Battery Backup for Computer

Battery backup for a computer is a different product from battery backup for a router, and confusing the two is a common buying mistake. A desktop computer draws far more power than a router: the computer itself, its monitor, and its peripherals together draw several times what a small network device draws, and a battery sized for a router cannot carry that load for any useful time. This page states that boundary directly, because a buyer who buys a mini UPS for a computer will discover the mismatch at the first cut.

The computer case has its own requirements. The UPS must output mains voltage, because computers run on mains power through their own supplies, and it must deliver enough power for the computer and monitor together, with a battery large enough to bridge the cut or to allow an orderly shutdown. Those are the requirements of a general computer UPS, which is a larger product class than the mini UPS range on this site, and this site does not present mini UPS units as a substitute for it.

There is one overlap worth noting: the network side of a computer setup. A computer that survives a cut on a computer UPS still loses its network if the router and modem lose power, so a complete computer backup arrangement includes both a computer UPS for the computer and a mini UPS for the network chain. Buyers planning computer backup should therefore plan two products, not one, and should state both loads in the inquiry so the arrangement can be confirmed as a whole.

Small computing devices sit in between. A small single-board computer, a thin client, or a small network storage device draws closer to a router than to a desktop, and may suit a mini UPS, provided its voltage and draw are checked against the output as the voltage and current guides explain. The boundary is the load, not the device name, and the label figures decide in every case.

For a confirmed arrangement, state the computer, the monitor, the network chain, and the required bridge time in the inquiry. Minimum order quantity is confirmed per order, customisation can be discussed, certificates are available upon request, and delivery time is not published. The company contact is Ms. Zita Huang.
