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 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.
