- 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(Green)

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.

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.

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.

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.

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!

11/30 Vendor Reply in LESS than 12 hours (Exceptional): (My Summary): Batteries hold 20 Ah. Conversion losses eat 35% just like every other vendor. Hence 13 Ah available. I will keep these. - We understand your concerns and would like to provide a clear explanation of how our batteries work. Our external battery consists of two 10,000 mAh cells, with a total rated capacity of 20,000 mAh. However, when charging your devices, several factors cause a reduction in usable capacity due to the following physical and technical principles: Heat energy loss: During charging, the battery generates heat, which consumes part of the stored energy. Internal consumption: The electronic components of the battery's printed circuit board consume approximately 10% of the energy. Losses related to the charged device: Charged devices, such as smartphones, also consume energy in the form of heat, accounting for about 12%. Voltage conversion: Converting the battery's internal voltage (3.7V) to the output voltage (5V) results in an energy loss of around 12%. Taking these factors into account, approximately 35% of the energy is consumed during the entire charging process. This is normal and aligns with industry standards. - 11/30 update: Fine print on this power bank only lists Capacity of 13000 mAh! Will revise review if seller provides clarification. If no prompt reply I will return BOTH of these with complaint to Amazon - Original thoughts upon receipt (11/27) This was a 24 buck Black Friday Deal - and even at the list price of 33 bux THIS is a Deal! It fast charges AND delivers at 45 Watts with a 20 Ah capacity (Airline Safe) - so it will Really fast charge my iPad (Not like those claiming fast charge at only 22W)!. It has 2 USB-c (45 Watt Max PD in/out) and 2 USB-A (30W total) ports. The ports can be configured to trickle-charge for things like ear-buds and smart watches. The digital display is a really cool and helpful bonus. Awesome Versatile Powerbank. So great I even ordered another one for my wife :) Highly Recommended.

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.
