Technology / US catalogue
Compare output limits, backed outlets, replacement batteries and manufacturer runtime estimates at the same stated load.
US 120 V desktop AC UPS units. DC mini-UPS devices, portable power stations and rack installations are outside this category. Runtime estimates do not establish installed runtime or successful NAS shutdown; check the exact hardware revision, load and communication path.
Specifications come from the linked manufacturer documents and seller listings. We have not independently tested these products.
Add the actual load of the NAS, router, switch and other backed equipment. Compare documented estimates at the same load, leave time for shutdown and account for battery age and charge. VA and watts are separate output limits, not runtime.
A USB monitoring connection is separate from USB charging. Check the exact NAS model and software, connect the data cable, and keep required network equipment powered for network clients. Vendor recommendations and historical driver reports are not an outage and restart test of your installation.
Match the US voltage, output rating, outlet layout and exact purchase option. A reused model name can span different hardware; battery replacement may depend on the serial prefix on the delivered unit.
