1) Do the math, seriously without knowing what you need you don't know what to shop for.
2) Assume the claimed specs are enthusiastic. Actuals will almost certainly be worse. Factor in a margin to account for this.
3) sort out the charging infrastructure you need. A higher end powerbank, may allow simultaneous charge and discharge (which may be useful) and has all the charging controls built in, such that the charger is just a voltage source. A connectorized lithium battery requires a charger that does the charging control. Lithium cells are very different than lead acid and require smarter chargers.
Alternatively buy random battery packs or power banks and try them.
