If I can make a recommendation... the Iniu 65W 25000mah powerbank on Amazon. There's a 50% coupon every 2-3 weeks so it is $30. Just need to keep an eye on it.
It is the only powerbank I ever had out of which I get >90% of the advertised capacity. (Advertised: 92.5Wh, measured: 102Wh in, 84Wh out.)
