NOBIS Portable Charger, 20000mAh Power Bank, 45W Power Bank Fast Charging, Battery Pack with C to C Cable, Battery Bank with Digital Display for iPhone Android Laptop etc(Black)

Some, but probably limited use for laptops
There’s a lot to like about this one.Charges at 45w and starts tapering pretty late (did not notice exactly when, but in 70s % still goes at 45w). That’s rather great.Most laptops will want 65w maximum at peak, but I was able to feed lenovos with dc adapter quite ok, they will draw between 11 to 30 w when mostly idle. I was also able to use it with Mac book pro, it won’t charge it battery all that much, but it will cover it needs at idle, or when pinned, will still delay the main battery depletion. So it is not a total replacement or a power source with a completely discharged laptop, but it can be used as a support quite ok.Speaking of laptops, you can probably get quite beefier banks that can discharge at 65, 100, and ever 145 w, but they would be quite more bulky and more expensive. This hits a value sweet spot.Capacity wise this battery seems to be rated at 74wh, if label is to be believed, which indeed would put it at 20ah for traditional 3.7 v cells. This is probably a source of confusion for some other reviewers, who noted 13ah rating — but as it is mentioned, it is usable capacity at 5v/3a. If we put it into wh, for that particular draw that would be 13 x 5 = 65 wh usable battery capacity, or about 88 percent of total battery size (74wh). Which is quite typical, on paper there is nothing quite contradictory here.I did not do any real world tests though for the usable capacity, but subjectively it feels adequate for this size, compared to batteries I had before.On the plus side, it is reasonably compact and light. I traveled with it internationally, it did not raise any flags. IIRC, the united airlines rules stated that only 2 batteries are allowed in the cabin for capacities 100-160 wh, and for below 100 wh there is no specific limit. So this should be ok. The only complaint I got is that the print stating 74 wh capacity is hard to see on my green version, in case a tsa agent wants to see it. But this seems to be reliably under the limits it would seem.As for the phones, 45w draw is plenty. My 2024 Android phone can’t even draw more than 30w at peak, and when it does take that much, it doesn’t last long.So while today there definitely are bigger and more powerful outputs out there, this one seems to hit the sweet spot of portability, usability for travel, and value, for me .

Very good power bank
Very good power bank that is able to charge and discharge at a high rate. Took it on a very active trip to Europe and had multiple devices charging at the same time while at dinner times without issues and fairly rapidly.

Bang for your buck
Alot of times you buy products that seem really cheap or have some kind of defect, but this powerbank is not one of those. This powerbank manages to hold a charge for along time and it supports super fast charging, another good thing is the capacity i can fully charge my s24 ultra from 20% back to 100% 3 times before i have to charge the powerbank, suprisingly its very small and lightweight. The only con is the cable it comes with is very short but other then that its great.

Looking at this one? GET IT.
Hands down, the best purchase of my trip. I use a laptop charger for “super fast charging” at home and this bad boy is comparable. Gives me a little more than a percent per minute. 30m on this charger during a meal and I’m back in the 50% range.I bought this for a week at Disney and frankly, it’s going to chill on my desk at work when I get home. I have been using my phone constantly, between taking nearly 1000 videos, 500 pictures, using the app for the map and fast passes… and I’d say from 9am to 1pm, my battery is already hitting 30%. So we grab food, I charge while we’re eating, and I’m back at 85%.Best part is I can charge while using the phone, so in a pinch, I’ve been able to use a longer cable and just run the charge from my backpack to the phone in my hand.If there is a downside at all, it’s weight. The block is heavy. But it’s not crazy and the weight feels logical and since I’m using a light drawstring back-bag, it has not bothered me a bit.This thing has given me 4 charges per day – 2 for me, 2 for friends, and then I charge the brick itself overnight while we sleep. Absolutely the best thing I bought for this trip. It has taken that low battery stress out of our trip. Well worth the price.

Amazing product. It has lots of wattage and holds a charge. Stylish and works as says. So good I bought a second one. Makes a good gift!

Sehr schöne powerbank mit einem guten Look sieht jetzt nicht nach China Ware aus und das beste ist mit 45watt schnellladen wenn man nur ein Gerät anschließt einfach super. Hält was es verspricht Kauf Empfehlung.

Me gusta mucho esta batería externa, es capaz de cargar mi Poco F5 pro de un 20% a un 90% en menos de media hora incluso usando el teléfono. Y solo usa un 25% +o- de la carga de la batería externa, lo que me daría para unas 4 cargas. Perfecta para eventos largos de Pokémon Go y viajes.
