Previous deal https://www.ozbargain.com.au/node/871249 had comments saying that since this isn't pure sine wave it's not the best for running appliances off. Good for utilizing those EGO batteries for charging USB devices during a blackout though.
$130 off the 150 Watt Inverter Kit. Basically a free inverter and charger for less than the regular price of the (overpriced) battery. I bought one last time at $229 but haven't used the inverter. The battery was manufactured 10-2021 so they (EGO or Distributors) may be clearing out old stock or getting ready to delete in favour of the 180W version?
EGO 56V 2.5Ah Nexus Escape 150-Watt Power Inverter Kit - PAD1501E
There are also 180W and 400W versions both with pure sine wave and built in LEDs but they aren't currently on sale.
The 180W is newer and much more capable than the 150W and retails for $349 in kit form https://www.tradetools.com/ego-56v-2-5ah-nexus-escape-180-wa… or skin for $169 https://www.tradetools.com/ego-56v-nexus-escape-180-watt-pow…
