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)

This portable charger works great and charges devices very quickly. The 20000mAh battery capacity is perfect for travel, work, or long days away from an outlet. I was able to charge my phone multiple times before needing to recharge the power bank itself. The compact design makes it easy to carry, and the build quality feels solid and durable. Fast charging is a huge plus, especially for newer devices. Overall, a dependable power bank that is worth having on hand.

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.

Great battery pack it would charge my phones ve y rapidly and still hold up well not drain quickly. It was a heavier battery pack and this is why I ended up losing it. I would recommend it as it's durable and fast charging and a convenient item to have when traveling.

Works great. Very heavy but as a backup it does the job. I can get a 2-3 charges of one single charge. I like that it has the percentage on the side so I know when it’s in need of a charge.

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 .

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.

Wow I’ve been delaying purchasing a portable charger because half the time it’s just another thing to REMEMBER to charge I love how this tells me the percentage it’s on Doesn’t take long to charge the portable OR my phone (because I frequently forget) and I like how you can charge the charger with any port Little things matter like as soon as I plug it in the portable turns on and then turns off

This power bank definitely gets the job done, especially if you need to charge multiple devices at once. The capacity is great, and it’s reliable when you’re in a pinch. That said, it’s on the heavier side, so I wouldn’t call it the best option for travel if you’re trying to pack light. It’s more of a “throw it in your bag and keep it there” kind of charger rather than something super portable. One small thing that ended up being surprisingly annoying is the charging indicator placement. It’s on the opposite side of the power button, which doesn’t seem like a big deal at first, but with frequent use it just feels inconvenient and not very intuitive :((( Honestly, I probably wouldn’t have picked this one myself, we needed something quickly for a trip, and my husband chose it. It works, and I can’t complain about performance, but it’s not the most user-friendly option for me.

I got this power bank in September 2025 and it's still working great. The cord that came with it stopped working, so I just bought a pair of other fast Chargers. Easy peasy! It is a bit weighty for such a small gizmo, but I don't care about that - I just care that my phone gets charged quickly.
