Why my power bank provide fewer charges than expect?
Usually an external battery could supply 60%-70% power to other devices. Approximately 30-40% of the battery capacity is lost in circuit heat and voltage conversions. So a fully charged INIU 25000mAh B63 can offer 12000-14000 mAh to your devices.
How to calculate the possible number of charges?
ndustry-standard formula: (Rated capacity × 60%) ÷ Device battery capacity ≈ Number of Charges.
eg. (25,000mAh Powerbank × 0.6) ÷ 3877mAh iPhone15 battery ≈ 3.9 charges
How long does it take to 100% recharge?
It depends on the power of the wall charger used: 65W fast charger – 2 hrs, 45W fast charger – 3 hrs, 18W charger – 6 hrs
Does it support pass-through charging?
Yes, our power bank supports pass-through charging. You can charge both the power bank and connected devices simultaneously.
Is it allowed on airplanes?
Yes, our 25,000mAh power bank meets the regulations of TSA(Transportation Security Administration) for carring board(≤100wh≈27,027mAh).

Great quality. Used 25% to charge my phone from dead, which is great. I’ve recommended it to friends. It’s bigger than I expected but also better than I expected. Shows how much remains in the charger with the press of a button.
Using one of these to power a single board computer and 4 k monitor get about 4 hours + before recharge, and charges quick using a 100 watt pd charger,LCD display, quality finish.
Came with a short usb-c to usb-c cable and 49 per cent charge on its screen and took less than an hour with it’s maximum input 65 watt charger to get to 99 per cent. Love it. Works with my GPD Pocket 3 and can quickly charge my phone at the same time, so very pleased.
This charger is capable of charging a laptop and mobile phone at the same time. It charges quickly and has a Led display. It’s been made to last but is quite heavy. Great that it’s very powerful but okay to take abroad. Good value for money.
Power bank has just arrived and it appears to be a well made robust product. The LED screen easily shows you the current power level and the outputs are clearly marked by their respective power outputs.
Having used for a week or so now, I can confirm this powerbank has 72% efficiency. This means it can charge my S23 Ultra (5000 mAh) 3.6 times.
Also charges on 65 Watt charger in 2 hours.
Very happy customer. So happy, I have bought a second one. Between them they should last me years.
This little battery has completed what I need for remote work! It actually charges my laptop to full.
I have a thinkpad X1 for reference
Have used it for 1month now, and the full charge is showing 99% now (was 100% when I received it)
It’s also not too heavy! Basically same weight as my laptop charge
It has only 23766mAh. In the 2 days it is great. Let’s see along the way how good it is. I bought it to charge an MSI Prestige 16Studio laptop and a VIVO X80 PRO.
The power bank was intended as a backup for home and work laptops when on the move.
I was tempted to get a bigger unit as the work laptop is a 17 inch Dell CAD machine with high power demand, but read 100w was the limit for most airlines ref. carry on power banks.
Charging the home laptop was expected to be an easy task … the ability to charge the work laptop was more speculative given its size and power demands.
I’m happy to say the power bank has successfully charged both laptops. The work machine did not get a full charge, but the power bank was able to keep the machine running in the absence of a mains connection during some critical off-site events. It managed to keep the work laptop running and build charge when initially showing a critical battery status. I periodically use the power bank as an emergency fall back / it’s not an everyday item so the review is based on intermittent use.
Good value for money purchased and delivered on time – a solid recommendation as things stand.
Superb fast charging of my drone and backup batteries. The only consideration is the size which is larger than I thought it would be and you will need a fast usb charger to chare this otherwise it will take all night to charge. Would purchase again.
The power bank is now behaving better and is also almost matching my branded power bank product. It is still al ittle bit lower when charging batteries for some reason, thus the 4 stars.
However now it is working as described.
The device instructions recommend making sure you use this at least once every 6 months – I will make sure to do so!
