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(Blue)

Holds a long charge and was able to recharge phone multiple times while in Europe and still held a good charge percentage after

It charges my phone incredibly fast and it recharges itself even faster. It can charge my phone multiple times with 1 recharge. Very compact, but kind of heavy.

It's exactly what I needed for long days out and travel, primarily because the power capacity is incredible. It holds a serious amount of charge, easily getting my phone through multiple recharges with power still left over. This means no more battery anxiety when I'm away from an outlet for extended periods. It delivers consistent, efficient power whenever I need it, making it incredibly reliable.What really seals the deal, especially considering the massive power it holds, is its size. This power bank is surprisingly compact and portable. It's not overly heavy or bulky, fitting easily into my bag or even a larger pocket without being cumbersome. It perfectly balances high capacity with genuine portability, making it ideal for travel or just everyday carry. Overall, this is a 5-star, top-notch power bank that delivers exceptional power in a perfectly sized package. Highly recommended for anyone needing reliable, portable charging!

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 .

I love this charger! I only charge it once a week and leave it in my backpack, it’s great when I’m on campus all day.It’s a bit heavy but it lasts a long time before you have to charge it again. You can charge your phone completely 4 or 5 times. And it’s so easy to use and works fantastic.

Great product, so helpful keeping my phone and laptop charged when on the road

This has become my main charger. It has the capacity to recharge my phone and tablet several times and then it can be recharged pretty quickly. The ability to recharge several devices at once was something that I had never considered with my older power blocks but it is such a useful feature of this one that I use it all the time.

I bought this portable charger and it was great the first couple months of use. At about the 3 month mark I noticed that the LED that displays the battery level stopped working properly and became very difficult to determine the battery level for the charger. I got in touch with both the seller and Amazon and they both said that because it was passed the initial 30 day period, im unable to resolve this problem entirely, whether it be a refund or a product exchange. Now I have no choice but to keep this product and guess the battery level every time I use it.
