Baseus 20000mAh Compact Portable Charger 45W, CCC Certified Power Bank Built-in USB-C Cables, Travel Essential PD Fast Charging Battery Pack for iPhone 17/16 Series Galaxy S25/S24 Ultra Google iPad

I’m really impressed with this power bank. It’s compact, works great, and holds a LOT of power. I tested it with my phone at 50% battery at 9:25, and by 10:20 my phone was at 100%. What really impressed me was that the power bank still had 84% battery left afterward, so I was able to give it to my daughter and she continued charging her phone with it. I also tested it when my phone was down to just 9% battery at 8:27, and by 9:03 it was up to 52%. That’s a pretty good charge in a relatively short amount of time. My only complaints are that it’s a little bulky and heavy to hold, and I wish the cables were longer and retractable. Other than that, I really like this charger and would definitely recommend it. It has honestly been a lifesaver, especially for my daughter. She takes it with her to campus all the time, and it’s nice knowing she has extra power with her whenever she needs it. Definitely worth having!

This has quickly become the most trusted item in my travel bag. This charger claims to be able to charge up to 4 devices at once, and sure enough, it actually does. A common scenario for me is quickly topping up my tech at the end of a business day. With this power bank, I can charge any combination of my smartwatch, earbuds, phone, headphones, tablet, and video camera, and 4 of them can charge up no problem with no noticable heat. And for a 20000mAh power bank, it's surprisingly compact. With a 45W output, this can easily charge all your low-powered devices at the same time. Perfect for those on the go, especially because it comes with two built-in USB-C cables. Most power banks on the market only come with one or no cables. TRUST me, two built-in cables is so convenient and better than trying to wrap a cable around a power bank that you will inevitably forget at some point. It claims to have a 30W input, which I also confirmed. Impressively fast for a power bank at this price point. The built-in screen is also really handy. I like this so much more than my older power bank that only has 4 lights to show a rough power level. Also, something that many people haven't realized yet is that their power banks can be confiscated if they travel to China without a newer "CCC Certified" charger, no matter how well it still performs. For that purpose, I would easily recommend the Baseus power bank.

I am thoroughly impressed with this Baseus power bank. For its compact size, it packs a serious punch. What I Love: True Fast Charging: The 45W output is a game-changer. It easily fast-charges my phone and can even give my laptop a solid top-up when I'm away from an outlet. Built-in Cable: The integrated USB-C cable (visible in 1000124552.jpg) is incredibly convenient. I love that I don't have to worry about packing an extra cord when I walk out the door. Clear Digital Display: The LED screen clearly shows the remaining battery life, so there's never any guessing about how much power is left. Great Form Factor: It fits comfortably in one hand and slips easily into a pocket or backpack without feeling heavy or bulky.

This power bank didn't disappoint! I've used Baseus power banks before and their other products and they are a trustworthy brand for me that keeps improving. The first thing I noticed is how solid and premium it feels. It has some weight to it, but for a 20,000mAh charger, that does not really surprise me. I would rather have something that feels sturdy and reliable than something light and cheaply made. The built-in USB-C cables are easily my favorite. Not having to search for an extra cable makes this power bank so much more convenient, especially when I’m traveling or out for a long day. Just put it in my pocket or a small bag and I don't have to worry about forgetting a cable :) The battery percentage display is also a big plus because I can see exactly how much power is left instead of guessing from a few blinking lights. Charging speed has also been very impressive. 45W is plenty fast for my phone and tablet. Paired with the large capacity of 20000mah, it can last a day and even more. The only small downside is that it is a bit heavy if you plan to carry it in a purse or small bag all day, and the shorter built-in cable can feel slightly awkward while using the phone. Still, those are minor trade-offs for the capacity, speed, and convenience it offers. Overall, this is a well-built power bank that is perfect for travel, daily use, or anyone who has multiple devices to keep charged. It is compact for the power it provides, charges fast, and makes life easier by keeping the cables built in. I highly recommend it!

Bought this as a semi-permanent backup battery for my older iOS devices and as a travel backup. Haven’t yet traveled with it, but it works very well to keep my assorted old batteries charged & working! I’ve noticed that the charger is, itself, rather slow to charge and this one gets quite warm while charging. I also noted that the LED numbers are quite difficult to read, as is the instruction manual. The device seems solidly put together & I especially like the attached cables!! Definite bonus for traveling, as the built-in cords you won’t have to pack! Size-wise, it’s excellent, although a bit heavier than anticipated. Seems to charge my devices just fine, with adequate speed….but as I said, it’s used as a traveling backup for older devices which generally are not totally discharged.

As I was looking for a power bank, I ran across this Baseus one with 45W rating. I have several Baseus products and since I've experienced their customer care before was immediately curious. I know they put out an amazing product and a great value, I was immediately sold. For the size battery it charges quickly as long as you use a rapid charger. The 2 cables plus 2 ports are convenient. The output is as advertised, but note that with any charger the more items attached lower the output. The digital display is a nice touch.

JagMan’s FNB58 readings of this Baseus 20,000mAh charger may be accurate, but the conclusion that the Baseus power bank is “nowhere near 20,000mAh” is likely based on comparing two different measurements. He interpreted it wrong. The advertised 20,000mAh rating refers to the power bank’s internal battery cells at approximately 3.7V, while the FNB58 measures the mAh delivered through the USB output at approximately 5V or higher. Because the output voltage is higher, the measured output mAh will naturally be lower even when the power bank is performing normally. For this reason, watt-hours (Wh), not mAh alone, are the proper measurement for comparing a power bank’s actual usable energy with its advertised capacity. I did my own testing on this same Baseus model using a more controlled setup: a constant-current electronic load set to 3.1A. The power bank ran for 4 hours and 10 minutes and delivered 62.47Wh, with the tester recording 12,932mAh at the USB output. The advertised 20,000mAh capacity is equivalent to approximately 74Wh at the internal battery voltage. My measured 62.47Wh output represents about 84% of the rated internal energy, which is a reasonable result after accounting for normal voltage-conversion losses, internal electronics, and the power bank’s low-voltage protection. JagMan’s result of approximately 10,000–10,900mAh does not automatically prove that the power bank lost nearly half of its capacity. Without knowing the Wh reading and the average output voltage, the mAh figure alone is incomplete. Depending on the voltage used during charging, his measured mAh could potentially represent an amount of energy much closer to the expected usable capacity than it appears. The FNB58 can measure Wh, so that number would be much more useful for determining whether the units were actually underperforming. His testing method also used several different phones rather than a constant electronic load. Phones continuously change their charging current depending on their battery percentage, temperature, charging protocol, screen activity, and battery-management system. That makes charging multiple phones useful for testing real-world performance, but it is not as consistent or repeatable as discharging the power bank at a fixed current. A controlled constant-current test provides a clearer measurement of the total energy the power bank can deliver. The complaint about two phones charging more slowly is also separate from the capacity issue. The 45W rating is the power bank’s maximum supported output, not necessarily 45W available to every connected device at the same time. When two phones are connected, they share the power bank’s total available output, and the charging speed can also depend on the devices’ charging protocols. Therefore, receiving less than 22.5W per phone does not by itself show that the power bank is defective. Overall, JagMan may have correctly recorded the USB-output mAh, but the review appears to interpret that number incorrectly by directly comparing it with the advertised 20,000mAh internal-cell rating. My controlled test measured 62.47Wh of usable output, which is approximately 84% of the power bank’s nominal 74Wh internal energy and indicates that the Baseus E00311 is performing within a normal range. The key missing information from JagMan’s test is the Wh measurement; without it, the claim that the advertised capacity is “way off” is not adequately supported. In conclusion, this power bank does output the nominal amount of power and evergy as expected. I bought one and have no regrets so far.

I am very happy with my Baseus power bank. It is compact, lightweight, and easy to carry wherever I go. It fits comfortably in my bag and doesn’t take up much space, making it perfect for travel, work, or everyday use. One of the things I like most is how convenient it is to use. Charging the power bank itself is fast, so I don’t have to wait long before it’s ready to go again. It also charges my devices quickly and reliably, whether it’s my phone, tablet, or other electronics. The build quality feels solid and premium, and the battery capacity is more than enough to keep my devices powered throughout the day. It gives me peace of mind knowing I have backup power whenever I need it. Overall, this is a great value for the money. If you’re looking for a portable, reliable, and fast-charging power bank, I highly recommend the Baseus power bank. It has become an essential item that I carry with me every day.

Speciaal voor China aangeschaft, en werkte goed

Tengo un Pixel 8 Pro y con esta power bank cargada al 100% puedo cargar mi móvil 3 veces de manera completa. La power bank es compacta, aunque es más gorda de lo que aparenta en esas fotos. Cumple con las medidas publicadas en el anuncio; es más bien un efecto visual de la imagen promocional. Buen peso para un producto así, se puede llevar en una riñonera sin sufrir mucho, y si la usa para cargar sin que esté guardada en un bolso o riñonera no se calienta mucho.

The quality of this power bank for the price really surprised me. It does offere a really high capacity and im really happy with the charging speeds it provides. The two cables that are present seem sturdy enough and work great. Overall a great product

J’ai acheté cette powerbank pour aller en voyage. Elle a été un véritable atout lors de mes sorties. J’ai pu recharger plus de deux fois mon iPhone 15 pro Max sans craindre de tomber en rade. J’ai fait de même pour ma tablette et les 45w sont un véritable atout. Charge rapide et linéaire.

The best slim, fastest charger for iPhone 17 and later. Since the iPhone 17 supports 40W charging, this charger delivers on its promise. So, in general, if your device supports 40W, you will make the best of it. ++ It is lightweight and portable. +++ I like the screen showing the actual watts it delivers to the device in real time. If the charging power is reduced, it may mean the device's battery temperature is high (possibly due to the device cover) or that it is near the end of the charging cycle, so it slows down. I like the protection and adaptability. +++ Definitely, the embedded USB-C cable is a plus.
