INIU Power Bank with Built-in USB C Cable, 45W 10000mAh PD Fast Charging Portable Charger Type C, Smallest & Lightweight External Battery Pack for iPhone 16/15 Pro Galaxy S25 Google iPad Travel etcClimatePartner certified

I’ve bought a number of INIU power banks and this one is just as great as them. This power bank feels really well built, the integrated USB-C cable which can also be used as a handle is a nice featue. There is also a in/out USB-C port and a USB-A out port. I also like the pop out phone stand. Not something I will likely too often but it takes up not addition space so it’s a nice to have.The package is of the power bank is small but in my tests it has it’s rated capacity of 37Wh or more if you take into account a conversion rate with 20% losses. I was able to get out 32Wh while charging my laptop. (Please don’t go by mAh ratings as these can change depending on the voltage. It is very common to see people complain about worse capacity but will ignore their tester is reading a higher voltage than the battery voltage 3.7v which will lower the mAh value).My only complaint is the battery % display does not seem amazingly accurate. While I was testing I had 14% battery left when my laptop was fully charged. To get every last drop out I plugged it into another device. Within 10 seconds the percentage dropped to zero and the battery turned off. I would have expected there to be at least 4Wh left rather than pretty much nothing. It’s not uncommon for batteries to no display the remaining capacity accurately. But if you’re going to display a percentage rather than a number lights it needs to be better than this.Overall I’m very pleased with this power bank. It’s capacity is accurate or more than advertised. It has a high wattage output of 45W which is very good for a battery of this value.

INIU have tried to do something a little different with this power bank, there is an integrated USB-C cable - which is nothing new - however rather than stowing flush with the housing it can only be stowed as a loop which doubles as a lanyard to hang the power bank from ‘something’. Quite what INIU think anyone is going to hang this from I’m not entirely sure. The cable connector does slot in in such a way that it is unlikely to suddenly come loose and drop, but why would you risk hanging this on the outside of a bag or the like when it’s small enough to pop inside, where it’s also less likely to be nabbed by a passing thief or bumped into. The slot down the side could have been extended to give the option of either fully stowing the cable or creating a loop but unfortunately this wasn’t done which means the cable is always annoyingly trying to tangle up with other things.That said like the other INIU products I have tried recently this is a well made quality power bank. The charging speeds of up to 45W with a compatible device is particularly impressive given the relatively diminutive size, and although the power bank itself can ‘only’ be recharged at 27W that is still good.Priced at £29 at time of review this is fairly priced given the specs and the red colour makes a nice change to the usual black/grey/white of most power banks.

There is great variety of power banks with this capacity (10,000mAh), but this has a few features that make it stand out. The output capacity is detailed as 6,2000mAh hours (accounting for imperfect energy transfer). This is pretty typical, but not many manuafacturers are honest enough to state it.There is a built-in USB Type-C cable, which saves having to find and carry a separate charging cable. Stowed away, this provides a loop for carrying or hanging. I would have preferred to have the cable stowed in to the power bank housing, but that is a minor issue (and personal preference). This cable is bi-directional, so can be used to charge your devices, or to charge the power bank itself.Aside from the integrated cable, there is an additional USB Type-C port (also bi-directional), and a Type-A port (which is output only). All of this connectivity is on the end panel, where there is also the "wake up" button. This can be used to show the LED status display (a clear percentage indicator on the top panel, or to trigger charging if it doesn't start automatically.The charging power on this is excellent, and something I haven't seen on a power bank of this capacity before. Both the built-in cable, and the stand-alone Type-C port, support Power Delivery charging at up to 45W (15V/3A) - which is outstanding. This will charge my phone (25W), tablet (15W) and even my laptop (65W) - albeit that laptop charges below full speed. The Type-A port supports Quick Charge at up to 22.5W. All three ports can be used simultaneously, but of course the maximum 45W charging power is then shared across the three ports.Like many INIU power banks, this one has a little pull-out bracket, that acts allows the power bank to act as a stand for your phone. This is a great feature - for example, on a train journey you can watch a video while keeping your phone topped up. It is a simple but very welcome addition.This is an excellent power bank, portable and suitable for a couple of phone charges, or multiple top-ups, as well more demanding duties such as laptop charging. INIU is a brand that I trust, and this is another excellent product from them - backed by their three year, no-quibble warranty.
