The power bank arrives with 1% (almost empty). Took about 5 hours to charge to 100% (full). When charging a laptop, initially the bank is depleted and drained quickly. Took about 10 minutes to drop from 100% to 85%. Then the rate slows down significantly. Took 7 minutes to drop from 85% to 84%. The climbing rate of my laptop feels similar with plugging into the wall. Overall I still recommend this product because it worked and fully charged my laptop.

The 64000mAh capacity is incredible because it can hold all four of my power banks in one, which is fantastic. I can practically charge the majority of my gadgets. This works perfectly with my laptop charger, which is USB enabled. You can use it for remote business, short road excursions, and camping.

I bought it in February and it worked well enough for three months. I checked the capacity when it arrived with a power meter after recharging and discharging fully, and it lined up with the rated capacity. The battery percentage shown is inaccurate and would either drop rapidly or stay on a particular number, but would eventually reach 1% and shut off. To fully recharge it, you have to keep charging after 100% until the screen turns off. My use case had it on a table that I needed power, but didn't want to run a power cord to, so it had an easy life and only moved for charging. I would run it down every 1-2 weeks recharging laptops and small electronics and immediately recharge it. Recently, it's been charging slower over 8 hours instead of 4 like when it was new. After the last charge, the screen does not turn off and the Type-C1 port does not output any power. Luckily, the C2 port is still working and I have drained it. I will not be recharging again in case the failure causes a fire. The included manual card states that there is a 12 month warranty, but there is no contact information anywhere. They don't even appear to have a website and only sell on third party sites. I had expected it to last a little longer. Update: I was contacted by Krisdonia Services through Amazon message and they sent a replacement unit. If you need warranty service, you can message them on their Amazon sellers page. The new unit has the same inaccurate battery percentage as the last one, which is fine for my use case.

If you’re only looking to charge your phone, I would recommend against this product. Instead, opt for the smaller 5000ah power banks that are easy to carry in your purse or pocket. These will be much more suitable for your needs. However, if you’re seeking a power bank that can be used off the grid to work on your laptop remotely or provide enough power to last through an emergency, this is the product for you. The 640000mAh capacity is impressive, and the 100W power delivery is excellent. To enhance its versatility, consider pairing this power bank with a solar charger. This will allow you to charge it anywhere you go. However, be aware that it weighs approximately 4 pounds, which is like carrying around a second laptop. Overall, the construction of this power bank is excellent. It’s heavy-duty and provides ample power. The only improvement I would suggest is adding an 3-prong outlet and making it IP4 or higher water-resistant. However, I didn’t deduct points for these features.
