GZSZSBT 30W Universal AC/DC Adapter Multi-Voltage Regulated Switching Power Supply, with 8 Optional Adapter Plugs, Suitable for 3V to 12V Household Electronic Products and LED Strip, 2A Max

I haven't used it much I found the cord I lost. But wish the plugin was made bigger to put a lil drawer for the pieaces cause I lost 1 already n never even used that yet. I'd like more if u got the choice for USB charger or a c charger instead. Or came up with something connected to the wire with a pouch even to put pieaces in to not loose them. Otherwise also I wish it felt a lil better n not seem so cheap but is wat it is

I purchased a Blackview laptop that came with a European wall plug so I've been using an adapter but the adapter isn't tight so I need to make sure the plug from the laptop is positioned straight whenever I charge. For this reason, I wanted to get an adapter with a plug made for a US socket.My laptop specifically uses a 30W 12V charger with a 3.5*1.35mm tip. I know this because I have the schematic for the OEM charger. Based on the Amazon product page this universal charger should be perfect. It's 30W. There's a dial that allows you to select the voltage from 3V to 12V. According to the table on the product page which links the letter on the side of each plug to its size--information that isn't included inside the box with the charger so you need to go onto the Amazon product page to see the chart size chart--plug H should be a perfect match for my OEM charger--except it isn't. The plug looks right to the naked eye but when I placed the two plugs next to each other facing opposite directions the plug provided here is actually is slightly longer than the one on the OEM charger even though on paper they are supposed to be the exact same size. I'm not saying that plug H wouldn't charge my laptop but I never tried it because I didn't want to take the chance of causing damage.I uploaded several pictures to show the difference in length between the plug on the OEM charger and the one on the tip provided here. A charging plug that's even a tiny bit longer than the one the original device was designed for can easily damage the charging port because that plug is going further in than the manufacturer's design.Since the plug here was not an exact match for the one on my OEM charger I never used this product--I boxed it back up and returned it to Amazon. There is every likelihood that this universal charger would have worked but I would much rather use an adapter for the European wall plug on the OEM charger than take a chance on using this. I have personal experience in the past with universal chargers like this one damaging devices over a period of time until they can't be charged anymore--that's the reason I haven't purchased this type of charger with a tip assortment in years.If you can find a proper replacement charger for your device I very strongly recommend purchasing it instead of a product like this even if the proper one is a lot more expensive. A universal charger might seem like the better deal because of the versatility the assortment of tips provides but as you can see from my pictures those tips aren't always exactly right even if they do charge your device when you plug them in. A product like this should only be used as a last resort.

As title states. I did not receive the power adapter, I got a crumpled, empty box. It took 2.5 weeks to arrive. I wouldn’t recommend because there is a chance that you will also receive an empty, crumpled box.

I was browsing through different AC Adapters to replace the broken 5-Volt power supply for my TV box. What immediately caught my eye is the multiple voltage the GZSZSBT offers in spite of the price being lower than other single voltage units. This means that I can use this not only for my TV Box but for testing various electronic gadgets as well with a wide range of voltages. And not only that, it has adapters for different input port sizes which are easy to plug in, and it even has a built in USB port on the unit which is why I'm giving it 5 stars for versatility. Voltage settings are easily changed with the enclosed Key. And it worked perfectly on my TV Box when I set it at 5 volts. Wattage is also sufficient to power a wide array of power-hungry gadgets. Highly recommended.

Bought this to power an aerator in my garage for keeping bait fish alive - it definitely works as designed and advertised. Have not had opportunity to use other adaptors, but would expect the same result...beats going out and purchasing all those different D/A adaptors!

I always misplace my cords. Sometimes I will misplace a cord and will actually stop using that product. I know there somewhere. But....do I really want to search high and low for an item that will force me to vacuum. I lose stuff. I use this now with my portable DVD player , my cordless vacuum cleaner my portable fan ( that's why I lost the cord. Lol. ) I have those cords someplace , hopefully. It's just a great for peace of mind. And to completely honest I actually bough a similar product ,used it a couple few times and I kinda misplaced it.

Had a transformer for a medical device fall out of the power socket and break the first week I had it. Replacement: $30 in a week. Not good.This one: $14, 2 days, and it took 5 min to set & pick the correct fitting. Still working perfectly 6 weeks later, non-stop use.

Muy bueno está conectado permanentemente a la batería de mi generador.
