Shargeek 300 (300W、24K、DC ポート、RGB ライト)

The Shargeek 300W Power Bank stands out as a high-performance portable power solution for anyone carrying power-hungry devices. With a 24,000mAh capacity, 140W PD 3.1 USB-C output, and dedicated DC output, it’s capable of charging everything from smartphones and tablets to larger devices like laptops, drones, portable monitors, and camera gear without feeling underpowered.One of the highlights is the transparent housing, which gives it a distinctive tech-inspired appearance while showcasing the internal components. The smart display is equally useful, providing real-time information such as battery percentage, input/output wattage, and charging status, making it much easier to monitor power usage than relying on simple indicator LEDs. The customizable RGB lighting adds a fun touch without being overly distracting. However, turning it off requires more button presses than I care to. So I won't be using this in the bedroom.Performance is excellent. The 140W USB-C output easily handles fast charging for compatible MacBooks and other USB-C laptops, while the additional DC output makes it useful for devices that can’t rely solely on USB-C. Multiple outputs also allow several devices to charge simultaneously, making it a great companion for travel or content creation setups.Something special and Shargeek premium power banks - the DC barrel output. Its useful if you need it. Most of us won't.Considering its power, the battery pack remains reasonably compact, though it’s naturally heavier than smaller phone-focused power banks. That’s an acceptable tradeoff given the significantly higher output and versatility.Overall, this is an impressive premium power bank that combines high output, fast charging, an informative display, and a unique industrial design. It’s an excellent choice for travelers, photographers, videographers, and anyone who needs dependable portable power for more than just a smartphone.

This is an exceptionally well built, futuristic looking, and feature packed power bank. The power bank feels extremely premium with an all metal build as well as multiple transparent windows to see the battery cells inside as well as the circuit board and some RGB lighting.The display shows a plethora of information such as the output wattage of each port, information about the last 5 charge cycles, discharge/full charge limiters, and much more. This power bank also has a very useful voltage adjustable DC port so that you can use this with a DC connector to power something such as a portable fridge.As expected, each USB C port supports the full power delivery 3.1 protocols and supports fixed PD profiles of 5v@3a, 9v@3a, 12v@3a, 15v@3a, 20v@5a, and 28v@5a. It also supports a PPS range of 5-20v@5a. One thing to note is that it unfortunately does not support PPS at up to 21v which means that Pixel 9 and Pixel 10 devices that require 21v PPS to fast charge will be unable to do so here. Finally, the power bank also supports the AVS protocol at 15-28v at up to 140w. The thing that I was most pleased to see is that both USB C ports are fully featured with the full PD 3.1 range of protocols even if both ports are being used at the same time. Many power banks will step down the protocols available when more than one port is being used at the same time but that does not occur here.This power bank charges pretty quickly but not as quickly as advertised. Using a 140w charger, I measured a full charge of this power bank to take 50 minutes and to consume 94.7wh of power. A full discharge of this power bank at 20v 3a (60w) yielded 78.17wh of power which translates to an efficiency of about 83% which is pretty decent.The body of the power bank reaches around a maximum of 41c before the power bank throttles from 140w to 100w while charging. Throttling occurred 28 minutes into charging at 140w (as shown in the attached charging graph image) in my 21c room and the charging wattage dropped from 140w to 100w. It's somewhat disappointing to see that despite the majority of the body of this power bank being aluminum which should be great for heat dissipation, that it is unable to sustain 140w charging for longer. Due to the throttling, the power bank took 50 minutes to fully charge instead of the advertised 44 minutes. While this is not a huge discrepancy, it is still 13% slower than advertised which I thought was worth mentioning. There are other power banks I own such as the Anker 26,250mAh Prime Power Bank that is able to fully charge in about 45 minutes and is quite a bit cheaper than this Sharge 300w power bank. Normally, I would not nitpick about something like this, but due to the high price of this power bank and the fact that there exists cheaper power banks that can charge faster than this one, I thought it needed to be mentioned.Overall, this is a great power bank with an excellent feature set that is probably overkill for the average person. The price is quite high but in line with other power banks that also have features like this. I would highly recommend this power bank if you are a power bank enthusiast such as myself and I think that the build quality is the best out of all premium power banks at the moment. However, I have to deduct a star due to the power bank being unable to fulfill the promised 44 minute 0-100% charge time.

The Shargeek 300w power bank is very expensive for the capacity it offers. If you need a lot of power for a very short time in a compact form factor, then this device fits the bill. However, the charging capacity, as with virtually all power banks, falls short of the advertised numbers.PROS- Shargeek arrived with 70% charge. Took 50 minutes to charge to 100%.- The Shargeek charged a MacBook Air M4 15" from 2% to 99%. Charging took about 1 hour, 35 mins, and ran at close to 70 watts, which I believe is the MacBook's maximum charge rate.- The Shargeek display is very slick and informative. Shows strength of each of the six individual cells.- Uses standard lithium 21700 lithium cells.- Cool looking case has colored lights, attractive display, and is transparent to show not only the circuit board but four of the six lithium cells.CONS- Product listing shows capacity of 24,000mAh, while the device label and the box show a "rated capacity" of 13,200mAh.- The Shargeek underestimated time to charge itself: 31 minutes compared to the actual 50 minutes.- Instructions warn to use only in temperatures between 32 and 77 F. My house barely gets cool enough in summer time to use this power bank.- At $229, the "rated capacity" of 13,200mAh is extremely expensive. You can buy a deep cycle 12V, 100Ah marine battery at this price.- The Ampace 21700 lithium cells are available retail for $3.50 each. This power bank contains $21 worth of actual batteries. The electronics, programming and display are not negligible, but still, the device is pricey for the performance.- You can see the lithium cells, but they are not accessible. Especially since they are off-the shelf cells, it would be nice to have the option to replace or repurpose them if needed.
