INIU 140W 25000mAh Portable Charger for Laptop & Phone, Mini Power Bank with PD QC Fast Charging (USB-C in/Out) - High Capacity Electronics Battery Pack for iPad, Samsung, Travel, CampingClimatePartner certified

Excellent powerbank!Charges devices faster than wall chargers.I use it mainly to power my portable studio light Godox Ml100bi and can power it to 100%!!!Very compact size (quite slim for it's specs), has some weight but that's expected considering the 140w.I also contacted the manufacturer to ask some questions related to my nitpicking habit and the customer service was absolutely superb.I'm very impressed👌

I have a SteamDeck and I like taking it into work and playing it during the commute but if I have had to manage the power consumption very caefully to get a full 3 hour run which means I can't play some CPU heavy games.This unit delivers a serious punch at 140W+, the SteamDeck only needs a fraction of this and I've been able to get 5-6 hours of gaming out of my SteamDeck using this unit. I use the Steam Deck charger ( 45W ) to charge this battery pack and it does it in about 2 hours from 0-100.Something unexpected I use this with my drones, I have a DJI Mini4 with 3 batterys and taking this battery pack out for the day I can easily get 2-3 hours of flight time with this unit delivering a full drone battery charge in around 25 mins, which means I'm flying, changing and charging until the last bit of power has gone from all the batteries and this unit.I've even been able to charge the drone batteries, the DJI RC2 remote AND a mobile phone all at the same time thanks to the multiple level sockets on the unit and using splitter leads.It's a little heavy to carry around but the punch it delivers is phenomenal and it's paid for itself already by way of how much freedom and usage I'm getting from my devices.

Was a lovely piece of kit. I’m a big fan of INIU equipment. I got this to charge drone equipment out on the road. I have their 100w banks and they are great. I got this because I thought I’d go for a bit more power as it will get me in the air quicker. I loved the display telling me what wattage I was getting and how long it would last, nice touch. I ended up returning it due to it charging at the same rate as my 100w banks because of the equipment I was charging and not because of the power bank.The batteries in my drones etc are smart batteries so will allow the max charge they will allow and constantly monitor themselves. Their 100w small power banks are amazing and work so well.This is a lovely item, especially with the display telling you what the bank is doing and how long it has power left.INIU have been brilliant with their customer service with me and if you’re in the unlikely position of an issue they deal with any issues quickly and effectively. Highly recommended equipment and company. I also use their 100w/240w cables as well which are brilliant.

The first time I used the battery pack I noticed that the power drain was much quicker than expected. Finally with the battery sitting at 31% the pack refused to charge any longer and would just flash the percentage at me.Both of these issues are mentioned across various reviews here.This likely relates to poor battery calibration from the factory. But it can be seemingly fixed at home by completely charging/discharging the pack a few times to correctly calibrate the charging circuit.To test this, I decided to charge it to full, and then leave a game running on my fully charged steam deck using 22w of power from the battery pack to see if the issue returned.The pack remained at 100% for a VERY long time even though it was clearly discharging, then began to reduce normally. On this second charge/discharge cycle the battery pack lasted significantly longer than the first time at just over 4 hours, and stopped charging at 11%. This is more in line with what I expected from the pack.On the third attempt, I used it to revive my completely dead steam deck using slightly more power at 25-30w. The battery remained at 100% for over 40 minutes before the percentage started decreasing. It lasted a total of about 5 hours, and then stopped charging at 0%.It's likely the circuit is now able to determine the upper and lower limits of the battery inside.As for the rest of my impressions; I use this to travel on flights with my steam deck, and have not had any concerns from airport security when my baggage is checked (as expected as its within the 100w hour limit for most airlines). It's heavy, but that's the nature of the battery tech inside and cannot be changed.I appreciate the shape of the pack being flatter than other battery packs which are more cuboid in shape, as the slimmer profile means I can easily keep this on the side pocket of my backpack for quick access. I love the feel of the pack, but it is unfortunately easily scratched and has already suffered deep scratches from just one journey. It comes with a protective sock to keep it in which will help the important text stay protected (important if you want to take this on a flight).The stats on the advanced mode are incredibly useful, actually. I've found the time remaining to be a good estimate based on the above tests, now that the battery is correctly calibrated.Overall, knocking off one star as calibrating the pack to obtain the correct capacity is a faff. But the overall look, design and functionality of the pack is excellent.There's very few options that provide the wattage, capacity and design at this price point and with consideration for airline allowances, so for that reason I recommend it.

Great charger if you need to power a laptop on the go. Can charge phones etc too. Quite heavy but to be expected from something like this. I saw one my brother had and thought I must get one myself. No regrets in doing so
