INIU Power Bank, 25000mAh 100W High Capacity USB C Laptop & Phone Portable Charger, Fast Charging Flight Cruise Ship Travel Essential Mini Battery Pack for College Students Travelers Boys Girls, Red

This has to be the best buying decision I've made. This is a beast! Very useful, very reliable. You can carry it on an airplane as well. Massive battery storage, can charge your phone, laptop, and other devices. It has fast charing, 40% to 95% within 30 minutes! This is a must have if you are traveling. It takes a lot of time to charge the power bank. Value for money! You will not regret buying this Although it does come with a cable, I would suggest buying a few cables from the brand as well along with it.

There is nothing light about this power bank (about 500g) which is what you would expect with a big battery (multiple batteries inside). If it was light then it wouldn't be able to deliver the power. I use my phone as a mobile hotspot for my tablet when I work outside and needed something to charge both on days when I use the devices heavily. It managed to fast charge my phone and charge my tablet simultaneously. My old power bank simply couldn't fast charge anything and couldn't deliver enough power to charge the tablet at all and therefore I couldn't work all day without finding an AC adapter. This one looks and feels quality. Many other power banks (cheaper) either lie about their capacity or simply disappoint - this one does exactly what it says it will. Very pleased that I invested in it. Best power bank I have had. Lower power devices (ear buds etc) will need to be charged from the 18w port I found, therefore you may need to carry 2 cables (USB-A and USB-A). The bank comes with a short USB-C cable so you may need a USB-A to USB-C cable for some devices. Make sure that you use good cables to fast charge devices not cheap cables. [UPDATE] I have bought a USB-C to 5.5x2.5mm barrell adapter so that I can run my Gigabyte G5 gaming laptop. I also bought a USB-C cable that shows the charge in watts and can graph my laptop battery being charged and discharged. The laptop thinks the power bank is an ac adapter and therefore can charge the laptop battery at a rate of about 14 watts and run the laptop doing normal work (web browser and watching Amazon Prime video). The power needed to do this varies between 33 watts and 59 watts depending on what the laptop is doing. Power bank works great. I then got the GPU running and played Halo - the power bank delivered 110 watts (and even 114 watts momentaraly). The laptop wanted more power than this and so behaved as though the power plug was being plugged in and out every 5 to 20 seconds, when this happened the laptop is switching between its own battery and the power bank. The power bank therefore is working perfectly! If I stop using the GPU to play the game power usage returns back to 35 watts approx. During my tests the power bank ran the laptop for approx 45 minutes, charged the laptop from 25% to 40% and powered the laptop while in use and by the time I wrote this line the power bank was only down to 65%. The powerbank can deliver 110 watts momentarily and will sustain 100watts (I haven't found a way to demand 100 watts continually yet). It does deliver what it says it can. The photo shows the laptop playing a video and graphing the laptop battery charge and discharge while I tested. Just to show that I did test it. The blue part of the graph shows me trying to disharge the battery the red line shows when the power bank was running the laptop and charging the laptop. It shows at that moment the power bank was delivering 51 watts to the laptop and for my tests which lasted about 45 minutes the power bank only discharged down to 73%. While the GPU was demanding a lot of power it also shows that the laptop wasn't being charged and as soon as I stopped playing Halo charging resumed at 14 watts. Bottom line is this is a great power bank and works as advertised. Well pleased.

Decent power bank but quite chunky i knew it would be bigger from the pictures but it’s quite heavy aswell feels like your carrying a brick in your pocket. That being said if you keep it in a backpack I’d say it’s a really good power bank battery life is good charging speed is good has both usb A and C ports so good functionality. INIU make the best power banks I got another smaller one from them which I carry in my pocket and it charges my phone twice which is more the enough for my work day as a delivery driver.

A solidly built, fast-changing piece of kit that I carry when travelling. It charges my Samsung Z Fold faster than my Samsung mains charger and powers my laptop. Chunky and a little heavy but I'm fine with this given it's excellent performance. And it can be taken onboard flights (the wattage is shown on the back to show airport security it's 100w if the need arises).

Bought the power bank as it was on price cut and I need one to replace a faulty one. I was surprised to find a thick power bank when I opened the package. It was at least 0.25 to 0.5 inch thicker than those pictures in the product description and it was quite heavy too (see picture). Anyway, I bought it to power my laptop computer and it does its job. When I recharged it after a couple of cycles of use, it went dead as you can see in the video. The screen kept on blinking and it couldn't charge. I googled the issue and found restarting the power is one of the solutions. And so I did. It's working fine now but I don't know if the same problem would happen again. The product comes with a slider and it was a mobile phone stand indeed. It's a thoughtful design (see pictures). It also comes with a short USB c cable and cheap cloth bag for storage. Overall, I'm not impressed with the pictures at the description of the product not matching the exact product, which gives people a wrong impression of the thickness of the power bank. I'm also worried about the reliability of the product. Therefore I took one star off each. Other than that, the power bank works fine after two months of use. I think there are other similar products in the market for consideration and I will go for other brands should I need one in the future. [Added after customer service contacted] After I posted the above review, the after-sales customer service of Amazon send a letter to me and offered me a brand new replacement of the power bank with 3 years warranty. I'm impressed with the gesture and so I took the offer as the previous one has issue there. I might need one as backup in case the previous one fails again. I'm impressed with the customer service but not the product and I have to be true to myself. Still, the picture the customer service used in the letter is not a genuine reflection of the actual thickness of the product, which lured me into purchasing the product (it is at least 1/4 inch thicker than the picture). Overall, I am very impressed with the quality of the after-sales service but not so much for the product. I do not want to mislead others in this review for the power bank and I'm sorry that I have to maintain the same review rating for the product. Revised October 2024 After a year's of usage, I have decided to revise my previous review and give it a 4 stars rating for its power and endurance. It still works as well as it was a year ago and the reliability issue seems to be gone as time goes by. It can charge my phones multiple times before I have to recharge the power bank. It's not a power bank that you can carry around in your clothes pocket but considering the high output it provides and the power bank is a product made a year ago, it's good for what it supposed to do.

INIU are great for chargers & this one is super too. Battery life is very good, easy to use. Great quality. Feels good to hold. Charges well.

Excellent product. Highly recommended.

急充電も良く長持ち。耐久性もあり良い商品。

Piccola ma potente, ricarica velocemente lo smartphone, e si ricarica essa stessa molto velocemente: un ottimo prodotto e un ottimo acquisto: la consiglio a tutti!!

小型で25,000ｍA 入出力100W 出力時の最大容量は 16,000ｍAh と、 裏側に表記があります（写真添付） このメーカー（INIU）の商品は、過去に購入していて、 （20,000ｍA と 10,000ｍA） お気に入りのメーカーです。 大きさは確かに、 縦・横 のサイズは小型（小さい）ですが、 （アイフォン 4.7インチよりも縦は短い） その代わり、厚みが有るので、要注意です。 （一般的なモバイルバッテリーよりも【明らかに】厚いです） 重さも25,000ｍAなので、当然、それなりに重いです。 バッテリー本体への充電は、C1 。 C2では充電不可なので要注意（本体をよく見ると書いてありましたｗ）。 リチウム電池を長期間保存する時は、半分くらいの充電状態で、 保管することが良いと、以前何処かで読んだ記憶がありますが、 到着時のバッテリー残量は 51％ で、バッチリです＾＾。 全てのモバイルバッテリーの情報に目を通していませんが、 私の知る限り 【3年保証】 を記載しているのは、 こちらのメーカー（INIU）だけだと思います？？。 それだけ、自社製品に対して自身を持っている、と言う事かな？。 以前購入した理由も、【3年保証】が大きな理由でした。 （まだ壊れていません） ☆バッテリー本体への充電に関して☆ 充電入力（出力も）が100Wとの事ですが、 45Wのアダプターと65Wのアダプターで充電した時の数値は、 44.05W 62.63W となりました。 （100Wのアダプターは持っていない為、未確認） （写真添付） 充電時間は、1時間40分（確か？65WのADで充電？） 以前PDアダプターを持っておらず、 ５V2AのADで、20,000ｍAのバッテリーを充電すると、 確か・・・10時間くらい？？掛かっていた記憶があるので それを考えると、本当に早くなったなぁ〜、 スマホを充電するのと変わらないなぁ〜と言う感想です。 充電容量に関して、 残量４％から100％まで（96％分）充電した時のW数は90Wh（写真添付） 90Wh=90,000ｍWｈ 90,000÷96×100＝93,750ｍWh（100％換算時） 93,750ｍWh÷3.7V＝25,338ｍA となるので、 25,000ｍAの表記通りです。 ？？私の計算、合ってますか？？正直、不安（笑）。 違っていたら、お許しください（笑）。 私は、上記計算で、勝手に納得していますが（笑）。 ☆ノートPCへの給電に関して☆ 私のノートPCの充電は 45W入力 です。 （普段はAnker社の65Wアダプターで充電しています） メーカーの商品ページを見たのですが、 バッテリー容量の表記は見つかりませんでした、残念。 先ずは65Wアダプターを使用して、 残量20％から100％まで（80％分）充電した所、 充電W数は 32,256ｍW。 次に本バッテリーで19％から100％まで（81％分充電） （同じ20％から、にしたかったのですが、 うっかりしてｗ、気がついたら19％になっていました！！） 充電のW数は 33,025ｍW でした。 （写真添付） ただ・・・ケーブル他の相性が関係している為か？？ 65Wアダプターで充電するときには、40Wを超えるW数で、 充電するのですが、やや小さく、35.98Wでした（写真添付） ノートPCを100％まで充電後の、 本バッテリーの残量表示は 55％（45％消費） でした。 本体裏側に、出力は 16,000ｍAh と書いてあるので、 16,000ｍAh × 45％消費 ＝7,200ｍAh が、 ノートPCに給電されたことになるかと。 上記で 33,025ｍW だったので、 33,025ｍWh ÷ 3.7V ＝ 8,926ｍA となるので、 ちょっと数値の違いが大きいですが・・・、 何でかな？よく分かりませんが・・・スルーで（笑）。 まぁ〜私の知識、理解が不足しているということでスルーで（笑）。 ☆3台同時充電に関して☆ C１＋C2+USB-A の３個同時で、スマホを３台充電してみましたが、 特に問題なく充電できました。 本来なら、3台同時充電時の充電状況を 同じ様にUSBテスターで測定して写真撮影して・・・なんですが、 流石に私も、チョットばかし疲れちゃいましたので（笑）、 心残りですが、スルーで（笑）。 一番出力が大きい C1 でノートPC充電時の データを取ったので、ご勘弁下さい（笑）。 ３年保証を謳う良いメーカーだと思います。 （バッテリー残量もデジタルで確認できるし） 確かに本体の厚みは有りますが、サイズとしてはは小さく、 ３端子なので、良いと思います。 但し、チョットばかりお値段が・・・ですけどね。 ※写真添付していますが、充電容量は 25,000ｍA ですが、 給電は写真添付していますが 16,000ｍA との事なので、 割合として 64％ という事になります。 昔のPDではない時ですと、割合は、確か・・・品質が良いモノだと 80％ ？？ で、 イマイチな物だと 70％ とかだったんじゃないかな？？ 曖昧な記憶で申し訳有りませんが・・・。 なので、この商品のように、PDとかQCとかに対応している場合は、 変換ロス等が多くなるから？？？その分、取り出せる割合が、 低くなるのかなって、何となく勝手に考えました。 ポシェット付きなのが、何気に高評価です＾＾。

縦横の大きさでいえばiPhoneの3/4ほどで、角は丸くて持ちやすいです。 その分厚く、厚みは3.5センチほどなのでiPhone3台分くらいあります。 ポートは3つあり、1つがIN/OUT共有です。 65Wでの充電は確認しました。 3つのデバイスを同時に充電しました。 モバイルバッテリー 100％ → 43％ ①iPhone13ProMax（4352mAh） 48% → 98%（＋50%） ②Galaxy S10（3300mAh） 40% → 100%（＋60%） ③タブレット FireHD10（6500mAh） 25% → 100%（＋75%） 計算すると9030mAhくらいです。 3つ同時充電で少し効率が落ちたかとは思いますが、20,000mAh以上あり、十分な容量です。 充電も65Wで早かったです。
