I'll make a few suggestions, following up on what Larry said. First, if you're charging a phone or tablet, by far the most efficient way to do that is from a 12 V outlet--no inverter needed. You just need the USB charging cable that came with your phone and your iPad, plus a 12V to USB adapter. I've been using these Anker brand adapters for a couple of years, and they work fine.  If at all possible, I recommend going that route.

With regard to inverters... either a 175 watt or 225 watt inverter is way more power than you need for charging a cell phone or an iPad, which only need 5-20 watts. It's physically bigger than it needs to be.

For low-power tasks such as charging cameras, small batteries, toothbrushes, and so on, I use small 75 W Bestek inverters. They work fine , and they're small and easy to store. Like the larger Go Power units, they're "modified sine wave" inverters.

If you want to pamper your chargers, Bestek also makes a very compact 150 W "pure sinewave" inverter. I have one of these as well. I've been using these two models of Bestek inverters for many years and have never had a failure.

So... the Go Power 225 W inverter Amazon sent will do the job for you, and if you want to take the easy course, you can just keep it. It's kinda clunky and not terribly efficient, but if you're just using it occasionally, you may not care. But I really do recommend instead getting a 12V to USB adapter like the Anker unit I mentioned.

As a general rule when RVing, always go 12 V if you can. (Exception: 12 V mini-heaters, hot pots, hair dryers and the like are usually cheaply made, slow, and above all, power hungry.)
