I got this since my older battery chargers were on their way out. I saw this one and wanted to try it out, and needless to say after a while of using this battery, its wondeful!This battery has a lot of flexibility — 3 overall ports that all allow charging. The USB C port that allows you to charge the battery also allows you to charge your devices which is a great advantage to other batteries. It does its job wondefully and charges my phone (Android in this case) in a reasonable time compared to my other charging ports. Its very easy to tell when your battery is low and comes with a cute pouch! It fits in your pockets seamlessly. It also has a little built in flashlight, which, I don’t use often but definitely comes into clutch sometimes.I would recommend keeping the battery out of its mesh pocket when charging. It heats up a little when charging but only near the area of charging. As well, the charging cord for the battery is a bit on the shorter side but still can charge on any personal USB C cords.I would recommend this battery for anyone!

I Honestly got nothing bad to say at all about this product. I don’t write many reviews on things but this power bank is just great to have around. I carry it in my bag everywhere I go. It’s super light weight, charges fast, lasts long and the paw print design is awesome for any animal lover out there. I’d definitely give it 5 stars and two paws up.

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.

I got this based on reviews plus my daughter wanted a solid battery charger for her iPhone 14 Pro Max because she doesn’t like the mag chargers. This came partially charged. Love the soft texture feel, not any heavier than a mag charger but larger. It was the exact size of my iPhone 13. The optional multi charge abilities was also a plus. We purchased another quality known brand mag first but couldn’t even get it to charge or turn on. It went back immediately and we got this. My daughter loves the paw battery indicator light. Hopefully it works long term. It had a link you could scan for video, instructions, and other products, and support in addition to the paperwork included. It also came with cable and soft mesh bag to carry it in. So far upon opening and first charge we are very happy with this purchase. Simple, lightweight, easy to use charger what’s not to love?

Have only had this power bank a short time, so I have no idea how long it will last, or how long it will perform well, but, the size is good, I like the orange color that I chose. Its easier to find than black. It charges my phone fast and it does not seem to shut off on low draw when I charge my AfterShokz. I would like for it to recharge faster. Even it is not slow, but it takes awhile on my charger, which is fast. Same one that came with my Samsung galaxy phone. Bottom line is yes, I would recommend it. Maybe some day there will be one half as big and twice the power, but, for now, this seems a good choice. Also, the rubbery feel is good. Does not slide out if the hand easily. The bank has a small light. It works but if not bright, which is okay. The method of turning it on and off seems adequate, but maybe it is too easy to come on, so be aware of that. Not a deal breaker, but it exists. A double click on the button turns it on, a long hold turns it off. I can see me buying another one, even though I have a lot of power banks.

Embarking on a journey to find the perfect portable charging companion led me to the INIU Portable Charger, a promising device boasting a 10000mAh capacity coupled with USB-C in & out technology for high-speed charging. Designed to be the power lifeline for a range of devices from the iPhone 15 to the Samsung S22, its sleek form and robust specs appeared tailor-made for the demands of a modern, mobile lifestyle.However, as the glossy sheen of initial impressions faded, the reality of daily use painted a starkly different picture. The integration of the INIU Portable Charger into my tech routine revealed several significant flaws, starkly contrasting with the high expectations set by its advertised capabilities. This stark discrepancy prompted a thorough reassessment of its effectiveness and utility in my digital ecosystem.Pros: 🌐 Versatile Compatibility: Initially, the charger’s compatibility was its most appealing feature, promising seamless integration with a wide array of devices. This universal compatibility was a beacon of convenience, envisaged to simplify the charging needs of my tech-laden life. Envisioning a world where a single charger could meet all my devices’ energy needs, the INIU Portable Charger seemed like a dream accessory, eliminating the need for multiple chargers and simplifying my tech setup.Cons: Questionable Capacity: Despite its promising 10000mAh capacity, the charger’s actual performance was underwhelming. It consistently struggled to fully recharge my devices, often depleting its stored power after a single use. This glaring discrepancy between advertised and real-world capacity became a source of frustration, leaving me in need of additional charging solutions far sooner than expected. The reliability I sought in a portable charger was compromised, as the INIU Portable Charger failed to deliver the endurance and dependability it promised, making it difficult to trust as a primary power source for important devices.Pros: 💼 Sleek Design: The design of the INIU Portable Charger was undoubtedly its strong suit. Its slim, lightweight profile made it an attractive and practical choice for inclusion in daily carry, promising not to add unnecessary bulk. The aesthetic appeal of the charger, with its modern lines and minimalistic style, was designed to complement the array of devices it was intended to support, suggesting that functionality and form had been considered in equal measure. This thoughtful design was a reminder that portable power could indeed be both effective and elegant, fitting seamlessly into both professional and casual contexts.Cons: 🔄 USB-C Limitations: The inclusion of USB-C technology in the charger was a key selling point, suggesting a step forward in charging efficiency and speed. However, the reality was a letdown. The USB-C port’s performance fell short of current standards, with charging and data transfer speeds lagging behind those of other devices in my tech arsenal. This underperformance was particularly noticeable during critical moments when fast charging was not just preferred but necessary. The slow recharge rate via USB-C, a standard I had come to rely on for its rapid power delivery, meant that the charger was often bypassed in favor of more reliable alternatives, undermining its position as a go-to charging solution.Reflecting on the experience with the INIU Portable Charger, it’s evident that while it promised to be an all-encompassing power solution, the reality was a blend of style over substance. The sleek design and broad device compatibility initially suggested a future where charging concerns were alleviated. Yet, the shortcomings in capacity and the underwhelming USB-C performance highlighted significant gaps between its potential and actual utility. This journey from anticipation to disappointment underscores the critical need for portable chargers to not only meet but exceed the demands of the modern digital landscape.As I continue the search for a truly reliable portable charger, the lessons learned from the INIU Portable Charger experience remain front and center. The quest for a device that seamlessly marries form with function, offering dependable, high-speed charging without compromise, goes on. Here’s to hoping the next charger not only matches but surpasses expectations, keeping our devices—and by extension, our lives—powered and uninterrupted.

What I love the most is this feels like a well made product that has what everyone wants without being too overly engineered or gimmicky.The overall design feels durable enough to use as a daily driver. I also confirmed it could charge two devices at the same time with no issues. It won’t do Fast or Super Fast charging on my Samsung Note 20 Ultra, but I also don’t expect it to at this price range. I also love that the USB-C is both in and outgoing power.For the price point it’s everything I wanted in a power bank.Also the added light isn’t pro grade, but it’s actually pretty good for an added feature. It’s nothing special but plenty of light for those situations where maybe you dropped something or need to read some text.If I had to list a con… I guess the charging cable is small (approx 1ft), but this is plenty imo. If you’re charging a power bank, it’s probably staying near the charger. Maybe it could have come with two cables, but I’d rather use my own longer cables for charging my actual phone. So really I prefer it this way, but someone may not like that the included cable is so short. If that’s you, then go buy a longer cable with this. The Iniu still feels like the best device for the money right now, and I really like it personally.UPDATE: It charged my phone in about 30 minutes from around 30% to 85% (where I cap the charge). For standard charging, that’s exactly what I expect. Easy 5* product with everything else said.

I currently don’t own a portable charger and thought one might be useful if on a long hike, out and about, or on vacation. I did quite a bit of research and saw that Project Farm on YT has reviewed this INUI BI-B41, along with many others, and it was one of the top chargers, also with a good Amazon rating. The brother of this, the BI-B61 came out marginally better but it has above average Amazon returns and the form factor, small but thick, was not as pocketable for my needs. I also didn’t need a vulnerable, built-in phone stand, so, I bought this one..It arrived with about 50-60% charge. I didn’t time how long it took to fast-charge it, but it was at least an hour. Project Farm has all the details for charging power and times. The supplied, short USB -A to USB-C is obviously not a fast-charging cable for my Pixel 6a. I used my own USB-C to USB-C fast-charge cable and the phone did charge at the anticipated fast-charge rate and was equivalent to my 20W charging brick. I usually only charge between 25% and 80% to prolong the battery life, and to get the quickest charge time (as you approach 100% the charge rate in a phone will automatically drop to a crawl as part of the battery management algorithm). I’ve used the charger on my headphones, phone, and earbuds. I will also use it for my mirrorless camera batteries in the future. It does not get hot.So far, it is working as I expect. It is also similar, in terms of size, to a small phone, so it fits nicely in my pockets..I’m not keen on the LED “animal paw” symbol. I’d much rather have a row of 4 or 5 LEDs, or a percentage readout. The paw looks childish. Each of the 4 pads indicates the level of charge in 25% increments, and the level of charge has a flashing pad when charging. The LED is very bright in a dark room but you can always turn it on its back..At $20, this is a very good buy. Hopefully the 3-year warranty, if required, is honored. I will be back to update this review should I have any issues..So far – Highly recommended for your consideration!

I like the slim build. It’s almost the size of my phone. It will charge my phone or iPad up twice before it needs recharging itself. I was hoping I would get more charge out of it than that, but I only use it in case I forgot to charge one of my devices up and have no other means to charge it. It comes with a short cord that is used for recharging it and for charging my android phone, and maybe an android tablet, too, I don’t know as I don’t have one of those. I already had a short usb port iPhone/iPad cord that can be used to charge those devices, otherwise you have to buy one. I am able to charge two devices at the same time. The four stars instead of five is because it doesn’t come with an iPhone/iPad charge cord ( note: this cord has to have one end of it usb port and the other end iPhone/iPad compatible. I bought it on Amazon ) and it doesn’t hold as much charge as my old bulky portable charger that held enough charge to recharge a device 4 times instead of only 2 times. That being said, I didn’t find another device that could either, and I am still happy to have this charger.
