Flexopower LITHIUM700-SB50 Power Station

Short Summary

The Flexopower LITHIUM700-SB50 Portable Power Station is a rugged, travel-ready backup and off-grid power solution for clients who need reliable AC and DC power at camp, during load shedding, or on the road. With a 672Wh LiFePO4 battery, 700W pure sine wave AC output, true UPS capability, solar charging support, and an added Anderson SB50 grey DC output, it is built for practical use in South African homes, caravans, trailers, and overlanding setups.

Why This Product

When clients need portable power, they are often trying to solve two problems at once: dependable backup during outages and flexible power for camping or mobile work. Many power stations offer useful features, but not all are built for rugged use, DC-heavy applications, or long-term serviceability.

The LITHIUM700-SB50 helps solve that with a durable aluminium shell, replaceable LiFePO4 battery design, true UPS functionality, and a practical mix of AC, DC, USB, and solar charging options. For clients who want a tougher, longer-term power solution for load shedding, camping, caravans, and off-grid use, this unit offers strong everyday flexibility with less compromise.
