I missed the boat on the giveaway, but glad to hear Anker is welcoming input.
I haven't found a reliable, small, 12VDC to 120VAC inverter that meets my needs for an automobile yet.
The BESTEK 150W Power Inverter looks good form factor wise, but I wouldn't trust their USB charging ports to quickly charge a smartphone or tablet.
Here's what I've been looking for:
* around 100W-200W output power (10A*12V=120W, some car DC outlets may be fused at 15A*14.7V=220W)
* connected to the DC outlet via a cable rather than a monolithic fat plastic or metal housing
* must be able to be stored in glovebox or center console when not in use. Somewhere between a deck of cards and the PowerPort 10. The PowerPort 5 is a great size. Thinner is better, as then it would be able to hide between the passenger seat and center console.
* ideally fanless, but a quiet fan is acceptable.
* should be cool to the touch and silent when under no load
* should be cool or warm to the touch and quiet when under load (especially under light load)
* should not emit any sound (several of my mains-to-USB chargers emit very-high-pitched whines)
* one AC mains ports.
* at least one 2A+ USB-A port, preferably two 2.4A USB-A ports (24W) with PowerIQ and/or QC2.0+.
* optionally one or two 3A+ USB-C port.
* max power should be able to be drawn from all USB ports simultaneously
* intelligently handle over-current, over-voltage, and under-voltage conditions, as well as handle over and under temperature conditions.
* If it's meaningful, some visual indication if the inverter is operating at 100% or is limiting any of the outputs.
* Don't blow the car's fuse to the DC socket.
* intelligently balance power between USB ports and AC
Will Anker be releasing more inverters after the recent release of the PowerHouse?
