**** BEGIN LOGGING AT Mon Aug 26 03:03:02 2019 Aug 26 15:25:42 hmm, my n900 charger outputs 5.4V Aug 26 15:25:46 not good Aug 26 15:27:25 original? Aug 26 15:27:32 YUP Aug 26 15:27:52 few months ago it was ~5.05-5.10V Aug 26 15:27:55 even with a load? Aug 26 15:28:07 with load it drops to 5.3V Aug 26 15:28:48 which is out of spec. and some time ago i lost a ssd drive due to some other usb device outputting 5.35V Aug 26 16:42:56 my 10 year old charger is 5.02 dropping to 4.99 with an N900 on it. Aug 26 16:43:17 mine was fine too, when i last checked it Aug 26 16:43:22 which was few months ago Aug 26 16:45:58 some smoothing component my have failed taking it over spec? I had a cheap usb car charger that outputted 5.45 I didn't know about it until I tested it recently. I would only use it in an emergency when the device was nearly empty but still not ideal. Aug 26 16:46:33 that's probable, anyway, anything over 5.25V WILL fry devices over time Aug 26 16:51:38 If certain the tester is true then I suppose it's time for a new charger. Aug 26 16:52:04 yes, checked on 2 other usb sources (thinkpad port and opipc port) Aug 26 16:52:18 both ~5.0-5.1V Aug 26 16:53:23 Maybe a 10m uUSB extension lead would have enough voltage drop :P Aug 26 16:53:28 good thing i've found out it's breaking down Aug 26 16:53:36 nah, probably it will get worse over time Aug 26 16:54:01 i will keep the charger for unimportant uses Aug 26 16:54:49 so, lesson for today, measure your chargers/psus from time to time folks! Aug 26 16:54:55 I have only recently got a USB tester and for the price they are well worth keeping in your toolbox. I have found several bad devices. Aug 26 16:55:07 yup Aug 26 16:55:16 i bought me 2 over time Aug 26 16:55:30 the latest is the blueish with white display Aug 26 16:55:44 pretty nifty, shows all the info at once Aug 26 16:56:30 The one I have measures mAh. so if you reset it you can measure capacity too. Aug 26 16:56:38 yup Aug 26 16:58:22 https://www.aliexpress.com/item/32455167954.html?spm=a2g0s.9042311.0.0.1ec64c4dGGVxCT Aug 26 16:58:24 this one Aug 26 16:59:01 there are newer models already, but this one goes dirt cheap and is nice Aug 26 16:59:16 and can go up to 3A Aug 26 17:01:38 this is 7seg but i believe goes upto 27vdc Aug 26 17:02:46 and it seems some sale event is on aliexpress Aug 26 17:03:04 so, grab your usb meters now folks Aug 26 17:04:28 https://www.banggood.com/Digital-Display-USB-Multifunction-Tester-3V-30V-Mini-Current-Voltage-Charger-Capacity-Tester-p-1079409.html?cur_warehouse=CN Aug 26 17:09:10 having uUSB in aswell as A is useful Aug 26 17:09:47 for testing uUSB cables, yes Aug 26 17:09:48 :) Aug 26 17:10:12 unless you have some otg port that can be put in host mode **** ENDING LOGGING AT Tue Aug 27 02:59:57 2019
