My speaker is currently at work so I cannot check the power adapter but the manual suggests 12v @ 2A. However Im pretty sure it is 18V.

Anyway, would the powerbank be able to power the speaker and how long is it likely to last before it runs out of battery?

Power requirement: Input: 100V – 240V 50/60Hz;

Output: 12V 2A

Doubt it. It needs 100v-240v supply.

Please note that there is conversion Rate with the power bank, which usually is 85%. When you charger your laptop with 19v input, the built-in 3.7v battery needs to be boosted to 19v. According to energy conservation law, the input capacity should be: (3.7V * 28000mah)* 85% /19V, about 4700mah.

Looks like they're saying it's got a 90Wh capacity in practice.

We don't know the speaker power consumption and it'll likely vary by output volume anyway but if we take the maximum 24W then that's 3 hours, 45 minutes.

It could go either side, I'd expect 3 hours as worst case if they're exaggerating the efficiency/capacity but you might get as much as six or seven hours if the speaker is a lot lower than it's maximum power.
