years.
The only minor concern that I have about the Charmast power bank (other than the pink color) is the several hours it requires to recharge itself. My advice is to plan to recharge it overnight.
