INIU Portable Charger Ultra Slim 45W Fast Charging with Attached USB C Cable Flight-Safe 10000mAh PD Power Bank

This battery is small and convenient, powerful, and fast to both charge itself, and to charge your phone on USB-C. It also has a fast USB-A port and a second in/out USB-C port. You can charge three things with it simultaneously. The feature I didn't think I would care about was its little wrist-strap USB-C cable -- but I was wrong. It's just a few inches long, and it's securely but loosely bound to the battery, with a plastic holder protecting the two USB-C plugs. It's always there, yet it adds minimal volume, and it won't break a plug or a jack when I jam the battery into a pocket or purse. It's very convenient to have it there. After a few months, the woven cord is starting to fray at one end. I've tried slowing the damage with some Liquid Bandage and we'll see how it goes. Read more

This is a great power bank for the money. The form factor is compact. The soft-touch exterior resists fingerprints and likely will show scuffs far less than a glossy surface. The USB-C cable/lanyard design is well executed. You can actually dangle the unit from the lanyard without risk of disengaging (although I wouldn't be too aggressive out of caution). I used a USB meter to validate the charging specs. The device works as intended. It charges at a full 27W if you use a 30W charger, for example. It does indeed deliver full power to devices depending on their specs. For example, my iPhone 16 Pro charges at about 25W when below 20%. Obviously it will charge at reduced power when over 80% by design, and tickle charge over 90%. I don't own an Android device to test the 45W charging potential, but other reviews here confirm that works. I did charge my MacBook 12-inch which takes 30W when the battery is low and this power bank did provide that level of power. Note that the MacBook does require more than 15V (the maximum voltage rail for this power bank), so a laptop that requires 20V (many do) will not see the same results. Pass through charging works for this power bank as well. There has been some misreported information on this feature, however. Some people have reported that the power bank will only see ~7W when charging with another device attached for charging, and that device only sees ~4W. This power bank is not as intelligent as perhaps it could be, so the order in which you plug in the cables matters to the charging power. If you plug in the bank to a 30W charger, it will show 27W charing power. If you then take an iPhone or iPad, for example, plug the cable into it and then plug the other end into the power bank, the charging power to the bank will drop to ~15W and the device will charge at full power (which depends on its state of charge as described above). For example, it charges an iPad at 60% battery at 9W with the bank charging at 15W. Any empty iPhone 16 will charge at 22W with the bank charging at 15W. It appears the bank charing power is capped 15W. If you plug in a cable with the bank already charging, the cable resistance will tank the bank charging power to ~7W and if you then plug in a device it might get only ~4W. Unplug the device and reconnect it and it will receive full power for its state of charge and the bank will again see 15W. I hope this helps people who need pass through charging. I don't recommend doing this often, however, since it generates heat and is not the preferred charing scenario. It does come in handy when needed, however. Read more

I absolutely love this portable charger! It’s incredibly slim and lightweight, making it super easy to toss in the bag or pocket for travel or everyday carry. The 45W fast charging really delivers — it gives my phone a fast, reliable boost when I need it most and keeps other devices topped up too. What I appreciate most is the built-in USB-C cable — no hunting for cords when I’m in a rush, and it even doubles as a lanyard so I don’t misplace it. The 10,000 mAh capacity is plenty for multiple phone charges on a weekend trip or long day out. Read more

This was a game changer on my trip to Japan. I wouldn't travel (to Japan especially) without it. It held a charge really well and was a portable size. It was a little heavier than I expected but it's well worth it. I liked that the lights showed you how much charge is left/how much charge has been gained as its charging. Being a pet lover I also appreciated the cute paw print detail. For my phone, using a super fast charging cord, I could get 100% charge with only using 1/4 or so of the charger's battery when my phone was down to 20% or less. The black color is sleek and I think it's pretty durable because I dropped it a couple times and it seems fine. Read more

I learned on my recent trip that an even smaller compact charger (different company) was no longer working correctly. I searched the net for a new one with compact as my main goal. This INIU product was given high review for best small charger. It is effective although it weighs much more than my last one which was so small that it looked like a credit card. So I do feel it in my pocket but not too burdensome. It has three ports including a USB and the lanyard turns into a cable for the "C" ends on each side. It charged my phone easily enough and I like the "paw" light showing the amount of charge left. My only complaint aside from the weight is that it took hours to fully recharge itself. I think that was far too long. Btw, it comes in different colors which is a nice benefit. Oh and the price was excellent. Read more

INIU for the win again! I have purchased several INIU products in the past and this portable charger does not disappoint. It is slim and lightweight which is a plus for storing in my purse or pocket. The charging cord is made from a durable material, I’ve trying tugging at it and stretching it and it holds up very well. I can get about two full and fast charges on my iPhone 16. This little charger is a game changer! I bought another for my husband who is always trying to take mine and he loves it too. Read more

Perfect travel power bank. The slim profile and light weight makes an easy carry in pocket or a bag. I've been using this to charge my Fold7 and it works well. I have also used it to power my Fireboard Drive 2 to run my smoker and it worked flawlessly to power it for 5 hours. Current price and quality makes this a no-brainer. If you are looking for a great Power bank that support PD quick charge, I highly recommend this product. Read more
