Aye and that’s only the peak, usually it hovers between 12-15W. The XTPower has an integrated display, showing the current draw. Additional info for anyone interested: > [@I installed a battery numark mixstream pro](https://community.enginedj.com/t/i-installed-a-battery-numark-mixstream-pro/43202/37): > > The Go lasts between 3.5-4.5hrs, but not longer. The Mixstream Pro together with my suggested powerbank easily reaches 5-6 hrs, plus you have the larger jogwheels, separate VU ch-meter mode, integrated speakers and an overall lower price. Not to mention, you can easily replace the power source anytime. Or add a second one for some lights. The smaller XT-16000QC3 already has 57Whr which is plenty, but if you need even more, its bigger brother has 73Whr (lasting 7-8hrs with the Mixstream) while … Your solution also works, since the power draw is pretty low, but in general I recommend avoiding 5V-\>12V converter cables and rather go for powerbanks which have an 12V option directly integrated, allowing you to push way more Ampere or at least have the reserves for that. --- _[View the full topic](https://community.enginedj.com/t/need-a-generator-for-prime-4-and-small-bookshelf-speakers/47512)._
