Internet backup power

Keep network equipment powered during a brownout.

Choose the networking equipment that must stay powered. Estimate battery capacity from watts and hours, then check the connections and the provider’s network too.

Selecting a device replaces the wattage. Add the remaining network devices to the total yourself.

Connection path

DC is suitable only when voltage, polarity, connector and equipment requirements match exactly.

Edition market

Calculated against documented EcoFlow South Africa models. Sufficient capacity does not prove connection compatibility or uninterrupted operation during load-shedding.

Battery target with reserve

576 Wh

Your network: 32 W · 12 hours
Calculated before reserve: 480 Wh
Additional reserve: 20%

Compare documented models

This is an energy estimate. Test transfer and idle shutdown; the provider’s equipment must also remain available.

A power station may suit this longer duration.

A cold or older battery can supply less energy.

Cold and battery ageing

The estimate uses the battery data and calculation assumptions shown with this result. That is not a measurement of the battery’s current condition. Cold and battery ageing are not calculated separately.

Cold is not the same as wear. Cold can temporarily limit the available energy and the power that can be delivered. Ageing can permanently reduce the storage capacity, even when the screen shows ‘100% charged’.

Follow the temperature limits for charging and using from the manual of your model. Check important applications with your own setup.

More about our battery assumptions

Compare, then check the connection

Compare regional specifications with the battery target.

These models have documented regional specifications. A capacity calculation does not prove uninterrupted operation or connection compatibility. A dedicated router UPS may be more practical for a small load.

South African model checks remain open. Use the calculated energy target, then verify DC voltage, polarity, connector and switchover behaviour on the exact equipment. For current load-shedding information see Eskom load shedding. Compare EcoFlow South Africa records →

Energy and continuous-power comparison from EcoFlow South Africa product pages. Stock, price, warranty, delivered SKU and socket compatibility are separate checks. Official EcoFlow South Africa gallery model illustration. Where sockets are visible, the artwork shows South African three-round-pin (Type M-style) and two-pin sockets. Gallery images do not prove the sockets, lead or hardware revision of a delivered unit. The 1600 W surge and X-Boost figures have no duration, so startup suitability is unconfirmed. The same page also lists a European Plug variant (unavailable on 5 October 2026); order the South African Plug variant. The AC outlet count is not given in the table.EcoFlow South Africa — model illustration ↗

A planning estimate, not a hands-on test. AC and DC efficiency factors are assumptions. Idle consumption, temperature, ageing and low-load shutdown may shorten runtime. Check the exact connections and test the complete setup.

Which boxes need power?

Choose the right type

Three ways to back up the connection.

The largest battery is not automatically the best choice. Consider the equipment, required duration and connections together.

COMPACT

DC mini-UPS

For a compatible router or modem with known voltage, polarity and connector requirements.

Can reduce conversion loss
Quiet and compact
Voltage must match exactly

Example: a few hours of network backup

ORIGINAL ADAPTERS

Conventional AC UPS

Use the original power adapters and check that the equipment tolerates the UPS transfer during an outage.

No special DC lead needed
Check modem, router and switch together
Check Wh as well as VA

Example: bridging a brief outage

LONGER DURATION

Power station

More energy for longer outages, satellite networking and laptops, though it may be larger than a router alone needs.

Longer runtime and several outputs
Can support other devices
Test transfer time and idle shutdown

Example: longer or multi-device backup

Test before relying on it

Check the complete chain.

01
Simulate an outage safely
Follow the equipment instructions to test transfer to backup and confirm that the modem, optical terminal, router and required mesh nodes stay online.
02
Wait for idle-shutdown timers
Some stations switch a small load off only after an idle timer expires.
03
Check with the provider
Ask whether the provider’s equipment outside your home has outage backup. Keep an alternative connection for important work.
04
Label every lead
Record DC voltage, current, polarity and connector. A matching shape alone proves nothing.
