I did a second test with the WiFi extenders that I bought for "fun" and here's a summary of how they were.
.
WORKING and least expensive: Comfast Wr-370AC 600Mbps 2.4G/5G Dual Band Wireless USB Repeater Amplifier WiFi Extender Booster. Price $14 free shipping on eBay. Worked with portable power bank.
NOT WORKING: Wodsys WD-4602 Wireless Range Extender Wifi Repeater Dual-Band 2.4GHz, 5GHz USB Long Range Fast. They mis advertised it. It's only a WiFi adapter. $20
WORKING: Edimax EW-7288APC, $25, much larger than Comfast, can't articulate, worked with portable power bank. $25.
WORKING: Asus RP-N54. $25. Required 110V power.
The advantage with using the working extender as many people mentioned is much more stable video feed from the Breeze to the phone or tablet.

Thanks for this info. I have been looking for a repeater so I can control my drone with my phone that only supports 2.4ghz.
Did your Comfast WR370AC work with a 2.4ghz phone, or does your phone already support 5ghz?
I wonder what the difference is between the Comfast WR370AC and WR371AC
