Do you carry around a Continuity Tester?
I carry one around all the time, you'd be amazed at how many Live/Neutral have loose connections or missing a ground when you plug in the cord.
I don't, but I probably should. Got an old nightlight I've been meaning to toss in my bag but the tester is the better way to go. Will have to try to remember to pick one up the next time I'm in crappy tire or sprawlmart.

I carry one of those contactless voltage testers with me mounted on my ebike.
jut to check if outlet is live.

That is a great idea as well.

those thick inner tubes are worth of trying.
I havent had any punctures/flat tires on my summer ebike for at least 2 summers.
they are heavy and bulky so no good to carry with you.
At least 4 times heaver and they take 4 times more room than regular tubes , you cannot fold them really , so thick.

Starbucks inside a Safeway?

(No pic, but I used the same outlet I posted earlier twice yesterday. Took my kid down to Stanley Park in Vancouver and rode around the seawall. A near 100km day on the bike, all in.)

It is the COOP on 10th and 10th downtown.
It is a sitting area, next to a mercury sushi place which is apart of COOP. They spoke some asian language to each other as they were preparing the mercury for consumption.

Starbucks is usually Safeway, which is

and

That particular Safeway had a Starbucks as you enter. Interestingly Safeway implemented a loss prevention tactic of blocking off the entry/exit with water bottles. The only thing good about Starbucks is you can get a free cup of ice and/or water, plus they dont care if you dont buy anything or dont buy anything PLUS use their shitters.

Here is me charging my e-bike at a workplace parking garage:

I had a small 180W charger with me and had a power meter placed in line to verify charging.

There was a plugin-hybrid Toyata Prius also sharing the same outlet with me. Nobody's going to notice my little ol' me pulling 180W compared to the Prius probably pulling near maximum 1500W for a 120VAC outlet.

Anybody could pull in with an e-bike and charge here as long as you don't look like a bum and catch the attention of the infrequent security guards. There are workers from many companies using this parking garage in a commercial district. Nobody knows anybody.

so if I feel like getting a coffee and juicing up, don't go to Tim Hortons where the cops hang out, go to starbucks where the cops aren't welcome and I don't have to buy something to use the shitter

I'd rather push the bike home than stop at Tim Horton's. Especially if I want a coffee.

im not a Timmies person either, it tastes funny and people wait in loooong line ups to get some. I figured they were putting something in it. i don't like starbucks. Van Houtte coffee at Chevron and chevrons typically have an outside plug

Its alright to sit there while your juicing up. The majority of the employee's at Timmies are asian descent with some sort of accent, while Starbucks can be anything usually caucasion or asian but always fluent english. I never had a problem not buying anything. Problem is Timmies has outlets at the back door, McDonalds too, most chain restaurants. Few have outlets in sight, I got one spot a mexican place. The subway had a rotating mall sign that was good but someone turned off the outlet.
The fish sanctuary downtown calgary had outlets but now they put plastic covers over with a lock.
I'm not sure if someone saw me juicing up and decided to turn them off, or lock them up. Fish sanctuary was maybe twice, maybe. But subway sign was a lot.

I signed up for a Chargepoint account and have a j1772 connector which should be delivered Tuesday. Huge number of level 2 charging stations in the lower mainland, the majority of which are gratis to use. My charger works on both 120 and 240v, but it has the potential to put out 700 watts more on 240. Will hopefully mean a goodbye to range anxiety and hunting for random outlets. I look forward to doing some extended exploring this spring and summer.

Evseadapters.com out of California. I went with the j1772 to c13 version. Probably could have built it cheaper myself but the cost isn't terribly unreasonable for the privilege of just plugging it in.

Something is up with my battery. I should be getting atleast double the range for 36Vx27Ah=927Wh/25Wh/km= 39km but I get half.
Perhaps the cold weather damaged it.
Perhaps the 8A charge rate is too much for 18Vx27Ah half pack.
Controller is 36V 35A
Batteries are Ryobi 9+6+6+6Ah times two (put in series) to mack complete pack.
The first rendition was 6+6 then I snagged some 9's from HD in E-town and grabbed another 2 pack of 6 to get it where its now.

Next pack is going to be Samsung 25R's but 15S because I use laptop chargers good for 5S.

when I was working around prince George my Ryobi plus one batteries were fully charged at home, put them in the back of the truck, drove an hour went to use the drill and it was dead, all 3 batteries were dead and it was minus 10 Celsius. I had a Ryobi NiCad pack and it worked. cant use the Ryobi in the cold, I still use those plus one batteries but only in warm temperatures. my Milwaukee grease gun 18v only pumps one tube of grease right now instead of 1.5 to 2 tubes of grease per battery.

heres a Ryobi battery guy , video starts at 4 minutes and 7 minutes, I was thinking, dude, duuuude don't do that!

in that video it looked like Samsung 20q 2000 mah but you have a 9ah battery, sounds like a 3000mah not a 2000mah cell.
also sounds like youre using basically 2- 5s9p batteries at 35amps max or 4 amp max per cell. id almost split your batteries into 15ah and 12 ah and run them separately so they can generate their own heat so you can keep your ah capacity.

if you have 20q cells in your batteries heres a link to the data sheet. look at section 7.6 and 7.7 and that could explain your range loss

http://gamma.spb.ru/media/pdf/liion-lip ... 50_20Q.pdf

I did a test on a battery packs ability to maintain its temperature in cold temperatures with low amp draw and the battery cant maintain its temperature and you lose capacity/range. im running my packs at a higher C rate right now, it was snowing here yesterday morning and im running 4p of 25r at 35amps at speeds of 30 to 60km/h for a 25km round trip for work and my battery stays warm, at 1c battery temperature drops right down to outside temperature, wh/km goes up and it sucks
