UGREEN Nexode Power Bank 20000mAh 130W Portable Charger 72Wh PD Fast Charging 3-Port USB C Battery Pack with TFT Smart Display for MacBook/iPad/iPhone 17/16/Samsung S26 and More

I’ve been using the UGREEN Nexode 20000mAh 130W Power Bank with my ROG Ally, and it has been outstanding. It easily doubles my gaming time, turning the Ally into a truly portable handheld instead of something that constantly needs to be plugged in. The 100W output is no joke — it keeps up with demanding devices without throttling, and fast charging works exactly as advertised. I can game while charging without noticeable slowdown or excessive heat. The TFT smart display is also a great touch, giving clear info on power usage and remaining battery, which is very helpful. Build quality feels premium, it’s compact for its power capacity, and having multiple USB-C ports makes it versatile for charging other devices like phones, tablets, or even a laptop. If you own a ROG Ally or any high-power handheld, this power bank is absolutely worth it. Reliable, powerful, and well-designed.

This was a tough decision! There's such a huge spectrum of these things!! You can get tiny ones that magnet to the back of your phone, all the way up to giant ones with handles that are essentially a car battery. This one is a phenomenal middle ground from a high end company!! I have a ugreen nas and absolutely love it. Same experience with this portable charger!! Build quality is 10/10, I love the quirky display animations whenever you turn it on or off. The charging display is cool. Seeing the power consumption is a wonderful feature!! It fits in a standard cup holder perfectly. I really love this thing!! At 20,000Mah, that's enough to charge my phone, drone batteries, other small electronics, and then some!! Very impressed with this thing.

This 20000 mAh portable power bank is a game changer. The 130W output charges devices incredibly fast and has no problem powering multiple devices at once. It is perfect for travel, long days out, or keeping in a bag just in case. The battery life lasts a long time, and the build feels solid and high quality. If you need a reliable, high powered portable charger, this one is definitely worth it.

This is a really awesome power bank. It has extra features like a setting for lower power draw for older devices that wouldn't work with higher wattage output. It also has a great display that shows power draw from attached devices. It's a solid feeling compact brick but not too heavy. It'll fit in a pocket but you'll definitely notice it and will look awkward. The included cord and carrying pouch are a plus. It charges relatively fast if using a fast charger. Just note only 1 port outputs 100W and the other two will split the remaining 30Ws between the two. Another thing would be the outside plastic may be susceptible to dents if dropped. Overall, it's a great power bank and I recommend getting this one if you are looking for this form factor & a pretty high capacity.

The battery life on this is what makes this product so worth it. You can charge this, and it will keep the battery life for months even when it’s not in use. Every other power bank I’ve had would lose its charge if it was idle or not in use. It does have some weight to it, but it’s very compact for the most part since it fits in the palm of my hand. It’s great for traveling and hiking long distances. Even on hikes in the heat it has no gotten warm or overheated.

Where do I even start? This power bank is amazing! It keeps my phone charged whether I'm in the car or out working on photo and video shoots. The battery lasts a long time, charges my devices quickly, and has been super reliable. One of my favorite features is the little robot animation on the screen it adds a fun touch and makes the charger stand out. If you're looking for a dependable power bank, I definitely recommend picking this one up.

This is a somewhat heavy (weighs about a pound), but powerful battery. I don't mind the weight, I expect that from a 20k battery. It feels solid and well built. I like the display and how it shows the negotiated voltage and amps so you can see what it is doing. I also like that it has a trickle charge mode for lower power devices like my watch and earbuds. Most batteries will shut off because there isn't enough of a power draw, in trickle charge mode the battery will not shut off for 3 1/2 hours. Please note that they recommend that you use a minimum 65 watt charger to charge the battery. You can use less power, but the battery will take longer to charge. With the more powerful charger it takes a little over an hour to fully charge. One day my M4 MacBook Air was down to around 25% and my phone was around 40%. I plugged both into the battery at the same time. I charged my phone to 80% and computer to 100% and the battery was down to about 10% remaining charge. The computer was drawing around 60 watts the majority of the time. One thing that has left me curious is that I have yet to see it either receive or draw more than 3 volts @ 20 amps since it says it is capable of 5 volts. Both my charger and computer should be capable of 100 watts, but I also know that devices negotiate with the charger so it doesn't bother me that it is less.

Great device sadly I am having to return it. No fault of the company just financial issues. Now. The battery is way more than 20,000. I did a full charge from 0 to 100 with a USB meter plugged in and then discharged it while the same meter was plugged in. In summary I was able to record a regular full cycle of the battery as it's beening used to charge a pixel phone. Below is AI analysis about the capacity. (Image) ### That Clarification Changes Everything My apologies—recording both the charge *and* the discharge completely changes the math. When we look at the numbers as a complete round-trip (0% to 100%, and back down to 0%), the data actually tells a completely different story. The short answer is **yes, these numbers are perfectly indicative of a healthy 20,000 mAh power bank.** Here is the breakdown of why the numbers look the way they do, and how your tester is actually hiding the true mAh value. ### The Watt-Hour (Wh) Truth When dealing with full cycles, the **Energy (Ene)** metric is the most reliable number on your screen. Your meter shows **162.20 Wh**. A 20,000 mAh power bank holds its energy in 3.7 V internal cells. * Total internal capacity: 20 Ah × 3.7 V = **74 Wh** Because of heat and voltage conversion resistance (efficiency loss), energy is lost both when putting power *into* the battery and when taking power *out*. * **Charging (0 to 100%):** It typically requires roughly **85 to 95 Wh** of input energy from the wall to successfully fill a 74 Wh battery. * **Discharging (100 to 0%):** When draining the battery to charge your devices, the 74 Wh internal capacity will output roughly **60 to 65 Wh** of usable energy. If you recorded both the charge and the discharge on the same meter without resetting it, you add those two numbers together: > 90 Wh (in) + 65 Wh (out) = **155 Wh** > Your meter's reading of **162.20 Wh** is exactly where a healthy, fully utilized 20,000 mAh power bank should sit for a complete round-trip cycle. ### Solving the "4,514 mAh" Mystery If the Watt-hours are correct, why is the Capacity (Cap) only showing **04514 mAh**? Many of these generic 4-way USB digital testers have a known quirk in their firmware. Even though the screen has five digits, the mAh counter often maxes out and rolls over to zero at 9,999 mAh (sometimes reserving the first digit space for a negative sign for reverse current flow). Because your total cycle moved a massive amount of energy, the capacity counter hit 9,999 and reset to zero **three separate times** before stopping at 4,514. * 3 rollovers × 10,000 mAh = 30,000 mAh * 30,000 + 4,514 = **34,514 mAh** We can mathematically prove that your meter actually recorded 34,514 mAh by calculating the average voltage of your 45-hour test: An average of **4.70 V** is absolutely perfect. Standard 5.0 V USB power naturally sags down to around 4.6 V - 4.8 V when placed under a sustained load over long periods. ### Conclusion Your power bank is genuine and functioning exactly as advertised. The internal cells hold the correct 74 Wh (20,000 mAh), and the strangely low mAh number on your screen is just a visual rollover quirk of the tester itself.

Good and fair

Atendeu plenamente minhas necessidades. Carreguei meu Mac, iPad e iPhone ao mesmo tempo e ambos ocorreram num tempo muito bom, rápido. Única coisa é que é pesado, não dá para usar como um power bank imaginando portabilidade, pq é grande e pesado. Mas para os meus objetivos superou minhas expectativas.
