I’ve looked at a few chargers and they don’t seem to have wattage ratings - I see listings like this: 20000mAh
I saw one that had several photos of the item and in one of the photos it said “Triple-device charging - 30W of power ensures high-speed multi-device charging.” This item was rated at 26800mAh A quick google search tells me mAh stands for milli Ampere hour which is a measure of the battery’s energy storage capacity. The higher the mAh rating the more energy it can store. Nowhere else in the description of the item did it mentioned wattage. I looked up the syncwire charger you mentioned and I think I will get one but my original question is about portable batteries that will charge your device when on the go like on a long flight when your iPad is running out of battery power and there is not electrical outlet to charge the device.
