Question: Is this mini charger/adapter compatible with the Ambient Weather WR-090 Emergency Pocket AM/FM/WB Weather Alert Radio?
Document: Works well...however, warm to touch after a short while,  Works well with the Ambient Weather WR-111B Emergency Solar Hand Crank AM/FM/NOAA Digital Radio, Flashlight, Cell Phone Charger with NOAA Certified Weather Alert & Cables
This charger does the job in minimal time. I highly recommend it for a quick charge to the Ambient Weather WR-333 Emergency Solar Hand Crank Weather Alert Radio, Flashlight, Smart Phone Charger.
Portable emergency radios are a good thing for those times when they're needed in a crisis, but why do they have to be reserved for just emergencies?Bought thisAmbient Weather WR-AC1 Mini-USB to AC Adapter for Small Electronic Deviceswhen I decided that my emergency radio was worthy of keeping on the desktop for simple FM background music. It's true that myAmbient Weather WR-111B Emergency Digital Radiocame with the USB adapter, and that does fine when plugged into my PC or into one of the USB to AC adapters that so many of us have to power various devices.
But there are times that those are in use, so instead of unplugging and re-plugging, this AC adapter is a good solution.This AC adapter will power a number of different Ambient Weather devices as listed on the product page. It's also the same one that comes standard with the highly-ratedAmbient Weather WR-334-U Emergency Weather Radio, which frankly influenced my decision to get it here.TheAmbient Weather WR-AC1 Mini-USB to AC Adapteris a good one. It's highly recommended as it offers full-time power plus recharging.4/28/2013
Ambient Weather WR-AC1 Mini-USB to AC Adaptor for Small Electronic Devices serves its purpose well would buy again if needed
The mini charger makes it easy  to use the emergency radio as an every day radio. No need to crank the radio or use the solar option.
Personally I feel as though this item should have been included with the Ambient Weather radio but since it was not, I felt that it was important enough to have it. It is an adapter - it does the job and I think if you purchase the emergency radio, this is a must have.
Item was quality and arrived in perfect condition. No problem with shipping or packaging. Radio and charger works great. Just tested with a Pacific winter storm. NWS weather alert alarm used several times. Happy with my order.
A must have for your ambient  radio. for around the house to keep it charged for emergency purpose. I have 2 radios and 1 adapter.

Answer: Yes, it is compatible.  I've got it plugged in continuously.
