KrisdoniaPortable Laptop Charger 185Wh/50000mAh Laptop Power Bank External Battery Pack for Laptop, Tablet, Projector, Smartphone and Others

Wow this has a great capacity battery! Very powerful and a quick charger for my Lenovo laptop and tablet. It has multiple adapters that are included which is a nice bonus. It's not as heavy as i.thiught it would be, which makes it portable and easily fits into my laptop bag. When you need to charger this power bank it charges relatively fast I feel. Great for bringing to the park, Starbucks or anywhere outside of the home. If your power goes out it's also a great backup!

I bought this to power a MPC One sequencer. This works great. It has multiple power settings and a lot of interchangeable connectors, so it can be used for various power settings. The battery lasts for hours. It's a good shape and not too heavy.I only just got it, so I didn't know about durability, but it feels solid.The only problem I have is the interchangeable connectors stick out a long way, and it's easy to knock them out of the in-port, but that is probably unavoidable.

Great product! Great presentation with packing, has all the accessories needed. Charging speed has been great and length of charge. Very sturdy and seems durable, great value for money, haven’t noticed any excessive heat. Not too heavy.

Great power bank — works perfectly and feels high quality. Charges my laptop and phone fast. Love the voltage options. Very reliable. I'm happy with it.

You get the hint when u unbox and see $40 worth of added cables and connectors for a supposed 50000 mah power bank--so what is the powerbank actually worth(?). and, is there a customer service phone #. Nope.#1 note that all the positive "verified purchase" reviews are by somebody's first name.#2 note that all negative reviews are by a first and last name. Is it possible that Krisdonia is buying its own products and giving the positive review?#3 no one that actually uses this product would give it a positive review.#4 Note that every positive review is in the same genere--lavish general praise of the product for some situation, but none of the positive reviews has any specifics--what will it charge, how quickly does it charge, is it in fact 50,000 mah--i.e. does the fully charged power bank last any appreciable time, etc.#4 As many of the negative reviews have noted--this is nowhere close to a 50,000 mah power bank. I a guessing from my efforts that it is about 15,000 mah. You can connect any of the ports to a celeron chromebook or even my Verizon jetpack modem and it will charge e.g. 30% and at the same time the Krisdonia loses 30%.#5 it will not charge any laptop--e.g. Dell XPS 13--that has USBC3 charging and that is even if u buy the Krisdonia adapter for $20--with all the crap they include with this, which are primarily for e.g. year 2014 laptops--they do not include a USB c cable. Why would they? their supposed USBC port only charges to 12 volts. Note that all the reputable power banks have USbc ports with 40-60 volt output.#6 it takes more than 4 hours to fully charge this thing.My guess is that this Krisdonia is something that was developed around 2015 and they r still trying to sell it. You get fair warning in that there is no customer service for this product. if u r dumb enough to buy it, as i was, there is no way to talk to anyone to get it to work. Note to myself--next time educate urself re power banks before instead of after purchase.

I only tested the charger a couple of times and am going off of my own experience as well as of the other reviews and all the information I was able to get from the seller in the questions they answered. I'm using this charger to power a Wii portably and I'm going to try hooking it up to a solar panel and using it as my primary power source for a car trip in the near future.The Good:-The adjustable voltage is ONLY FOR THE DC Output / DC OUT barrel port. I looked a while for this and felt I should include it here. That's great because you can charge your laptop and your phone or other devices simultaneously without worrying about frying anything.-Automatic voltage negotiation/detection for most ports: Kind of ties into point above, but the other ports don't need the voltage to be set, only the DC out.-Solar charging: The 19 Volt input means it can be used with compatible solar panels.-Fast charging: 19 Volts @ 2 Amps also means this should charge nearly 4 times faster than your phone, which is good because the battery is ~11x bigger than the one in my phone. That means this whole thing could be charged in the time it takes to charge your phone 3 times. It will easily charge overnight, which is great.-True Passthough charging: Because of the input power wattage being so high, you can also charge your battery up while charging your other devices. If you're going really heavy with the power usage, you could still discharge it even while it's plugged in if you're charging multiple devices at once / using the DC out at a voltage over 12V, but it will take a while and your devices will probably be charged by then and can be disconnected. This is still a great feature considering you can hook it up to a solar panel and charge the battery and all your devices at once.-Quality construction: Body is made of aluminum, which frankly most power banks should be.-Tons of adaptors: If you're using this to charge a laptop, it definitely will be able to since it comes with an adapter for everything type of laptop that I've seen-It can run a Wii. I had to modify a cable from a spare Wii power adapter I bought, but it can definitely output enough power for that (12V @ ~1.5 Amps) and it can apparently supply even more juice!-Price: I paid $110 after applying a $15 coupon. That puts it in line with comparable powerbanks and $/mAh is a great value compared to other chargers I've had in the past.-Weight:Not too heavy, surprisingly. This one is a bit subjective, but I thought it would be a lot heavier than it is for it's size.The Bad: (negative but not deal breakers)-They supplied every cable they possibly could have except for a UBC C cable. Odd considering they provide a DC to MagSafe cable, which should not be that common, but no USB C?-Carrying case: It's way too small to carry all the cables you'd need it to. It can barely fit the cable you'd need to keep this charged, so be prepared to keep your cables somewhere else.-Lacking documentation: There were instructions included with the device, but they were lacking. Most of the info I have on this device is from reading other reviews and the seller's answers to questions here. A shame because it has a lot of features that would make this an easy sell to people like me who mess around with electronics all day [read as nerds].-Made in China: I'm assuming that means they probably used Chinese battery cells too, which are known to be inferior in quality to Japanese cells. If you don't believe me, you can research this yourself. I didn't open it up to confirm this as I still want to use this so I can't confirm if this is true or not, but something to be aware of.The Ugly:This is reserved for things that should be reasons for you to absolutely not buy this charger. The only thing I can think of is the fact the battery life detection on this is wonky. This thing really doesn't know how much power it has, which can obviously lead to some bad situations where you need power and you don't have enough, but this thing has so much power, I doubt that would be an issue for most people if you keep it charged before you travel. Even if it lost 25% of it's capacity after years of battery degredation, it could get to ~37500 mAh, and that's still more power than most people will need on a day to day basis. I bought it knowing the battery life detection is pretty hit and miss, and as long as you keep charge it every day, it could last several years before you'd need to replace it.

Very happy with this purchase! Came complete with case and accessories (charging cable, connectors, cables) and already charged about 95%. We just charged two phones and an iPad, with 85% power left. Items charged up about as fast as with a lightening cord, and much faster than plugged into a computer. Nice case with side pocket included. This is a solid size (about 8"x6"); not overly portable but will be useful on car trips and during power outages!
