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

I honestly didn’t expect this level of quality at such an affordable price. Each power bank offers a real 10,600mAh capacity — enough to fully charge my smartphone about twice. The 2.4A fast charging via the USB-C port makes charging noticeably quicker and more efficient.The design is sleek and lightweight, making it perfect for travel or daily use. The additional USB-A ports are a great bonus, allowing me to charge multiple devices at once.What I also appreciate is the built-in safety system against overcharging and overvoltage, which gives me peace of mind during use.Honestly, this product combines high performance with great value. It's a smart investment for anyone in need of a reliable portable charger.

Good value, 2 for 1. Holds charge well. Has one USB C, one USB A and one micro-USB output. Compatible with fast charge depending on the wire used. Can charge iPhone, Samsung and Android phones as well as headphones and wireless keyboard with no issues. Has a good weight to it – doesn't feel too light nor too heavy.

I bought two one for myself and one for partner. One seems to hold more energy and charge items far quicker than the other. That said nothing work and have worked well for two months

Item came on time and in good condition. Went to charge it, only to find it was charged when it came.

Excellent product works well

This was a terrible decision to buy on my part and I wish I had just purchased a more expensive one from a reputable brand!I was really happy when they arrived, smallish and portable all ready for my holiday. I wanted to test them before hand, I made sure both battery packs were charged to 100% before using.Tested firstly with a quick charge of my phone and they seemed to work fine and I thought they'd do the job when on holiday.Thought to test them the second day. One battery pack was low so stuck it on charge - it took over 7 hours to get it back up to 4 bars! (Using a branded charger which charges my phone from 0 to 100% in an hour or so)Then tried to charge my phone from 0% overnight to give it a fair test. I left it plugged in all evening....6 hours later my phone had only charge to 62%The worst part is my phone no longer connects to my old branded charger and I'm going to have to take it into a phone shop to be looked at as I am unsure why it will no longer charge.It's probably going to end up costing me more money to get it fixed and I now have to wait 2 weeks to return and get a refund because I go on holiday in 2 days and a return isn't available before then!!Not at all happy.

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.

Good value twin pack. One for each of my girls. Charges well either from flat or just topping up
