It might be worth looking for one that charges (itself) up via USB C, which will be much faster. My latest purchase has both USB C and the usual little USB port, alongside the two normal USB ports for plugging devices in.
Not had it long, but seems to be fine - 10,000 mAh, Jonkuu branded, £11, about the size of a packet of cigarettes, if anyone remembers what those were.
There's a size / capacity payoff. You can get lipstick sized ones, but you'll get fewer charges.
