This is wonderful to use when traveling overseas. Charges quickly and keeps a good charge. It’s heavier than I thought it would be.

This thing is awesome. I grabbed it for trips and it has way more power than I expected. The AC outlet is clutch — I can plug in my laptop, charge my phone, even run a little projector. It feels super solid, charges fast, and the display is actually really handy. Honestly just a super reliable power bank that does exactly what you want. Definitely worth it.

I so wanted this to work, but it did not!! Even when fully charged, it barely stayed charged for 2 hours at best. It only charged my laptop and took forever, progressing only 1% at a time. And it is heavy

If you want to avoid trying to find wall plugs at the airport or just trying to have an emergency battery pack then this is the one for you. First thing about this is that I actually had to get a replacement unit. The first unit the power button was actually sinking in and getting stuck so make sure you press the power button a few times when you first get it. It should just be a small press and not go all the way into the unit. This unit is a bit on the heavy side so be aware of that when packing I would say this thing weights close to five pounds more or little less. It is pretty compact so it can fit in most backpacks. It comes with its own carrying bag as well that will protect it from external scratches. The outer layer is a pretty anti slide surface in my opinion so you are not going to be sliding this off of the desk or anything. This battery pack is pretty strong. I tried to power a monitor with it and it actually did for several minutes before running out of power although I would not recommend using this battery for that purpose but it is definitely a good thing to note about it. It has two ways of charging your laptop. From what I can tell it can charge your laptop via type C port or a wall plug that is provided. Be aware that with the type c port charging for the battery you will require a strong power brick to charge the battery. That being said it can actually charge a macbook via type c to type c which is pretty nice if you are trying to charge two laptops at the same time although the charging is extremely diminished doing this. There is an actual number gauge to show how much power is left in the battery which is really nice. I am not needing to guess how much percentage is left before it dies. The charging time for this device can be close to six hours or more from dead to full, but it provides you laptop with up to eight hours of battery life. I was able to power a laptop with no battery for about four hours alone on just this device alone. Be aware that this device does get warm while it is in usage so be careful not to have this device say under a blanket or inside the carrying case when you are using it as the carrying case is made of insulated material. There are also several USB ports to plug in your phone if you need to. You can charge your phone about six to seven times over before needing to recharge your device again. It does come with a type c cable and the charging cable you can plug into the wall. In order to power this device on you will need to push and hold the button for about two to three seconds before it starts working in the wall outlet part of the battery. If you are just charging your phone, all you need to do is press the power button and it should start charging immediately from what I can tell. It does support fast charging for phones from what I can tell which is nice. I really like the battery for charging my macbook or windows laptop. It really has a strong charging capability able to charge your phone and laptop at the same time. It has a rather nice carrying case to protect the battery from external damage. Finally, it allows you to not have to worry about finding that wall plug to charge your laptop while you are traveling.

Excellent portable power bank for travel and work! The Krisdonia 27000mAh charger handles my MacBook, phone, and even a small projector with ease. The built-in AC outlet is super convenient, and it’s TSA-approved so no hassle at airports. Fast charging, solid build, and long battery life make it a must-have for business trips or outdoor setups. Highly recommend for anyone needing reliable, high-capacity portable power.

In light of all the talks of the power grid being shut off and the increase of climate disasters, I decided I should get prepared. So I bought this! I love all the different ways you can plug things into it. It holds a lot of power which is great for longer term usage. I'll be taking this off grid camping as well. The case is really nice too! I need to get a solar power charger and see how well that works with this but I can only buy so many things at a time in this economy so that will be a near future purchase and I'll come back to update you all!

Didn't know it exists such a super compact heavy duty battery pack that charges and Powers with a full AC outlet This would be a lifesaver on the go if you like to road trip and be able to power up powerful machines like laptops etc Very well built and super durable

This little box packs a huge punch. I purchased this to run my dad's portable oxygen machine for a cross Canada plane ride. It worked the whole way, got a quick recharge in the Montreal Airport and lasted the whole way. I now plan on keeping in my truck for work/camping and would highly suggest this product to anyone. My family have now bought another one for our other vehicle as well to power the kids' toys

Product came with a nice carrying pouch and pretty good build quality. My primary reason for buying this was to power my ResMed AirMini CPAP machine for overnight camping without access to a power outlet during the night. Out of the box and charged up to 100% battery before first use, the pack powered a full 8 hours of sleep (my pressure is at 8.0) and brought the battery down to 39%. I'd call that a win!

We used this battery bank nearly every day without fail until we hit the 1 year date. It simply died and off to the recycle bin it went. An excellent short term solution otherwise it's a total waste of money. For the amount, consumers deserve better quality!!

Its somewhat thick and heavy but you want a product like this to feel durable, which it does! The charge lasts quite a long time. Very good product.

Took this on our Safari to Africa and ended up powering up a whole show when we lost power at the safari resort. It was much appreciated by more than our family.
