Power Walker DC Secure Adaptor 12 V 12VDC 12 W Li-ion Power Supply Mini USV Barrel Connector 5.5 mm/2.5 mm

Just run a discharge test on my new SecureAdapter, with a TP-LINK TD-W8968 which has a 1A rating (but wasn't doing much). The battery lasted 3 hours (maybe a couple of minutes longer) vs the 150 minutes quoted for a 1A load, so that's a good start.A bit worrying to read the other review (2017-02-04) about thermal cutoff at 2A, I also have a higher load router I will try in due course (Billion 8800NL), but as long as it does what I need I will be happy.I would have liked the unit better if they used the LEDs more intelligently, there is a slow green flash when the battery is being used and a slower green flash when it is charging (ie not a great difference in visuals).. The red light is used for errors only with no way to see how much charge is left (by perhaps mixing increasing red flashes with the green as the battery goes flat).And a UK-mains plug version would be nice too, instead a useful adapter to buy is either  Black 5 A Fused Euro Converter Plug 2 Pole Euro Plug to 3 Pin UK Plug  or  BATTERY CHARGER ADAPTOR, 3A BLACK BCA-BK-3A By POWERCONNECTIONS , I ended up with one of both, they are the same as far as I can see, they are built for the 2.5Amp "Europlug" "flat" version of a European 2pin plug and have a set-screw to lock the adapter onto the 2-pin plug.Somewhat oddly I see the price shown is now £60.00 (free P&P) and that the seller (Stuff-UK) I bought mine from for £32 inc P&P is no longer listed. That seems a lot for this device, and it is surprising that there don't seem to be any alternative devices in this 12V UPS area.Edit: Stuff-UK is now showing up again at £28+delivery I see, slightly more than what I paid, but not that much different.2021-11-07 Update - broken:My unit packed-up a few months ago. The battery seems fine (remove screw hidden under the "date made" label). My unit is five years old, has been in use for four. A bit disappointing, and not obvious how to dismantle it just in case there is a loose connection or something similar. But as no one else seems to make anything quite like this I guess I'll have to buy another. At least the price has dropped to £24.xx from 26.xx now.I never tested it on a higher load as intended.

The most important part is that the adapter can handle 25W/2.1A when mains powered but on battery it can shut off as fast as in 2 minutes under that max load (thermal cutoff). It's real maximum sustained output at any condition is 12W/1A. That is seriously misleading and normally I would not recommend it but it gets high points because it has a easily replaceable 18650 li-ion cell, the charging system is well made and ensures a long life for the battery which makes it the best of its kind at this size and price point. Our tests with a variable DC load, various li-ion cells (including simulated) and temperature measurements did not expose any safety concerns.

These plugs are great, I now have 3.Although this listing is by a ‘UK’ seller it is the European plug version - beware!

Funktioniert bei uns seit ca. 8 Monaten einwandfrei mit der Fritz!Box 7590. Kurzzeitige Stromausfälle können damit gut überbrückt werden.

Bra inför vintern om kylan slår till och elen stängs av, kan man kolla på Netflix i 90 minuter på plattan.. eller annat nyttigt :)

Un buon prodotto di livello consumer. Abbastanza compatto, materiali durevoli. Viene fornito con una batteria modello 18650 installata, che è facilmente sostituibile quando inevitabilmente verrà meno la capacità di ricarica/scarica. Questo mini UPS può alimentare con tranquillità la maggior parte di router e modem presenti sul mercato, basta controllare che il proprio dispositivo richieda una tensione elettrica di 12V. Io l'ho collegato al mio FritzBox 7530 e ho constatato che in assenza di corrente mi mantiene acceso il dispositivo per circa 1h e 15minuti.Forse per alcuni non sarà un tempo soddisfacente, ma a mio avviso è un tempo ragionevole se si considera che la maggior parte dei blackout si risolvono nel giro di poco tempo. Poi è chiaro che se si vuol sopperire ad una mancanza di elettricità di 3/4 o 5 ore allora bisogna puntare ad un prodotto diverso da questo spendendo molto di più.

Es una fuente de alimentación para modes/router o similar con una batería por si se va la luz. Yo lo uso para el router de Movistar (tras comprobar que el voltaje, amperaje y diámetro de la clavija era el mismo) y encaja perfecto. Así sigue funcionando la línea de teléfono aunque no haya luz (si tienes un teléfono "alámbrico" de los que no necesitan enchufe). Yo lo quería para que el sistema de domótica de la casa (que tiene su propia batería) pudiese avisarme si se va la luz mediante una llamada al movil. Necesitaba además algo muy compacto por donde está el router. He quitado el transformador del router y puesto este en su lugar y va perfecto.Tiene un botón de encendido y apagado y la batería es de fácil acceso bajo una tapa con un tornillito y se cambia sin herramientas (no está soldada, es como una pila), y es fácil de encontrar repuestos.El aparato es de fabricación alemana, que me ofrece más confianza que otras soluciones similares chinas, y la batería es Samsung.Por poner una pega el cable es algo más corto que el del router, mide unos 90 cm.

Fungerar som förväntat.
