Review on GIANDEL 600W Pure Sine Wave Power Inverter 12V DC to 110V 120V - Remote Control, Dual AC Outlets, USB Port - Ideal for RVs, Cars, Solar Systems, Emergencies by Balakrishna Monzon

This is a tough buy if you use chargers and high power electronics on the inverter. I've scoured the web quite a bit for comments on other inverters and found that I need to choose a pure sine wave inverter for my use case. I'm charging a Stihl chainsaw battery and I have the fastest charger with the largest battery, which means I can't buy an inverter. Having charged the battery several times now, once on the F350 and again on my Prius, I can say that this device was worth the extra money. Reliable and charges as fast as plugged into an outlet. I didn't know if it would work, but it's better than I expected. The charging time is less than 30 minutes with the fastest Stihl charger. Good product! Buying the right inverter is quite difficult, so do your research before making a purchase.
