Arrived next day, already charged 2 different computers so well worth the money! Has plenty of tips for many various applications. Only warning I see is that since it's new and plastic connectors they are tight so be careful NOT to bend the prongs pushing them into each other, but once in makes good connection.

Review for ZOZO 90W 15V-20V, Model PA-3900-Z, ASIN B0132ST35Y INTRODUCTION & WHY I BOUGHT THIS ------------------------------------------------------------- I am an independent computer handyman and occasionally I encounter a laptop with a power problem that may or may not be caused by a faulty power adapter. A universal power adapter is a good tool to have so that I can verify that a new power adapter will solve the problem before buying one for my client. Sometimes the DC jack in the laptop is faulty, and in one Lenovo IdeaPad it was apparently the power circuitry on the motherboard that had gone bad, preventing the power adapter from powering the laptop or charging the battery, though the laptop was able to run on the battery after I charged it by alternative means (I had eliminated the power adapter and the DC jack as the problem by replacing both). I looked at several universal laptop chargers before selecting this one, and there was not much to distinguish any particular brand. The features I wanted were: 90W capacity (both in case I need that much power, and so that it will have more robust components), a wide voltage range (many have a range of only 18V-20V, which may be all I'll ever need, but I don't know), and a wide variety of charging tips (this has 16, many have 12). I had no clear reason to select this brand except that it seemed popular. DESCRIPTION & TESTING (this does work on Dells) ----------------------------------------------------------------------------- The seller's descriptions and photos all match the unit I received. The unit is made in China. The build quality seems as good as any power adapter. It looks and feels solid. It came in a small, sturdy cardboard box with a hinged lid which I will use as a storage box to keep the adapter and its parts tidy (7.5" x 5.7" x 1.9"). The tips were in a small ziplock bag. The DC cord has a Velcro strap attached but the AC cord has only a twist tie. I added my own Velcro strap. The DC tips are imprinted with both the output voltage and with the M-number, which can be used to look up the tip in the reference table included in the box. The tips fit very securely on the DC cord using a 3-prong connector, and so far they have fit the laptops perfectly (as well as the originals). The power brick is about a typical size and weight for a cheap 90W adapter. It has a green LED to indicate that it is receiving power. The AC cord fits very securely in the power brick. It is 6ft in length, which is fine, but the DC cord is only 45 inches, which is rather short. I do not anticipate this being a problem for me since I will not be using this adapter often or long term, and so the inconvenience will be minimal. However, if you intend to use this unit as your primary power source, you may find the DC cord to be too short if you want the power brick on the floor rather than on the desk with the laptop. A benefit of the short cord for people like me, though, is that it will make the cord quicker to bundle up after use, and the unit easier to fit in my tool box. I have tested this adapter so far on an Acer Aspire M5, three different HP Pavilions, a Gateway NV79, and four different Dell Inspirons (15 2558 from 2016, 15R-5521 from 2013, 1545 from 2010, E1505 from 2006). I will continue to test it on laptops that I encounter and update this review if I run into problems. So far it has functioned perfectly, being able to power the laptops and charge their batteries. I have heard that Dell laptops often reject non-Dell power adapters. I do not know if this is true, but it is not true of this particular adapter. I have not had the opportunity to run this adapter at its full capacity to see how hot it gets. I did just stress test it on the Gateway NV79 (65W) I am using to compose this review, using OCCT's power supply stress test (which runs both the CPU and GPU at max stress to consume as much power as possible), while also charging the battery. I ran the stress test for 20 minutes with the power adapter sitting on a carpeted floor. It became quite warm, but not more than I was comfortable with, and not nearly what I would call hot. During normal, light use of this laptop, the adapter becomes only mildly warm. Keep in mind that if you have the adapter under blankets or other insulators, it will likely build up much more heat. Allow your electronics some ventilation. LOCATING POWER REQUIREMENTS LABELS ---------------------------------------------------------------------- If you do not see a power requirements label on the bottom of a laptop, check under the battery. One HP Pavilion had that information, as well as laptop model information, inside the battery compartment. PROS ---------- - Wide voltage range and tip variety. - Seems well constructed and plugs fit securely. - So far the adapter seems reasonably power efficient judging by the heat output (I have not tested a full 90W draw, however). - Includes a Velcro strap for the DC cord to keep it coiled up. CONS ---------- - The DC cord (the one that connects to the laptop) is quite short at under 4ft, but as a diagnostics tool this may be a benefit due to its compactness. - I would like to see a Velcro strap on the AC cord (only the DC cord has one - the AC cord has only a twist tie).

I ordered within hours of purchasing the previous night and received it in the morning the next day. The product works well, and I would recommend it to anyone.

It charged 1 of the 2 laptops I purchased it for as I think the other laptop was defective. I am impressed with the quality of this charger and the charging pins. Reason for 4 stars is that it’s very hard to detach/ change charging heads. I believe this is to keep a secure fit but you almost need a pear of pliers to pull them apart. Otherwise it’s a great unit.

Fast shipping ... has connectors for all size chargers!

GREAT PRODUCT

Very nice product and a good value. Has just about all the connectors to use on a vast majority of laptops. Works well

The only reason that I got this ZOZO 90W Universal AC Laptop Charger was to try to power up and load my old 2007 HP laptop, at the very least, just long enough to access and transfer some old files. Unfortunately, although this is supposed to be a UNIVERSAL Laptop Charger, and one of the tips provided DID fit the power port, it not only did NOT power up & load my HP laptop but even when plugged in, the charger did not light up like previous chargers for this laptop did and the way chargers for other laptops do or have done. Even though, I've never really used or needed to use, my old(er) problem-ridden Windows PCs ever since I got my AWESOME Apple MacBook Pro Laptop on Christmas 2013, earlier this year, I was looking for some older files/documents (from long before I got my MacBook Pro) and couldn't locate it on either my MacBook Pro, or any of the jump-drives & external hard drives I could find (though it is entirely possible there is thumb drive[s] or external hard drive[s] in some box somewhere that I just haven't come across). Since I couldn't find it in any of the places I'd thought I'd backed it up, I thought the original copies of those files might still be on either my HP laptop from 2007 or my Acer netbook from 2009. However, I hadn't really used either the HP laptop OR the Acer netbook in a little over 4 years (4 years and a month & a half, to be exact). I pretty much stopped using the HP laptop in 2009 (when it was crashing more than it was working -- and I got an Acer netbook instead) and stopped using the Acer netbook in 2011 (when it ALSO started crashing more than working -- and that Christmas [December 2011/January 2012] I got an iPad mini, which in combination with the I got in 2013, and other devices [like and iPhone] I've been using ever since). Unfortunately after not having used either computer in several years, I couldn't remember where my Acer netbook was AT ALL, and not only was the power cord for my HP laptop completely frayed but the battery was totally dead as well (or more specifically, it was BOTH dead & missing). Actually, the battery had died sometime in 2010 or 2011 (I think), so I'd removed it from the computer and never bothered to replace it, because by then I was using the Acer netbook anyway. But then recently, like I said, I needed to use my either HP laptop (and/or my Acer -- which I haven't been able to find) to locate & transfer some old files/documents to my MacBook -- and since I didn't want to waste money on buying a new battery for a computer I had no plans on using after I'd found & transferred the files/documents, and would need a charger at some point anyway, I decided to get this thinking I could just run the laptop on AC power, get all the files/documents off the HP and then go back to using Apple/Mac products exclusively (like I've pretty much been doing since 2013) and never again have to deal with all the hassles of Windowsn PCs. Unfortunately, when I got this , after trying out several (or the majority) of the charger dongle-tips, I finally found one that fit my laptop. So I plugged it all in, into the laptop and the surge protector, and tried to turn on the HP laptop, and.................NOTHING! It claims to be a "Universal" charger, but clearly it is not. I don't know if I just got a defective one or not, but this charger didn't even light up to indicate that its powered up, let alone enable the HP laptop to load or even just power up. Such a total waste of money -- and because I wasn't about to spend on another laptop charger or battery for a crappy Windows PC (in case you can't tell, I HATE Windows PCs) I've abandoned (at least temporarily) trying to locate & transfer the files/documents from my HP laptop and Acer netbook (assuming I ever even find it!). Maybe at some point I'll manage to find a reasonably priced charger & battery that will actually WORK and I can get those files/documents. In the meantime, I'll just have to manage without it. Very disappointed with this charger!! ★ 1 STAR!!!!

He estado leyendo reseñas de más usuarios y hubo uno en especifico que muestra que el voltaje que brinda es incorrecto, es más alto al que se indica y es por eso que causa mal funciones en equipos como me pasó a mí. ¿Por qué le doy tres estrellas? pienso que es un producto realmente útil si lo que quieres es poder cargar varias laptops que NO sean nuevas, es decir, que ya tengan algún daño en la batería o que directamente no te importe causar daños en la batería a un mediano plazo, y hay que TOMAR EN CUENTA que incluso puede causar algún corto circuito, deja un equipo inservible, y tener que recurrir a una reparación. Hay que tener en cuenta que el precio y la universalidad están bien pero puede causar daños a la batería del dispositivo, y al dispositivo en general, realmente es evidente al notar la sobrecarga en el malfuncionamiento del touchpad. Devolveré el producto y optaré por comprar uno original. Estas cosas siempre pasan con productos genéricos.
