INIU Power Bank, 65W 20000mAh Fast Charging Portable Charger with USB C Input & Output - (w/voucher & code) Sold by Topstar Getihu FBA

I have opposite experience, the quality seems to be very low, after months of use they take ages to charge up and the charge hold is disappointing. Even with the known losses of 30-35% of the nominal capacity, i doubt they hold the charge that they claim. I would stay away from this brand.

Return it.

You need USB-C to Lightening cable, buy a good brand like Anker or original Apple

It is a heavy power bank, and this is normal considering the specs/capacity. This stands out because it is 65w. Which is what people need for laptops mainly. If you look at 10k mah, I assume you need a power bank for your phone, not for a laptop. So, you can look at 15w-22.5w power banks and save some money. (edited)

But...do you need 65w? Do you have any devices charging at 65w? Maybe you've made the right choice.

Don't tell me. I lost the count, I'm at number 21 I think

Will it fast charge a pixel 8pro ?

Do you think it's a good deal for a 65w ?

Awesome

How much was the price difference? If we are comparing price is a big factor.

I have just checked now, still same price £18.99 after applying 35% voucher and redeem 15% promo code

you have a 3 year warranty! Claim it back.

How do you activate the warranty or use it ? Presumably not china for shipping ?

You need to add the coupon, before the payment screen: NWICVZGR

Why do you think this? The 65w INIU was posted quite a few times here at £23, so I don't think this is a pricing error.

Available again

I've got about 20. But only one close to this one specs. Lots of mine are obsolete. I doubt it you have many in your draw that charge a laptop.

Seems accurate to me. Learn about capacity

It depends on what devices you have. Most people don't need above 65w charge. I've got lots of devices, but none of them charge at above 65w. A more powerful powerbank will not charge faster if your device is manufactured for a lower wattage. It would charge your device at the 65w max if that what's your device supports. Some may suggest that a more powerful power bank is future proof. However, the technology moves on fast, and in a couple of years, what's high specs today, it may be obsolete. I have lots of devices I purchased thinking at future proof, and most of them are out of date now.
Yes, the 140w is higher capacity. Again, you have to think at the scenarios you use the power bank. Do you want a bigger capacity, which means a bulkier and heavier power bank? I carry with me a 5k mah power bank, as it is compact, lightweight and pocket friendly. But I have other powerbanks too, that I can use for other scenarios. If I go camping, I probably carry a larger capacity powerbank with me.
It also depends on what phone you have. Bear in mind that usually you buy higher wattage to use with laptops or other similar devices. For using it with the phone, most 18w-22.5w should tick the box. Don't get me wrong, a higher wattage will still charge the phone, but at the same speed as a lower wattage one. There are some phones supporting high wattage charge, but most of them don't.
You have to think if you need the power bank charged fast. The more capacity it has, the longer it takes to charge. Particularly if you use a 'standard' wall charger.
I'm not sure if the 140w has PPS. The 65w one had PPS. If you have a Samsung phone S20 or newer models, you need PPS for super fast charge. If the power bank does not have PPS, your phone would charge at a lower speed.
For me, a 65w 20k is a great deal at under £20. At more than double the price, the other one is not such a great deal. But as I said, it depends on what devices you have and on the scenarios when you use the power bank. Hope it helps!
