How to use multimeter to test v charges? Just test the voltage?

Yup. Test voltage to see approx percentage. But just fyi it is unloaded so if placed with load may be different percentage.

like NiMH nominal is 1.2v then we consider 50%
1.5v can consider topped 100%
1.0v already close to 10%

Ok got it... thanks!

Is this good for home use? Battery if fully charged, what is the discharge rate? Should i take out the battery when not in use or just leave it there?

aside from my neck hurting...
for home use is hard to say since there's no specs that states how many lumens etc each mode is...
so if the low isnt low enough...well prepare to get blinded at night

as for discharge..thats anyones guess since its not something popular...leaving battery in wont matter since its li-ion...unless it discharges in a day

Should be plenty enough for home use. Though I would rather get a Sofirn SP33 for that price. Much better build with proper LED

If you insist on getting that then here are my thoughts.
-Zoomie head also means it is not waterproof so just beware in case you accidentally drop in some water if you decided to take it outdoors.
-Built-in rechargeable may incur risks since you are charging a highly reactive battery in a sealed aluminium bottle. Highly suggest getting an external charger like an XTAR SC1 just for safety reasons
-Aliexpress is a pain to wait. You might need to wait up to a month or two just for a single light. Might as well find something from local say Lazada or Shopee where shipping is faster even when seller is in China

I dont know what's the lumen but would xhp70 has same lumen across all?
Also what's the min lumen for small handheld light flashlight these days? Purpose for maybe walking the dog at night around 45 min...

Looking to buy 2 piece

Thanks

If need to use during rainy days outside is still OK not expecting to go diving with it as it'll be kept at cabinet near the entrance door. SP33v3 is slightly more expensive albeit better known brand over here though.

But also concern with 5000maH battery, how long should I expect it to last per full charge at full brightness?

Also small flashlight, would xhp50.2 or xp-L v6 better? What's the ideal battery size typically ie 1200maH or higher?

My experience buying fro Aliexpress usually 2 weeks max only one occasion didn't arrive at all and being disputed.

Separately can one use the fast mobile charger ie ugreen 36w to charge this built in charger flashlight?

hmm that site actually shows 2 diff lights...1 with xhp70 another with xhp110...
and there is no info on what the lumen steps are...as in whats the lowest / middle / high etc...so if low is like 100 lumens...thats quite alot for home use...
also i feel that listing is a con...cos the max lumens for those are like at least 3000 lumens?
and assuming that guy is using the max lumens for illuminating that SUV there...which at about 10m away...well it doesnt look like a 3000lumen beam...my rm20 mydiy light also looks the same...

anyway walking dog...some variable one from 50-300 lumens max can already...
just to add on...something small like a nitecore tiki works extremely well already for that purpose...and u can always have it on ur keychain...

While it is close to 3400mAh it can't even do any load more than 2 amp. Useless junk. Use for powerbank 4 parallel also keep shutting down.
