Bests & Worsts Reviews from Amazon

Can't beat the price for a pre-packaged 220 watt hour lithium battery with sine wave inverter. However, it has many technical quirks that they leave out of the description. Any reference to 'solar' input below is based off the combined use of the Suaoki 60W Portable Sunpower Folding Solar Panel. - Inverter and USB ports cannot be run off solar input. Only the DC outputs function. This was very disappointing for my desired use case. - The LED charge indicator lights do very odd things while on solar input. (Sometimes they marquee indicating charging, sometimes they all light up and stay solid even though the battery is not fully charged, sometimes the marquee seems to indicate the level of energy coming from solar input but I am not 100% sure that is a real feature. At least the unit seems to charge regardless of the behavior of the LED lights. (I am revising this section and raising my review 1 star) - (The DC outputs are always live regardless of power switch state and DC charge/discharge) There is a single power switch for the AC inverter and USB ports. This means you are always energizing the inverter when using the USB ports. I was unable to get an answer as to how much energy loss this represents but I would think it's in the neighborhood of 4-5watts. Unfortunately, this burns stored energy needlessly when not using the inverter output. (since I was unable to get a technical response from Suaoki there may be an auto on/off mechanism for the inverter that is not advertised. Since I didn't receive an answer I will have to assume it wastes energy) Note: I was never able to get a response to any technical questions sent to Suaoki via Amazon or their support email address listed on their website.
