Not the smallest or fastest at this capacity, but not a bad price at this capacity for one of the few easy to find 3C rated power banks (which you'll need if you plan to travel with it in China)

Is there an option for fast charging and slow charging? I keep hearing that slow charging will save your battery from early death.

HTX Studio did a really good YT video on how fast charging affects phones. Definitely worth checking out

All lithium batteries fair better when charged slowly, so if you charge it with a lower wattage charger that should help extend its life. Another factor that impacts battery health is keeping your battery close to 100% charged. When the cathode is near its highest potential (100% charge), the battery chemistry begins to degrade and you get things like lithium metal deposition and other forms of breakdown. Who knows where the sweet spot is in balancing caring for your battery and getting good value out of it. I generally turn on battery protection on my phones when I'm in town, off when I'm traveling further.

All of this advice above will help preserve your battery life and reduce degradation over time. Similar to charging your battery to near capacity (100%), discharging your battery below 20% will damage the battery (especially bad as you near complete discharge (0%)), with the same types of cathode cracking and lithium deposit buildup increasing internal resistance, which (over time) leads to permanent capacity loss. I do the exact same thing, enabling battery protection for my normal close-to-home days, and turning it off when traveling to get extra battery life.

Disable fast charging on your tablet or phone.
