The Lipower PA300 delivers 252Wh of its 296Wh rated capacity, an 85% result, compared to a 300W pure sine inverter. Charging is 45W, the slowest we have recorded, taking about 6.5 hours. Mid-range price tier.
My Quick Verdict
Forty-five watts is the lowest charging input we have recorded on any unit at any capacity. Filling the 296Wh pack takes around six and a half hours.
To put that in context, our charging data indicate a median of 62 watts for this capacity class, which is already slow. The PA300 is well below even that.
What the unit gets right, it gets properly right. Eighty-five percent conversion, correct 120 volt pure sine output under 2% distortion, 1.6% idle drain, and 45 decibels are all sound results.
An integrated LED light bar with SOS modes is a sensible touch for an emergency or camping unit.
Best for: Emergency kits charged once and stored, where recharge speed genuinely never matters.
Not for: Anyone who needs the unit back quickly, or who charges from solar.
