This AC adapter for our Brother P-Touch PT-D210 label maker was a great buy. We recently upgraded from an entry level P-Touch model that had no cord capability. Now that we have the PT-D210, the option of using the AC cord makes label making so much more convenient. The power cord provides a bright LCD screen and seamless label

This is a good AC supply for the P-Touch printers. Other adapters I have used did not deliver enough power to the printer and the printer would display a 'Replace Batteries" error messages when printing a label. Also, be careful of other supplies, the P-Touch requires a connector with positive voltage on the outside ring, and

I plug in the adapter, the green light comes on, and sometimes the label maker (Brother PT-D200) will turn on for about one second. Most often nothing happens. I got it to stay on long enough to print a label once. I know my label maker works with an adapter because I tried one of those adapters with selectable voltage and multiple tips

I read many reviews about customers buying this product and it not working. Some buyers destroyed electrical or electronic devices using this converter.

We're very happy with the adapters - and are using them in UK (Northern Ireland) and Ireland with excellent results. Of course the user has to confirm that the U.S device will work with 240V AC feed. All of our USB chargers and laptop chargers are shown as compatible, and we have had no problems using them through the adapters. We had to

Having traveled outside the US very infrequently, I was delighted to realize (upon assembling my ridiculous amount of electronic gear for a trip to Ireland) that nearly every power supply and charger I own now, even though it has "American plugs", is rated as 110V-220V, which means that I DID NOT need a voltage converter (NOT

These speakers came recommended on a couple blogs, but I was skeptical of anything USB powered, and was nearly certain I'd want something with a subwoofer.

These Pebble speakers are tremendous. I'm no audiophile but I know enough that these speakers produce great sound. And at the price point offered you can't go wrong with them. There is no distortion at loud settings and the bass is actually quite good. The overall quality of sound highlights both high and low midpoints very well. I

If you have read the reviews about the labelers, a constant complaint is how fast they go through batteries, and batteries can be expensive. You can buy this AC adapter for the price of a set of batteries. Now the cord is a bit short, but you will probably use this at a desk. If your cheap label printer does not include an adapter

I put off buying this adapter because I kind of felt like it should come with the labelmaker and you can use the labelmaker with batteries.

I purchased this power supply because it purported to have filtering and be "low noise" because I needed it for an audio application (an Echo Dot connected to high quality external speakers).

LOVE my AC adapter. Works perfectly with my Medela Pump in Style. I got this for my work office. So I have one plug at home and one plug in the office, along with a 'just in case' battery option in my pumping bag.

Delivers exactly on the spec, which few cheap supplies will do. I measured 12.5 V at no load, and 12.0 V at 2.0 A (24 W) output. At no load it draws 0.4 W from AC power, and at full load it draws 30 W. That means it's putting out (30-24) = 6W as heat, and the overall efficiency is 80% which isn't great, but is OK. At full load the

The product puts out the voltage as stated and looks to be good if you need a 12V power supply to quickly power something up on a bench. However, as it has no safety approvals (i.e. UL, ETL, CSA, CE, etc.) I am a bit nervous about having this running un-attended (I need the power supply to be powering equipment in my garage 24/7/365).
