2-Pack Power Bank Portable Charger 10600mAh, PowerBank 2.4A Fast Charging USB C Input and Output, for Smartphones and More

I stumbled upon this 2-pack of 10600mAh power banks while searching for a reliable charging solution for my devices, and I must say, they've exceeded my expectations!Compact Yet Powerful:Despite their slim profile (just 12mm thick) and lightweight design (229g), these power banks pack a punch. Each one can charge my iPhone X approximately 2.4 times, which is impressive for such a compact device.Versatile Charging Options:Equipped with both USB-C input and output, along with two USB-A ports, these chargers can handle multiple devices simultaneously. Whether it's my smartphone, AirPods, or fitness tracker, I can keep everything powered up on the go.Safety First:I appreciate the built-in safety features, including protection against over-voltage, over-charging, and short circuits. Plus, they're airline-approved, so I can travel without any worries.Great Value:At just £9.99 for two, this deal is unbeatable. The package includes two power banks, two USB-C charging cables, and a user manual. It's a comprehensive kit that's ready to use right out of the box.Final Thoughts:These power banks have become an essential part of my daily routine and travel gear. Their combination of portability, power, and safety features make them a must-have. Highly recommended!

Good quality, great size. Lightweight and portable. Battery lasts a very long time and is able to charge multiple devices at once. Design is sleek. Good value for money.

I was a tad disappointed as these twin power packs are not quite as advertised.Firstly, the advertised capacity is misleading as it's quoted at 3.7v rather than the normal working voltage of 5v.Secondly, these power packs do NOT fast charge as advertised - nor IMHO, do they appear to have that capability - my Samsung Galaxy Z Flip5 only charges at a lower rate - and only when using the USB-A output. If I try to use the USB-C connector, I get an error message to check the connection....That said, 2 power packs for less than £10 is remarkable value. I purchased these to recharge our drone lipo batteries while we are out. For that purpose, they work fine! They also fit easily into a backpack pocket.I have used them to charge my Flip5 when I have forgotten its power adapter. They work fine albeit rather slowly (say, overnight). From a fully charged power pack I get 2 full charges of my mobile. That's reasonable.So, it's horses for courses. For my purposes, these do their job. But, if you need fast charging of your mobile, look elsewhere 😉 🙄

Very affordable for the price of two. Very fast power bank. Light weight. Highly recommended

At £12.99 these are a bargain (they've since gone down to around £9 which is ridiculous).I purchased these 3 days ago, I've got them powering some fairy lights - as there are no plug sockets near enough to where they are - they've done a good 12 hours + so far on a full charge and neither bank has yet even lost 1 light of power (equivalent to 25%).I thought, for 12.99, I'd probably have to recharge them often... Boy, was I wrong. Well worth the money. Even just one bank at 12.99 is worth it, 2, we should be arrested for robbery the second we order them.Super light and portable if you need to take out, feel really solid, they use rapid charge to recharge as well, which is great. Super easy, super convenient, great product at a ridiculously good price.

Neither charger is working, received today and followed instructions. Charged for hours, the red one (which seems to be an issue for many) won't even stay on and the white one has very little charge after 4 hours of charging. Very disappointed, needed for this weekend but should have read the lower rating reviews and not just recent.

These certainly look smart, are pocket-sized and quite light in weight, are a very attractive low cost for 2 packs at a claimed 10,600mAh each, and boast a 22.5 watt fast-charging ability. But are they any good?Using USB-A Quick Charge 3.0 @ 18w and USB-C Power Delivery 20w and 100w ports they do indeed both charge fast and discharge up to the 22.5w (total) claimed where connected devices allow. A nice feature is that the first of the 4 capacity LEDs glows red when in fast charge mode - IN and OUT. Charging from standard USB-A chargers also worked well up to their own stated current limits.I cycled (fully charged and discharged) both packs several times to ensure the cells were exercised properly before using a Drok power meter with a 5v 2A fixed test load to measure capacity. I used both PD20w with “fast” leads and Standard USB-A ports. Here’s where both packs disappointed...Typically neither accepted more than 9,370mAh at 3.7v cell voltage (6,790mAh at USB 5.1v)... somewhat short on the 10,600mAh headline capacity. On discharge, both packs measured only 7,230mAh at cell voltage (5,250 @ USB 5.1v). So that's 1000+mAh short in claimed cell/stored energy, and a 2000+mAh energy loss in conversion... that's HUGE for a power bank of this modest size! In disbelief, I repeated these tests over several days, using a variety of chargers, leads, and charging speeds and without exception they consistently showed the same less than expected “available capacity” results (give or take a small margin).IMHO, I suspect it's down to a poorly designed BMS (Battery Management System) giving quite high losses in conversion efficiency, both at basic 5.1v as well as when bucking to higher voltage in PD mode - and maybe a generous headroom to protect the cell from being left in an overcharged/undercharged state over extended time (pouch cells tend to puff/bloat/rupture if left overcharged for too long, and self-discharge to an unrecoverable state if left empty... a high parasitic drain of app. 130mAh being measured every 24hrs). I haven't measured such losses in a good dozen other battery banks of similar - or even larger - capacity I've now tested.Another oddity was the 4 LED display showing charge remaining: On charge, these would sit at 1 LED flashing for well over half its capacity, then accelerate disproportionately to show all 4 LEDs lit as charge neared full. On discharge, the opposite - 4 LEDs lit for some time, down to three, then straight to none. That alone makes it difficult to depend on a power bank like this: Even if you can accept the less than claimed available power from the cell, the higher than reasonable conversion and parasitic losses, you can't reasonably gauge how much energy it's really holding.Maybe my packs were "duff"/oddities? Reading through a good number of other reviews here, a few have suspected a shortfall in available power, but couldn't quite put their finger on why...So while many will be looking at the headline 10,600mAh capacity – that’s an ideal cell capacity, not USB voltage – what you are getting is a usable 5,250mAh at USB voltage. That’s enough to fully charge a premium Samsung Galaxy S23 Android phone 1.8 times, S23 Ultra 1.4 times, or an iPhone 15 2.1 times, 15 Pro Max 1.6 times.
