Batmax 4X AAAA Ni-MH Rechargeable Batteries + LED Dual USB Charger with Type C Port for Surface Pen Active Stylus and More

Quick take

This set pairs four 1.2V Ni-MH AAAA rechargeable batteries (450mAh) with a compact LED dual USB charger that uses a Type-C port. It is a convenient choice if you have a device that takes AAAA rechargeable cells, including active stylus setups like Surface Pen models. The main thing to double-check is battery size and charger compatibility, since AAAA is not the same as AA, AAA, or C/A/N cells.

Pros and cons

Pros

  • Includes 4 rechargeable AAAA Ni-MH batteries plus a dual USB charger, so you are not buying the charger separately.
  • Ni-MH rechargeable format (1.2V, 450mAh) with a stated “no memory effect” claim, which suits frequent top-ups.
  • Compact charger with LED indicator(s) and Type-C input (5V up to 2A) that can be used for small, routine recharging.
  • Buyer feedback commonly highlights getting pens and other small devices working again, plus practical day-to-day convenience.

Cons

  • Best fit is devices that specifically use AAAA rechargeable batteries, not general battery swapping for other sizes.
  • Charger output is limited to Ni-MH compatible cells, so it will not be useful for other battery chemistries.
  • Review evidence is limited in detail beyond basic performance impressions, so long-term capacity comparisons are hard to verify.

What buyers think

Reviewed productBuy on Amazon

Buyer-review evidence for this bundle is relatively consistent in its practical focus. Many comments center on convenience, especially the “batteries plus charger” idea, and on restoring functionality for small rechargeable devices. Several buyers specifically mention getting a stylus working again, and others describe the batteries as small but effective and report good battery longevity after setup. There is also recurring positive sentiment about the charger being handy for keeping batteries ready, but the overall review detail is not deep enough to conclusively compare charging speed or real-world runtime versus other AAAA Ni-MH options.

Who this is for

  • Stylus and small device owners who need AAAA rechargeable Ni-MH batteries and want an included charger.
  • People tired of repeated disposable battery purchases and who prefer routine recharge cycles for frequently used devices.
  • Travel and home users who value a compact Type-C charger for keeping a spare set topped up.

Key specs and compatibility to check

Before buying, confirm your device takes AAAA rechargeable Ni-MH batteries. This bundle includes 4x AAAA batteries rated at 1.2V with 450mAh capacity. The charger is designed for Ni-MH compatibility and uses Type-C input (5V, up to 2A), with dual output for 1.48V at 250mA x2.

The set also lists compatibility with several other common battery sizes (A, AA, AAA, AAAA, N, and C). Still, because your included pack is AAAA, the most reliable way to avoid disappointment is to match your device’s battery size exactly and confirm Ni-MH rechargeable support.

Pros and cons in plain English

Why buyers like it

  • Less hassle: you get batteries and a charger in one bundle.
  • Practical form factor: AAAA rechargeable batteries are made for small devices, so the “small but powerful” theme shows up in feedback.
  • Device recovery: buyers commonly describe getting pens or similar gadgets back into working order.

What to watch out for

  • Size matters: if your device uses a different size (AA, AAA, etc.), this bundle will not be a direct swap.
  • Chemistry matters: the charger is intended for Ni-MH rechargeables, so it will not suit other battery chemistries.
  • Performance proof is limited: detailed charging-time or long-term runtime comparisons are not well established in the available review snippets.

Alternatives by use case

  • If your priority is the charger: consider whether you already own a compatible Ni-MH AAAA charger. A batteries-only or separate-charger approach could reduce redundancy.
  • If you need multiple sizes: look for a broader rechargeable kit that matches every battery size you use at home (AA/AAA/AAAA) instead of AAAA-only bundles.
  • If you rely on a single device: you may prefer an exact-match rechargeable pack for that device’s specific battery type to keep spares organized.

Verdict

The Batmax bundle is a sensible pick if you need AAAA Ni-MH rechargeable batteries and want a matching dual USB (Type-C) charger to keep them ready. It is especially appealing for small rechargeable setups like active stylus use, with buyer feedback focused on convenience and restoring functionality. Just be rigorous about battery size and Ni-MH compatibility before ordering.
