KeymasterIs there a name for this one?

I have a bigboy bank on the slow boat that (hopefully) does just this minus the ruggerized part;[IMG]
Took a bit of a gamble ordering this one since reviews on this exact model are near impossible to find but i do have some experience with the brand and those are decent enough to warrant this shot in the dark.This model takes 1-5 18650s behind an easily accessible battery flap so you can fill it up with 5 and if you ever need a cell for your flashlight you can just pull one out and the bank will still work fine (tho with less capacity). Reason i ordered this specific model is because of the multi-voltage 18W input jack that should charge the cells at a usable speed, and because it has a qc3.0 output port next to a regular one that i am hoping will still output 2amps. It will still be able to charge the cells inside from a regular USB power-source in a pinch but that will take too bloody long for me once i fit this with high capacity cells (5v at 1A and you’re looking at minimal 12hr charge).
If it works the way i hope then it will be a keeper, let me know if youd like to see a little review once it arrives.

KeymasterNot really, the ad was also being quite vague about the model so its difficult to find this exact one. Its elder sister without the QC functionality and a dc multi-voltage output instead of an input is easier to find but a completely different beast altogether. Thats the Quidian 185 TY to get you going, what model number the one i have ordered is exactly i could not tell you. I found it through multiple auto-translation steps and a lot of link hopping. The brand is being marketed a Qidian, Tese or more correctly 七电. Ill post the exact model here once i receive it (if there even is a latin/alphanumeric model number on there).

KeymasterI think I found it, though it maybe sold out, and if it is the same, there is no mention of QC so it may not be the same. I look forward to your review.
I like easy access batteries and battery banks. Like you said “it let’s you carry spares” in a usable container.

KeymasterLove this option; probably lots of reviews around. Might give my Nitecore F1 a run for its money (I love the ultralight compactness though).

KeymasterI Love the F1 as well. It works really well for charging slow. But for things like an iPad, the battery is not enough. Unless you have very good batteries. What I find it really good for is to use in combination with a solar panel. You can charge the battery, but if there’s not enough power from Solar, he steals from the battery some, and still charges the device. Without Solar, the F1 can’t charge an iPad much.
This is where some of the larger battery banks that can do pass-through charging shine.

KeymasterWell the one without the qc and multivoltage input is actually quite common and easy to find but people really only get that one to charge oddball devices or use it as an improved bench power supply. If that’s what you are looking for than its a pretty solid bank but i really want something that charges quicker.

KeymasterI use the Streamlight EPU-5200 for my EDC power bank. It’s IPX-4, sealed against the elements pretty well (lots of sand where I live), and has four lights that let you know how full it is (5200 full). Bare bones, but I love it.

KeymasterI recently bought an Antigravity Micro-Start XP-1 for dual use. I keep it in my vehicle for emergency jump-starts and for charging anything that needs charging. It’s a 12,000 mAh battery with output jacks for the short jumper cables, a USB jack, and a 19V DC jack for laptop charging. I knew going in that it would not have a tip to fit my HP Spectre X-360 so I bought a charger tip package from eBay which looks like it has tips to charge everything except maybe Dilithium crystals or Phasers. I’ve used it twice now for jump starts. It will remain in my vehicle. I have smaller emergency chargers for the phones. I’m not thrilled with the softcase that came with the XP-1 so I’m going to put it, the tips, and a few other items into either a MaxP Beefy or a Vanquest Huge – won’t know which ’til the huge arrives next week.

KeymasterWhen I ordered the Onite charging tip set I hoped that the common plug on the bottom of all of the tips would match up with the cable supplied with the XP-1 charger. It did. That gives you a lot of possibilities and makes it an extremely versatile combination of products. The last accessory I’ll probably acquire for this setup is the Cigarette Lighter 12V receptacle which plugs into the 12V output on the XP-1.

KeymasterIPX6 or 8 would’ve been great, but hey we take what we can. Is there anything on the market that has swappable 18650s (and can run on 1) out there, and highly water-proof/resistant?
Anyone?
Thanks!
September 29, 2025 at 11:44 am #27942admin
KeymasterWell, there probably are powerbanks like that but waterproof in combination with an easy accessible battery compartment makes for a more difficult design than usual. Combine that design difficulty with the double niche you are looking at (waterproof nor user replaceable 18650 are main stream) and it might be difficult to locate and probably expensive. That blitzwolf lantern and some good ol powerbank integrated flashlights spring to mind but off the top of my head i cant point you towards what you are looking for exactly. Will keep an eye open tho.

KeymasterA two-way (input/output) flashlight/charger sounds like a really good opportunity. With IPX6+ of course. 🙂

KeymasterFenix cl30r. Bulky for your purpose but waterproof, 3×18650, usb in and out.

KeymasterWell this puppy arrived today, will be putting it through its paces in the next couple of days.
For those interested the model number is qd185-fc and going by the packaging and manual is fully intended for the Chinese market only.

KeymasterWell good luck with that then! Let us know how it works out for you.
L’chaim!
