Nice little power package,
This review is from: AmazonBasics 175-Watt Pocket Power Inverter with 2.1 Amp USB Port to Charge iPad, Kindle, and Other Electronics (Electronics)
Vine Customer Review of Free Product (What's this?)
In the limited time I have had the inverter my first impressions are favorable although the listed load capacity of 175w may be a bit misleading.
My primary intended use is to provide on the go charge capability for a laptop that draws approximately 65w continuous power, well within the inverter's recommended range of not more than 120w when plugged a cigarette type 12v outlet. In instances where required power is more than 120w but not to exceed 130w continuous, the inverter should be clamped to vehicle battery terminals with the included clips. The upward range of 175w refers to the device's maximum supportable load for no more than 5 seconds in peak load situations. Use for a device, or combination of devices, surpassing 130w is not recommended.
This slim form device features one AC port and one USB port, a built-in cooling fan, 12v adapter cord and a battery clip cable but does not have a separate on/off switch. The fan is rather loud and seems to be engaged as soon as the device is attached to a power source. At this point I cannot address long term reliability however I did notice the unit tends to heat up pretty quickly (the manual also indicates unit temperatures can reach 158 degrees Fahrenheit) although thus far neither the auto cutoff feature nor low voltage indicator lights have been activated during my use.
It will support simultaneous power/charging of one USB and one AC device as long as the 130w maximum load continuous threshold is not exceeded. It is projected the inverter can be used for up to 2.5 hours before full depletion of a vehicle's battery charge is likely. Obviously, projected time will vary based on other factors like age, condition and existing charge of the battery itself.
The manual further advises caution should be taken when using the inverter when cranking a vehicle's engine as the increase power required may negatively impact powering and charging.
