J2621 Power Bank Portable Charger 20000mAh 45W, PD3.0 QC 4.0 Fast Charging Battery Pack with LED Display,2 USB-C,2 USB-A for iPhone 15 16, MacBook

Product is excellent quality and holds a charge for a longer time than my portable power banks from walmart. Color is accurate to product images and it features two USB slots and 2 USB-C slots, it also comes with one usb-c to usb-c cord bit i recommend buying another cord separate due to the short length. I use this power bank to add extra play time on my ROG ally and it works excellent.

I only used it once and it was pretty good. Charged my phone a couple of times and my watch. Charged 3 things at once. It also can charge while it’s charging.

It’s a little heavy! Not something you’d carry around in a little purse but it’s working unbelievable great! It’s charging my iPad, iPhone 16Promax my laptop top my AirPods all in one charge and I have not charged my power bank as yet! This is just what you need especially in cases of power outages! Must buy! Package was delivered really fast!

Durable and works well so far. Easy to use. Feels pretty solid. Took a little time to charge up charger itself, under 45 min. Portable. So far I would recommend and purchase again.

This is a good charger with both dual in and out ports. It shows the percentage of remaining charge in numerals on the side (they light up). My only complaint is that this brick is heavy. I keep this one in my office, since I don't have a charger for my phone that reaches my desk. For portable power banks, I use smaller, lighter versions that don't weight down my bag.

I bought two of these - one for my husband and one for me. I found that we really only needed one! This charged my phone from 6% to about 60%, my husband’s from 15% to 80%, then mine again (still charging but currently up to 73%) and there’s still 42% battery life on the charger. I haven’t even taken the other one out of my bag. And this was cheaper than my anker one that attaches to the back of my phone and charges much better. It does require that you plug it in with the cord but you can just leave it in your bag while it charges. Highly recommend!

This little power pack is an amazing piece of technology. I can charge my picky Lenovo laptop with it as long as I have a cable that will deliver the wattage. It's almost half the size of every remote charger I was using til I bought this one, and it lasts almost as long as the big ones. I would call it an absolute must for travelers. I note it is significantly less expensive than rival devices with the same specs.

I needed a TSA approved Power Bank for a recent 9-Day European vacation with my wife. The Juovi J2621 20000mAH / 45W capacity really delivered. Providing the capability of charging up me and my wife's smartphones on the flights and European trains when we really needed it. And recharging the power bank with our Voltage Converter in the 4 hotels we stayed in was completely effortless. During a small group guided tour of the Vatican Museum & Sistine Chapel, I neglected to bring this powerbank along and almost ran out of power on my smartphone after taking several photos. We ended up with the help of a local going to a local Roman electronics store and purchased an additional 10000 mAH charger just to get through the rest of the day. If I had the Juovi J2621, that wouldn't have to happen. Great product, highly recommended.

As described. Pretty impressed so far. Versatile: charges all my devices and accessories, as well as powering usd lights and a used fish tank aerator. A fully charged power bank: charged a Samsung tablet 60% in 1.5 hours and used 34% of its charge charged my Pixel 8pro 80% in 1.5 hours using 30% of its charge charged a small Lenovo tablet 21% in 45 minutes using 8% charged a Thinkpad laptop 50% in half an hour using 48% The noted uses collectively depleted 100% of the power bank. Devices noted "rapid charging". It took 8.5 hours to fully charge it. Recommended.

hij doet het goed ik heb er schik van

Solid and well built power bank. Can supply a wide variety of voltages from its 2 usb-C ports, from 5.1 to 20V. Capacity I measured was 70.25Wh, discharging from 100 to 0% at 5.1V, 1.6A. That is a bit less than the rated 75Wh. To recharge at 20V from 0 to 100% took 2h 22m and 87Wh (about 4.2A). It has a trickle mode for charging low-power devices like earbuds. It has an LED telling you how much % is left. Weighs 378g.

Die JUOVI Powerbank mit 20.000 mAh Kapazität präsentiert sich als leistungsstarker Begleiter für unterwegs und richtet sich vor allem an Nutzer, die mehrere Geräte gleichzeitig laden möchten. Design & Verarbeitung Optisch fällt die Powerbank durch ihre grüne Farbgebung angenehm auf und hebt sich von den üblichen schwarzen Standardmodellen ab. Das Gehäuse wirkt stabil und ordentlich verarbeitet, wodurch sie auch bei häufiger Nutzung einen robusten Eindruck macht. Trotz der hohen Kapazität bleibt sie noch transportabel, ist jedoch erwartungsgemäß etwas schwerer als kleinere Modelle. Leistung & Ladegeschwindigkeit Mit einer maximalen Leistung von 45W bietet die Powerbank schnelles Laden für eine Vielzahl von Geräten – darunter Smartphones, Tablets und sogar einige Laptops. Besonders positiv ist die Unterstützung von Schnellladefunktionen, wodurch kompatible Geräte in deutlich kürzerer Zeit aufgeladen werden. Die Kapazität von 20.000 mAh reicht problemlos für mehrere Smartphone-Ladungen oder zumindest eine vollständige Laptop-Ladung (je nach Modell). Anschlüsse & Flexibilität Die Ausstattung mit 2 USB-C- und 2 USB-A-Ports ist ein klarer Pluspunkt. Dadurch lassen sich mehrere Geräte gleichzeitig laden, was sie ideal für Reisen oder den Alltag macht. Die USB-C-Anschlüsse ermöglichen zudem sowohl schnelles Ein- als auch Ausgangsladen. LED-Anzeige Die integrierte LED-Anzeige ist praktisch und zeigt den Akkustand zuverlässig an. Das hilft, den Ladezustand besser einzuschätzen als bei einfachen LED-Punktanzeigen. Alltagstauglichkeit Im täglichen Gebrauch überzeugt die Powerbank durch ihre Vielseitigkeit. Egal ob unterwegs, im Büro oder auf Reisen – sie bietet genügend Energie, um nicht ständig auf Steckdosen angewiesen zu sein. Nachteile Relativ hohes Gewicht aufgrund der großen Kapazität Kein kabelloses Laden (falls gewünscht) Design zwar auffällig, aber Geschmackssache Fazit Die JUOVI Powerbank ist eine leistungsstarke und vielseitige Lösung für alle, die viel unterwegs sind oder mehrere Geräte gleichzeitig laden möchten. Besonders die Kombination aus hoher Kapazität, 45W Schnellladung und mehreren Anschlüssen macht sie zu einem sehr guten Allrounder.

Value for money. Sturdy, comfortable in hand despite being a little on the heavy side . Rapid charging, 50% in 35 mins (iPhone 15 pro max). Charges pretty quick too. 50% charge used 15% of the units power. Highly recommend
