Flexopower LITHIUM555 Portable Power Station


SKU: SL0223 Categories: ,



The Lithium555 by Flexopower is the first power station of its kind with a replaceable Lithium battery. At the end of the battery service life, replace battery only and continue using it. 

Service life of battery is nominal 500 cycles, after which the capacity is still at >90%. Replacement should only be necessary after 1200+ cycles.

Being able to replace only the battery, your cost of ownership drops significantly, making it the most affordable quality product in the market. – Competitor products, even at a lower purchase cost, will end up costing more, because they are total replacement only. 

Only 2h re-charge time after a 2h load shedding period (typical user experience, can vary).

Housing built with heavy duty Aluminium extrusion. SA plugs.

Perfect for multiple use: take it camping to run your 12V camping fridge, re-charge the smart phone, camera, laptop etc..

  • Lithium battery: Quality Lithium battery in 4 series configuration. 555Wh / 150.000mAh capacity.
