INIU Portable Charger, Smallest 20000mAh 22.5W Fast Charging Power Bank

Excellent power bank. I used this while travelling to Nigeria and it lasted really well. Doesn't discharge too easily and could fully charge my devices multiple times. It charges fast enough and it's super convenient that it comes with that small cord that acts as a holder. It's truly small and portable and could fit into my small purse, meaning I could carry it everywhere. Valuable purchase.

Solid and reliable! I really love how many times I can charge my phone off one full battery, at least 3! It can also charge my ipad off it twice and still charge my phone after. Very cute design, cable strap comes in handy. Bigger than the pictures suggest but still portable.

This is a great travel power bank for the price. It is a nice size and can fit in a pocket. The build quality and feel in your hand is very nice. It has multiple ports for charging. The display easy to read. Another feature I like is when you plug a device in it automatically starts charging. The built-in cable/hanger is amazing. The cord is a good quality, braided, strong. It also provides fst charging. We use it for phones and also Nintendo switches while on the go. I would highly recommend this for your next trip or outing.

Purchased this power bank (INIU B1-B5 20000mAh) due to seeing YouTube review of several PBs where reviewer took apart several PBs and showed that the batteries used in the PBs were actually rated far below the claimed capacities. INIU was one of few brands whose battery (in this case 20000mAh) label actually matched the advertised capacity. IOW, some brands that advertised 20000mAh capacity actually had batteries in them that were listed at 10000mAh etc. I used an old iPhone 7plus (with a 2900mAh battery) to charge from 50% back to 100% (or 1450mAh). The INIU B1-B5 went from 100% down to 86% (test was done three times with same results). Due to voltage conversion from the 3.7v battery to 5v USB output, the effective total capacity of the PB should be around (3.7/5)*20000 or 14800mAh. Since 14% of the PB was used, this amounts to 2072mAh. Since 2072 mAh of output from the PB was used to effectively charge 1450mAh of the phone battery, this amounts to a 70% charging efficiency. This means that I would get around 3.57 charges of my old iPhone 7plus out of this 20000mAh battery power bank. IIRC, I read somewhere that the expected efficiency of power banks should average around 80-85% due to conversion losses. At 70% loss, this power bank does not seem to be every efficient (although in my test, this may be due in part to the fact that the phone used is an old one). The positives: This power bank did charge my phone from 50% to 100 % in 1hr 57min which is pretty good given the iPhone 7plus is not fast charge (PD) capable. In my short time with the INIU, it seems to hold a charge well, did not heat up and did not heat up the phone while charging. It was also consistent in the charge times. The neutrals: While the thickness and weight of the unit does not lend itself to carry in a pocket while charging your phone (see specs on Amazon page), it is compact enough to easily carry in your carry on luggage as at a rated 74Wh it is well below the 100Wh limit imposed by the FAA and airlines. While it did underperform regarding capacity vs what it is advertised to be able to do, it was not as bad as some of the other power banks I tested, and came the closest to the advertised capacity as compared to some of the others I tested. The negatives: All power banks seem to use misleading specs in their advertising. Just because the power bank has a “20000mah” battery, does not mean that it will charge a device with, say a 4000mAh battery 5 times. Far from this due to various conversion losses etc. Also, I assume that these conversion losses can vary quite a bit between various power banks. While this power bank seems to not be very efficient, it met my needs (especially for the price). Unknowns: I have only just gotten this power bank and have only used it 4 times to charge my phone from 50% back to 100%. I anticipate using it primarily for travel. I have read reviews warning of battery pack swelling and failure etc over time. I have not had any problems with it so far but have used it for less than one week. So time will tell. In the meantime, my spouse also bought one as well so we will see.

The power bank works great! It recharges my iPhone and iPad quickly. The built in cable is very convenient. The only negative is its weight. I know the specifications provided its actual weight, it just didn’t click with me how that amount of weight would feel in my backpack and purse.

Works great and fast charges my phone. I did deplete the battery first before charging it to full as it does take a couple of hours to fully charge. The charging is great and it definitely met my expectation. I would totally recommend if you need a portal charge that is small enough to carry around with a fast charge ability.

I am very pleased with this battery pack! It is quite a nice small size so, it fits nicely into my purses/mini backpacks. I also absolutely love how much power it can hold and how fast it charges my many devices! (The usd-c to usd-c cable "handle" is also a very nice inclusion!)

This worked great. Seems to hold its charge for a long time. I love the attached USB-C cable in the leash, the digital display of remaining charge, the little LED light, and the 3 USB connectors.

Die INIU Powerbank macht insgesamt einen wirklich hochwertigen und modernen Eindruck. Das Design sieht sehr schick aus, vor allem in der beigen Farbe, und sie fühlt sich sauber verarbeitet an. Für 20.000mAh ist sie außerdem relativ kompakt und passt gut in Tasche oder Rucksack. Besonders praktisch finde ich das integrierte USB-C-Kabel, weil man unterwegs nicht extra ein Kabel mitnehmen muss. Allerdings wirkt dieses Kabel etwas dünn und nicht extrem robust, daher bin ich gespannt, wie langlebig es auf Dauer ist. Die Ladegeschwindigkeit ist im Alltag absolut ausreichend und das Display mit der Prozentanzeige ist sehr hilfreich. Man sieht sofort, wie viel Akku noch übrig ist. Ein kleiner Minuspunkt ist das Gewicht. Durch die Werbung und die kompakte Größe dachte ich zuerst, dass sie noch leichter und eher speziell für Reisen gemacht ist. Man merkt das Gewicht in der Tasche schon etwas. Für die Kapazität ist das zwar normal, trotzdem sollte man das wissen. Positiv: * sehr schönes und modernes Design * kompakt für 20.000mAh * integriertes Kabel sehr praktisch * gute Ladegeschwindigkeit * genaue Akkuanzeige Negativ: * etwas schwerer als erwartet * integriertes Kabel wirkt etwas dünn Insgesamt aber eine wirklich gute und stylische Powerbank für unterwegs, Reisen oder als Backup im Alltag.

Batterie achetée le 1er Février 2025. Ma batterie a explosé cette nuit vendredi 22 Août à la tête de mon lit. Je l’avais débranché vers 23h, elle était chargée à 90%, elle n’est jamais tombée ni choquée. ET ELLE A EXPLOSÉ à 6h ce matin sans aucune raison alors qu’elle n’était pas en charge. La fumée et le feux était incontrôlable. Fort heureusement la fenêtre de la chambre était ouverte et jai pu la jeter hors de la pièce. En 3 secondes beaucoup de dégâts. Jamais plus cette batterie. Tres dangereux Cette fois j’espère que ce commentaire apparaîtra… Je signale d’ailleurs ne pas avoir été contacté ni pour la garantie ni pour des explications, incroyable. Olivier

excelente, la usé para un viaje de 4 días y no la cargué ni una sola vez, me duró todo el viaje

Parfait, 10 journées d'utilisation en vacances et il fait très bien son job 👍🏼agréablement surprise par : rapidité de charge, sa taille,ses coloris, qualité du produit 👎🏼 Il est un peu lourd ⚖️

Bra storlek, hyfsad vikt för batterikapaciteten och jag har inte haft några problem med den trots en veckas lång fjälltur. Lägg den i en strumpa längst ned i sovsäcken bara så blir den inte för kall om natten.
