i got this a few days ago after some pretty good reviews, but when i went to go plug it into my laptop, it charged for 20 minutes before going straight to 0 batteries.... and in that time only 20% got charged. i don't mind the bulkiness of the bank and love the phone stand feature, but the charging only seems to work well for my phone and dies out way too quickly when using it for my laptop.benefits:- phone stand feature- somewhat easy/followable directions- two different cables (usb-c to usb-c and usb-c to usb)- charging power is decent- charges phone wellcons:- battery life drains out way too quickly- usb-c - usb cable did not seem to charge my laptop but the usb-c to usb-c cable does- bulky (fine with me but could impose an issue for those who prefer more portable power banks)

purchased on 01-17-2024 for a net of $29.99. ***$59.98 - $20.99 (35% discount coupon) - $9.00 (promotion discount) = $29.99***i own and use some of iniu's other products: 10,000 mah and 20,000 mah power banks, 45w ac charger, dc car charger, and usb-c to usb-c 100w cables.i had been pleased with the performance of their products...until i got this.my immediate reaction after removing this 25,000 mah power bank was that it's much heavier and bulkier than the 20,000 mah bank.- weight: 17.21 oz vs 12.23 oz- thickness: 1 1/4 vs 1- length: 5 5/8” vs 5 1/8”- width: 3 vs 2 3/4”next, i notice that the led battery level indicator is so much dimmer than the other banks. more on this later...i go on to charge the bank. no issue.i test how many times it charges my phone compared to the 20,000 mah bank. with phone battery at 3%, i connect it to the 25,000 mah bank.over the course of 3 days, i've charged my phone 3 times. the battery indicator on the bank shows 11% remaining. at this point, it's not doing that much better than the 20,000 mah bank.so, i start the fourth charge. this is when it gets really squirrelly!after a few minutes, i notice that there was a precipitous drop to the bank battery. it went from 11% to 7% without a commensurate rise of the phone battery.then, after another few minutes, i look at my phone and noticed that its battery level decreased. you guessed it. the power bank was now reverse-charging! the bank was sucking juice from the phone.yep, it was a whiskey tango foxtrot moment.when i connected this to the charger to recharge, the lcd indicator went double-vision for a few seconds before it settled on 35% as the battery level. whiskey tango foxtrot ii.how could the starting point be 35% when it was less than 10% last night?obviously, it's defective. being returned.back to the dim indicator light... before i did the charging test and discovered that the bank is defective, i sent an email to iniu inquiring about the light and its level of brightness. i received an immediate automated response indicating that i will be contacted within 24 hours to address my query. well, it's been 3 days, and all i've received was some pro-forma response asking for a copy of the receipt. nothing that directly addresses my question. whiskey tango foxtrot iii.***01-28-2024 update***to make certain i wasn't wrong, i repeated the above test. in a nutshell, same result.with the power bank at 100%, i charged my phone under the same condition as my first round---start with phone battery at 3%. this time, after 3 phone charges, the bank showed 19% remaining (first round showed 11%).i start the fourth charge. since the bank is at 19%, the phone *should* charge to @ 75% +/-. well, after a bit, the precipitous dip repeated, followed by the reverse-charge.on both tests, the reverse-charge occurred at around the 7% mark on the power bank.btw, still haven't heard from iniu.

the device is too heavy to travel with for starters. when i took it out of the box i was never successful at getting the unit at 100% charged. it would not charge past 68% after 24 hours. it is too bulky as well and i was very disappointed. nice charger time if you get it working and want to lug it around. this was a hard pass for me.
