POWER BANK 20000mAh PD20W Fast Charging USB C 22.5W Portable Charger Powerbank with LCD Display Battery Pack for Smartphones Smartwatch Travel Camping Outdoor etc

Fantastic battery pack for 10 it takes awhile to charge but charges phone up quickly

Unbelievable, should have got one sooner. Nice to handle, small and not much weight. Charges two at a time and still power left. Great stuff brill.

These are often sold under different brand names but share similar specs: Capacity: 20,000mAh Fast charging: PD 20W (USB-C), sometimes 22.5W via USB-A Ports: 1× USB-C + 1–2× USB-A Extras: LED display, slim design 👍 Pros 1. Big capacity (strong point) 20,000mAh = ~4–5 phone charges Example: iPhone 13 ≈ 4 charges 2. Fast enough for most phones 20W PD = good for iPhones and Android fast charging 22.5W USB-A often supports Huawei/Samsung fast modes 3. Cheap for what you get Many sell in the £10–£20 range → excellent value 4. USB-C input/output Can recharge itself faster (~5–6 hours with PD charger) 👎 Cons (Important) 1. “Generic brand” risk Quality varies a lot (battery cells, safety, durability) Some exaggerate specs (real usable capacity is lower) 2. Efficiency losses Real usable capacity ≈ 60–70% of 20,000mAh Normal, but worse on cheaper models 3. Build quality Plastic body, can feel cheap Buttons/screens may fail sooner 4. Not great for laptops 20W is NOT enough for most laptops Only good for phones, earbuds, tablets

I bought this power bank as a back up whilst on holiday. It is nice and sleek though a little heavy. The lead is shorter than expected but does the job. Overall good value for money

Fantastic power bank. Really happy with it. Charges well, holds it's charge. Really pleased we got it. Size is good fits in a pocket. Easy to take away or in the car.

Great little power bank for the price. It can reach fast charge speeds but not super fast charge, although that's not really an issue if I'm honest. Great for long journeys and flights, which is why I bought it. Can't fault it. The charge in it seems to last for a decent amount of time and can charge a phone to full a few times on one whole charge.

// Edit: I gave this 2 stars originally. See below. // This item is listed as "20,000 mAh" on this page, on the packaging it arrives in, and on the plastic case itself. Unfortunately, this is a very intentional lie. If you crack open the plastic case, you'll find a single lithium-polymer pouch cell, with all the usual tech & spec stuff printed onto the pouch from the factory -- except there is NO information printed on it regarding capacity, because it has been rubbed off. The weight & dimensions of the cell indicate a capacity of around 8000 - 10000 mAh, which I knew before even opening it up, precisely because of the weight & dimensions of the power pack once I had it in my hands. It is a fundamental fact about battery chemistry that weight & size dictate capacity. There is no magical way around this - you can't double the capacity of a lithium cell without approx doubling the weight & size. I have bought and disassembled dozens and dozens of these portable power charger packs and the vast majority of them are dishonest about capacity. Often you're only getting around 2/3 of the advertised capacity, and often it's just because of poor quality lithium pouches -- but at least the claimed capacity tends to agree with the design capacity of the cells inside. This product, however, simply claims to have double the capacity of what's actually inside. Having said all that though, it's still not bad for a tenner, I suppose. --------- EDIT --------- Good results! After some analysis of the cell, including a few discharge cycles through a battery capacity tester, the results are definitive. The power pack design capacity is 10,000mAh / 37Wh, which it easily delivered under a 2.5A constant load. The usable energy measured about 38.2Wh. This is in the top 5% of all the 10,000mAh cells I've analysed from products within this market segment. The seller should amend the product info: it's a true 10,000mAh portable power cell. Combined with the PD/QC functionality provided, it's a bloody good deal for the price I paid (£9.99).

Ok and very handy. Not much battery life so you might only get one good charge out of it but brilliant in an emergency
