Dual USB Output Super Slim Power Bank Ultra Thin, 3000mAh Portable Charger Mini External Phone Battery Pack Small Dual Outlet, Emergency Phone Power Backup (Black)

"The party enters the bustling artificer’s shop, eyes instantly drawn to a slim artifact resting upon a velvet cushion. Behold—the Attom Tech PocketRune, a portable mana battery boasting precisely 3000mAh of compact, rechargeable power." Listen closely, adventurers: If you're embarking on smaller quests—like powering up a WLED spell-scroll or lighting your enchanted cosplay armor—this slender power source fits the bill perfectly. The 5V/2A output is steady and reliable. It won't summon lightning storms, but it'll surely keep your devices charged in a pinch. Its greatest charm lies in its sheer portability—this magical rune literally matches the dimensions of your guild-issued credit token (other than thickness, naturally). Surprisingly feather-light, it slips discreetly into your pocket or costume pouch. It feels solid and durable despite the weight—or perhaps because of it. No need to summon your 3D printer golem today, friends; this battery is ready to adventure straight out of the box. A simple side-mounted button reveals four pleasantly bright LEDs to indicate remaining power. These glowing indicators generously grant you six clear seconds to assess the situation—ample time even in the midst of battle or cosplay chaos. Considering that standard LiPo packs cost roughly 10-15 gold pieces (err, dollars), the pricing on this PocketRune is right on target. It strikes a satisfying balance between cost, capacity, and convenience. Artifact Summary: Capacity 3000mAh—modest but great for quick adventures Size & Weight Amazingly compact; literally credit-card sized Build Quality Lightweight yet reassuringly solid Power Output Steady 5V/2A—Reliable for most small devices Indicator Lights 4 bright LEDs, visible for 6 clear seconds Pricing Competitively priced compared to plain LiPo packs Pros: * Ultra-portable and perfectly sized for costumes or small electronics. * Solid build quality; no 3D-printing side-quests needed. * Bright, clear power indicators for quick checks.

It's a compact battery for special use cases, don't expect it to run your laptop or iPad for hours. However, it is lightweight, and has proven quite durable. I use it to keep a pocket bluetooth receiver from running out of power overnight. It has also come in handy as the "extra" extra tiny 5V usb hub power supply that apple insists is nesessary to read a USB-A flash drive with their old lightning connector. This is not a "fast charge" or "smart charge" device that I am aware. It is the older generation of tech, but done well. You may want to make note of the 3 ports on the battery. There is USB-A, USB-C, and that weird "micro-USB" port on it. I just used the "Micro USB" for charging with a magnetic USB cable (sold separately). I think there is an updated version from same manufacturer. Might be worth reading the specs on those charging ports, depending on.what you want to use it for. 📟

I took this along with me on a 7 month trip that spanned 4 continents and 19 countries. It worked. It survived the trip. My biggest gripe is that the draw when charging the battery is so low that many/most USB chargers don't recognize that it's even there. So if you want to plug it in overnight, it might not charge. This is entirely due to the usb chargers having power-saving features (a good thing!) and not necessarily a flaw in the battery.... but it is a hassle. Similarly, it charges painfully slowly. The capacity is about 35% of my phone battery but it takes about the same amount of time to charge as my phone does. Capacity itself is as-advertised: very few mAH. It was enough, though, to keep my cellphone functional enough to navigate somewhere after an all-night bus ride depleted my battery. It was enough to recharge a headlamp enough to see a dark path. It was enough to top-off some earbuds. And the best part is that you can actually charge 2 devices at once while also charging the battery (assuming you have enough usb cables). That was really handy. So if you really just want a back-up/emergency battery pack that can add about 30% to your phone's capacity: this is a lightweight/compact solution that works well.

The size is great but this little powerbank doesn't have enough power to charge my Samsung phone after the first light (25%) is used. It just fails.

Got this power bank to power a small travel router. It’s small and does what i need.

I had two of these and they were great for what they are. Small, light little booster to toss in your pocket when you're headed out the door on a half batt.. Add a 3 inch charging cable and you can always get that uber home...

I can see how this might work for a LED display for anime CON or larping, but for backpacking it only charged my pixel 9 40%. I figured I'd give it a try for the price. It also doesn't charge via USB C for me, despite comments saying it does. Only charges via USB micro. Also previous comments saying it loses charge quickly while sitting around means I can't rely on it for backpacking.

Relatively expensive but compact. The USB A port broke off early but the other port options have worked.
