while in this case, i will suggest a power bank ---but named UPS。
normally you can buy a lot from amazon or ebay.
it works like this:
main power grid--UPS---your hifi system.
and if the main power grid failes. your UPS will supply power (to you hifi system) using its internal batteries which storages electricity.
you can then turn off your hifh system before the UPS's batteries runs out.
