Review: Powers my Starlink standard dish and router like a champ! - Have our Starlink roof mounted on the RV and use the inverter to power the router when were in roaming mode on the highway. Just plug the cigar lighter adapter into the RV house batteries and plug the Starlink 120v plug into the inverter. The 400 watt capacity is plenty due to the router only pulling an average of 40 watts. Let's us have Wifi on the road. When you get to your campground, put the RV on shore power and plug the router into the RV 120v plug in. We ran like this for 5 weeks and 4,500 miles of traveling with excellent Wifi and no issues.
Review: Works well so far - We purchased this unit for a TV and DVD player in our 5th wheel camper. It has a nice display. It makes a little noise but that is not a problem for us. I like the attachment lugs that are provided. So far it has worked very well.

### ⭐⭐⭐⭐⭐ First decent smaller true sine intverter I have found!
*by H***R on March 11, 2025*

I’ve been looking for an efficient, quality inverter for low loads. After several false starts I finally found it, I have some popular “brand R” true sine inverters, and while I mostly love them they don’t have a model smaller than 700W and they just don’t perform well at lower loads and so I was in the market for a 300-400w inverter with good specs. Pros • The most efficient and lowest standby/quiescent/no load inverter I could fine. • 2 outlets with USB and PD outputs. • Built in LCD monitor. • Fan is temperature controlled and only cones on when it is needed. Cons • Not the most attractive housing compared to others. • Larger in size than some competition (but about 2/3rds the size of respected brand “R”’s 700W unit) • Meter not accurate at light loads. • Efficiency at medium loads only o.k. • Battery screws are the “smaller” size and not the larger current size popular. • Battery terminals were challenging to lock down hard, lacked lock washer and took wrench while other brands worked with fingers. The Fit4Less inverter was my 4th attempt to find one to meet my specs. It does. The no load current was about 210mA or 2.75W, fully ¼ that of the most popular 400W brand amazon that starts with a “B” and 1/3rd the power of brand “R”’s 700W unit. At 120W load it took 147.24 or 82% efficiency. While this doesn’t sound great it is close to others. The other brands I measured were 86% and 89% at the same load. Alas I had a 120W load and a 600W load so was unable to test closer to the 400W rating. Since I am mostly using this inverter at <100W loads the excellent standby power was a bigger deal to me than the 4% loaded difference of similar sized units. The built in meter was about 10W high with a 15W load but within 0.5W at 120W. Overall I’m very pleased but do wish I could find something slightly nicer, even if it was 2x the price.
