- 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)

It's a power bank. That said, I have a number of them but this one is the best I've used so far. It charges quick, charges my phones quick, and has good port options. For what it is it is a bit on the heavy side. I can get 3-4 charges out of it between my Samsung Galaxy S21 Ultra and Google Pixel 9 Pro. The side display it quite handy as you can see it when you've got your phone sitting on top of the charger. I did try connecting two power sources to the two USB C ports to see if it would charge the power bank faster but, as expected, it was not happy and wouldn't charge. So only use one USB port to charge the power bank. If the power bank were to get lost or stolen, I would definitely purchase the same one again. The only downside is no wireless charging - but I knew that before buying so I can't downrate it for a feature it doesn't have. I've got another power bank with wireless charging and I much prefer the corded units. Makes using you phone while charging much easier.

Nice charger, works well to charge your devices. I had no difficulty with charging any of mine. However, it is a heavy device and larger than my other portable charger. I certainly could not carry it around in a pocket unless that pocket was a heavy overcoat pocket. I don't plan on carrying it on my person but will include it in my luggage when traveling. I don't plan on flying with it as it is probably not something safe in an airplane. Most batteries aren't. And this is simply a rechargeable battery.

Excellent power bank charges quickly and last a long time I can charge my phone several times without problem the digital screen is very useful and the included cable is a good extra

Must have if you travel or need backup power to charge your devices. It’s little on bulky side but works great. I am able to charge my iPhone at least 2-3 times in single charge. Not super fast but it’s good.

Update: I also found that this battery claims to support PPS at 5-11 4amp. However , my phone doesn't pull in excess of 3 amps even though it has no problem doing 4amp with the wall charger with identical PPS spec. That's unfortunate, because it is a difference between 45w charging and 27 wt charging in this case . What gives ? 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 .

Multiple ports, fast charging. Great for long driving trips with use for multiple devices. Great price, I thought it would be more money. Thanks to Amazon for so many products available and such super-fast shipping to my front door. I hope you stay number one in the retail market. I will be a forever customer!

Works as advertised.. Charges my phone FAST!!

This portable charger is just awesome! It is so nice to be able to take this with me & charge my phone on the go-- it will no doubtably come in very handy for traveling later this summer. This company also provides outstanding customer service, and has already proved their high level of integrity with me, & I highly recommend this product & this company. Outstanding product from an outstanding company... You just can't go wrong with such a winning combination.

By far the worst product I have ever wasted money on. After one month, the battery no longer allowed me to shut it off so it would just drain over the course of a day. After two months, it no longer will charge anything larger than a phone. So it won't charge my laptop which is the whole point of why I bought it. If I try to charge any laptop it does not indicate that it is charging or even plugged in. It will for a phone however.

Voor dochter vakantie. Is degelijk toestel. Heeft haar de vakantie goed doorgeholpen in de bergen.

Works great. Charges fast with a good cable and a 65W charger. It also provides a fast charge to my phone. I get close to 4 charges with my Galaxy S24 Ultra from one power bank charge.
