Suited for daily business mobility.

Buyers who want more storage capacity for all-day use away from mains power should look at higher-capacity alternatives. The lithium-polymer chemistry and built-in protection support safe operation in typical business environments.

Steady output during sustained workloads

OEM-grade cells maintain stable voltage through long document editing, video calls and light development sessions without sudden drops. Integrated safeguards prevent over-charging, over-discharging, overheating and short-circuit conditions during continuous operation. The 50Wh rating supports consistent runtime for typical productivity workloads rather than short bursts.
