Bin absolut begeistert. Habe jetzt insgesamt 5 Stück gekauft, einfach klasse. Man muss nix umbauen, einfach Akkupack rein und los gehts. Kein lästiges Batterie wechseln mehr.
Tipp: Kauft euch zusätzlich noch 15 – 20 cm usb Verlängerungskabel, so hab ich es auch gemacht. Das Verlängerungskabel kann dann im Zug verbleiben und auf der Bahn sind USB Dosen verteilt zum Aufladen (Lego Bahn mit MattzoBricks in Verbindung mit Trixbrix Motoren & Ampeln).
Habe jetzt gefühlt 3 Jahre gewartet das ich es kaufen konnte (Danke Corona), aber jeden Cent wert.
Absolut Super Produkt,liebes Keybrick Team, das habt ihr echt super gemacht !!!
I am absolutely thrilled and happy with the Keybrick. I regret that I didn’t buy more, but I couldn’t at the time. Please keep me informed when the next batch is coming so I can buy again!
Hallo Team Bewertung sehr gut Wir,Fa. Ochs Elektro haben in unserer ( privaten ) Lego-Eisenbahnanlage bereits 3 Keybrick-Akkusin Betrieb und bin begeistert.Wir haben unsere Lokomotiven mit 2 Motoren ausgestattet und haben keine Probleme.Vor allen Dingen ist das nachladen des Akkus problemlos,da wir ein Ladekabel in der Lok deponieren. Wir möchten weitere 3 Einheiten kaufen;ist es möglich,diese vorzubestellen ?? Bewertung: sehr gut
Superb product! Build quality is exceptional, as well as battery life and features. Personally I see the strongest point in the “Eco” mode as it further prolongs the battery life and is an excellent option for long play at slow to moderate speeds (e.g. as my son prefers it 🙂 ). USB charging connection on the side is also a big plus as the battery no longer needs to be removed from its casing. I’m looking forward to any new product from this Team!
Great replacement for the battery holder! A must-have for all who do not want to throw batteries after batteries away just for running some LEGO trains. Even no screwdriver needed to recharge your train!
Italiano:Prodotto ottimo unica cosa avrei preferito la usb c e la porta di ricarica dall’altro lato o sul lato perché dove messa di default mi ha costretto a riprogettare la posizione della batteria, fili e una parte del tetto del mio treno. English:Excellent product, the only thing I would have preferred was the USB C and the charging port on the other side or on the side because where it was put by default it forced me to redesign the position of the battery, wires and part of the roof of my train.
Grundsätzlich ist der Keybrick ein Hammer Produkt. ich habe 2 Lok einmal mit Keybrick und einmal Powered Up ausprobiert. Das einzige was mich stört, er geht zu schnell ins Notprogramm gegensatz dem Powered Up. Ansonsten ist er viel besser als der Powered Up. Für mich ist aber klar, das ich weiter hin mit Keybrick fahre
I loved the idea of the product from the start but was a bit hesitant because of the price at first. I decided to just try it out and see where it would lead me. The Keybrick One was delivered very fast an came in a very nice box. Instruction on the use are very clear so I could start testing after initial charging.
I have tested the Keybrick One during in my Legoworld 2024 layout and it worked very well and held up quite long. Charging it again was a breeze.
The only “criticism” I have may be the placing of the USB charging point. For me it would work better if it was opposite to the PU-port placement of to the side of the device. This way I am more flexible when recharging it and it doesn’t have to be disconnected at the PU-ports.
But overall I highly recommend the device because it gives you the flexibility of a rechargeable battery with the PU system. Although the price seems hi the quality is so as well.
My three-year old grandson insists on running the Lego trains whenever he visits, so this product was a godsend on saving on batteries and on the ease of recharge. I especially like the ability to choose from different power levels. Only regret is that I didn’t originally order two. I’m correcting that today as I submit another order.
