4Smarts Rugged TitanPack - solar panel gimmick

Feedback on 4Smarts Rugged TitanPack UltiMag – solar panel performance

I have used TitanPack UltiMag power bank intensively over a two-week period. It was used to charge two smartphones (each with a 5000 mAh battery), with only one access to 230V power during that time.

The power bank was placed in direct sunlight every day from morning to evening, but the solar panel failed to charge the device to a usable level. After four days, the battery not even went from 25% to 50%. In practice, the solar panel is a gimmick and not a viable solution for charging in remote areas.

That said, the rest of the product is outstanding:
* Rugged and reliable build quality
* High capacity (20,000 mAh)
* Multiple USB ports for flexible charging
* Thoughtful design, although a bit heavy — understandable given the battery size

Conclusion: A great power bank for demanding conditions, but the solar panel should not be a deciding factor. It does not deliver meaningful charging performance and may mislead users expecting off-grid wilderness and emergency functionality.

Feedback zur 4Smarts Rugged TitanPack UltiMag – Leistung des Solarpanels

Ich habe die TitanPack UltiMag Powerbank über einen Zeitraum von zwei Wochen intensiv genutzt. Sie wurde verwendet, um zwei Smartphones (jeweils mit einem 5000-mAh-Akku) zu laden, wobei während dieser Zeit nur einmal Zugang zu einer 230V-Stromquelle bestand.

Die Powerbank war jeden Tag von morgens bis abends direkter Sonneneinstrahlung ausgesetzt, doch das Solarpanel konnte das Gerät nicht auf ein brauchbares Ladelevel bringen. Nach vier Tagen stieg der Akkustand nicht einmal von 25 % auf 50 %. In der Praxis ist das Solarpanel eine Spielerei und keine praktikable Lösung für das Laden in abgelegenen Gebieten.

Davon abgesehen ist der Rest des Produkts hervorragend:

* Robuste und zuverlässige Bauqualität
* Hohe Kapazität (20.000 mAh)
* Mehrere USB-Anschlüsse für flexibles Laden
* Durchdachtes Design, wenn auch etwas schwer – verständlich bei der Akkugröße

Fazit: Eine großartige Powerbank für anspruchsvolle Bedingungen, aber das Solarpanel sollte kein entscheidender Faktor sein. Es liefert keine sinnvolle Ladeleistung und könnte Nutzer täuschen, die netzunabhängige Nutzung in der Wildnis oder im Notfall erwarten.

Hi there! 😊

Thank you so much for your detailed feedback – it really helps us improve! 🙌
We’re super happy to hear that you value the rugged build, high capacity and thoughtful design of our TitanPack UltiMag. That’s exactly what we aim for – reliable performance in demanding conditions. 💪

Regarding the solar panel: you’re absolutely right – it’s designed as an emergency feature to provide a little extra energy when needed, but it can’t replace a proper charger. We’ll make sure to communicate this even more clearly in the future. 👍

We’re thrilled that you’re overall satisfied – and hope your TitanPack will continue to be a reliable companion on your adventures. 🌍🔋

Best regards

The powerbank was fickle

The powerbank I received was fickle..was loading and then stopping and continuing. I complained and got a reply after over a week - granted it was holiday time - but then after I sent the powerbank back. Was delivered on Monday and on Thursday still no acknowledgement that the return was received or any reply to my request for a full refund. That's not good service.... sorry to say

Thank you for reaching out and sharing your feedback. We sincerely apologize for the inconvenience you’ve experienced with the power bank and the delays in our response.

Over the past two weeks, our company has undergone a move, which has unfortunately affected some of our internal processes. We understand how frustrating it can be to wait for a resolution, especially during this time.

I’m glad to inform you that your refund has already been processed. We appreciate your understanding and patience during this transition. Your feedback is important to us, and we are committed to improving our service moving forward.

Thank you for your understanding.

Great Product. High quality materials and good performace. Been using it constantly the last few weeks.

For steam deck oled ist one of the best, because of it size. The Capacity is a bit shy , but it is a very small product. Give you 20-25% in AAA games 45watt 10000mAh. The price it is not too expensive and total weight 200g . I even made a video about just to help steamdeckrrs out there.
