Portable Charger USB C RAVPower 20000mAh Power Bank 60W PD3.0 Fast Charging Compact Battery Pack Laptop Charger for MacBook Pro Dell XPS iPad Pro iPhone 12 Pro Mini Switch (Charger Not Included)

I have a Dell XPS 7390 (late 2019) laptop and this battery pack was able to keep it running for almost exactly six hours.The first thing I did was fully charge the power bank using my Dell XPS 45W charger, which successfully charged at the maximum 30W input this power bank allows for. I then let the battery pack sit for an hour.My particular laptop has the top-end i7 CPU, UHD screen, 16GB of RAM, and a 1TB SSD. It's basically the top XPS 13 7390 model. I was running screen brightness at 60%, adaptive brightness disabled, and most power-saving features disabled. The fans were idle during the entire test.I used an in-line power meter to measure the power.The Dell XPS 7390 comes with a 45W power supply, and the laptop may pull that much power under heavy load, but most of the time it's using 10W at idle, boosting up to 20W during heavy user activity, and only occasionally getting up into the 35-45W range when all six-cores/twelve-threads are being used. For the six hours that my laptop ran I had a music stream over WiFi and most of my activity was mousing around, reading in my web browser, and doing email. The average power usage for this test was about 12W, and the six CPUs were running in the 10-15% range most of the time. This usage pattern was pretty average for my daily usage pattern, but should be considered an ideal scenario because it isn't very intensive.I noticed the power pack's last blue LED blinking at approximately 5:40 into the test, and the battery finally gave up and shut off after 5:59. My power meter says we got 3084mAh (at 20V) and 61962mWh.RAVpower says their power bank is rated at 20000mAh. What they don't tell you is that this is internal capacity instead of what you will actually get out of it. These lithium batteries run at 3.7V, and 3.7V * 20000mAh is 74000mWh. No power pack is going to convert 3.7V to the 20V my laptop runs at with perfect efficiency, so we must expect some loss. In our case here today, we divide 61962mWh by 74000mWh to find out our efficiency was about 84%. I've read online that a 90% conversion rate is reasonable, but I'm under the impression that's at 5V and my test was at 20V.Is this result good or bad? I don't know. We would have to compare it with other models. Discharge efficiency is probably affected by environmental temperature and the discharge voltage and amperage.The pack gets a little bit warm on one side while discharging, but not hot.The blue power meter LEDs are nicely diffused, not too bright, and are off during discharge.My one complaint is that I wish there was some way to read battery health and charge data over the USB connection. Having only the four LEDs to evaluate charge percentage is pretty rough. I'd also like to see metrics such as total number of discharges, time left to charge, and things like that.

Yet another fantastic RavPower power bank. Purchased this one because its 60W PD output is great for putting in my laptop bag and charging my laptop without having to find a wall outlet, etc.I've also attached some protocol polls from a usb monitor that I frequently use. NOT IN ORDER, - These shots represent (while the monitor is being independently powered by a wall outlet so as not to "contaminate" the detection results)1) being directly plugged into the power bank's usb-a slot2) being connected to the power back via a usb-a to micro-usb cable3) being connected to the power bank via a usb-c to usb-c cable with an e-marker IC4) being connected via a usb-a (on the power bank end) to usb-c (connecting into the monitor itself) like a Nintendo Switch controller cable, etc. These cables can also trigger Samsung AFC functionality, so I wanted to show that it was indeed triggering that as an available mode on the power bank.Hope this review was helpful! <3 u

Bought this battery as a backup to my Macbook Pro. Although it is rated at 60Ws, it is unable to consistently charge. It cycles through charging and not charging every 10 seconds. I thought it was just a defective unit, requested and exchange and same thing with the replacement. Will be returning this POS. Pretty disappointing because I have other RavPower products before and have been great in the past.Edit**RAVPower reached out and offered an upgraded version of this unit and it now works in charging my 16" Macbook Pro. Great product and company. Glad to know that it was originally only a faulty unit.

Be careful. You can't just plug this into your usb wall charger or computer and charge it. It only comes with a usb-c to usb-c connection.I may update my review after I get it charged.Update: Changed from 2 to 5 stars.Company was very responsive. I was caught off guard because I was starting an out-of-town convention and needed the battery charger, but had no way to handle a usb-c connection. After reading my review, they reached out to ask if they could send me a wall plug-in. So far, the wall charger and the portable battery work great.

I was looking for a power bank that can not only recharge two batteries in the grip of my Canon R5 camera but also provide the power source via USB-C connection for a long period of shooting the camera well beyond what two batteries in the grip can provide. This particular 60W power bank by RavPower does exactly that. Now, when I'm out in the field shooting birds and wildlife for hours or working on a time lapse project, I don't have to worry about the camera running out of power for the required duration. When connected via USB-C, the camera draws the power from the power bank and not the batteries in the grip. This is my second power bank by RavPower, the first one, RavPower RP-PB058, has been used for charging my smartphone and other devices since 2017 without any sign of quality deterioration. When I needed a power bank strictly dedicated to power deliver my camera, I didn't hesitate to go with another by RavPower because of the long term quality.

This is a simple product with a simple function, so you think it would be easy for manufacturers to get it right. But alas, it seems difficult for many. These guys seem to have gotten it right!It is small, but in a good way. The capacity obviously has a ton to do with the size, but for me, the size is perfect. I can work remotely away from a power outlet for an entire day with my MB Air and this will get me through the entirely of the day np. That is why I bought it, so the size for me is great. I can also keep my iPhone juiced a little as well.Which brings me to the output It works great to power my Macbook. Again, that is why I bought it, but a small form-factor like this that can power my computer is awesome. And it charges pretty fast. I have not measured the exact output, but the 60w advertisement seems to be accurate.

This works for charging a HP Probook 440 G7 via USB C, the only minor snag is that it doesn't work immediately. Getting it to start charging seems to require plugging it in, unplugging it and plugging it back in several times before the power bank starts charging the laptop rather than the laptop charging the power bank. Once the laptop starts charging from it though it works just fine, and charges the laptop just as fast as the wall charger. You can get at least one full charge of this laptop out of it, while also using the laptop, plus charging a phone at the sametime.

Positives: For the price, this power bank is arguably the best value. With 60W charging through Type-C, charging laptops and phones is a lot faster than other power banks. The build quality feels good, the unit is quite small and light compared to flagship power banks, and the LED indicators are such a nice quality-of-life improvement that I hope we start seeing these on other power banks as well. The lengthy warranty gives peace of mind and the large capacity means that I've basically never run out of juice on my phone. I will note that I considered the 25600 and 26800 mAh models and found the difference in charge to be noticeable but not significant enough to warrant spending double the price. At that point, I suggest just buying two of these.Negatives: It's a little slippery, which isn't a problem until your SO drops this repeatedly. I've never found it slippery but for dry hands, YMMV. The dual port design is also a little limiting. The most I would ever need is probably 4 ports, but having 3 would have been quite nice. At this price point though and with 60W PD, I can't really complain.Conclusion: If you need a good quality large size battery bank by a reputable manufacturer but aren't willing to spend the near $150-200 prices of flagship power banks, this would be my choice. The small size, decent construction, and amazing power delivery make this, in my opinion, THE best budget power bank to buy.

One of the best powerbanks on the market, well made. I use it to charge my phone aswell as dell xps 15. Only comes with a usb-c cable, no charger or case

Got this to run a Raspberry Pi4 and charge devices on the go. I’m a short time it’s proven it’s worth. Would buy these againFast shipping.

Could use more USB ports but it's a solid battery and portable.
