Cheap power inverter over priced
||Posted . Owned for 3 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Does not last long and is cheap. If your not using it for anything that can pull power you should be good. Its great for charging phones but thats it.

Wires to small makes no sense to cost 65 dollars
||Posted . Owned for 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The wires are way too small. Good luck! If you're trying to run this into your cabin from your battery, they're like 2 to 5 inches

No, I would not recommend this to a friendCobra needs to stick to radar detectors
||Posted . Owned for 4 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I purchased this to use while on the road traveling for sales to charge my MS Surface. When plugged into the cig lighter your supposed to get 120 but everytime i would plug in my surface charger it would run for maybe 5 minutes before throwing this obnoxiously loud error buzzer. I tried two different chargers, one travel & the standard docking type, both did the same. The cable is extremely short as well. I dont know where they exepct you to mount this and not stress the cable or be able to route it anywhere hidden. Returned & will be trying a different brand.

Posted .We’re sorry to hear about your experience. Some vehicle power outlets may not provide enough consistent power for certain laptop chargers, which can cause the inverter’s protection alarm to activate. You could also connect directly to the battery with the provided cables. We appreciate your feedback regarding the cable length as well and will be sure to share it with our team.
