### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Useful unit, could have lasted longer
  

*by M***N on Reviewed in the United Kingdom on 6 March 2017*

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

     or

    , 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.

    Underperforming but well made.
  

*by A***R on Reviewed in the United Kingdom on 4 February 2017*

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.

    Shucko Plug

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