Tectra 2-Pack BP-511 BP-511A Battery and Charger for Canon EOS
Quick take
This two-battery pack plus dual charger is designed for Canon cameras that use BP-511/BP-511A batteries. With 1800mAh (7.4V) battery capacity and USB-C or micro-USB input, it’s built for convenient backup power, especially for travel or charging from a laptop, car charger, or power bank. The main caveat is limited review evidence for charging performance, including at least one report that batteries would not fully charge.
Pros and cons
Pros
- Bundle includes two replacement batteries (BP-511/BP-511A) plus a dual charger.
- Higher capacity claim of 1800mAh at 7.4V, aimed at longer shooting sessions.
- Dual-slot charging with independent slots, so you can charge two batteries at once.
- Flexible power input, charger supports USB-C or micro-USB (5V input).
Cons
- Buyer feedback includes at least one case where batteries were not reaching full charge.
- “Super fast” charge time is a claim, but real-world timing can vary by power source and battery condition.
What buyers think
Buyer-review evidence is mixed but slightly positive. Several reviewers describe the batteries and charger as working as expected, with one specifically mentioning the kit restoring a Canon camera that had stopped working. Others keep feedback brief (for example, “It works” or “Good deal”). There is one detailed negative note about batteries not fully charging to 100%, and it is unclear whether the issue came from the batteries, the charger, or the charging process. Overall, the available review sample suggests the kit is functional for many users, but charging performance reliability is not fully proven due to limited data.
What you get in the bundle
This is a two-part kit: two replacement batteries and a compact dual charger. The charger is designed to charge two batteries simultaneously using a 5V input connection. Each slot is described as independent, which can be useful if you only need one battery topped up.
Key specs that matter for Canon BP-511 users
- Battery capacity and voltage: 1800mAh, 7.4V (BP-511/BP-511A replacement type).
- Charger input: 5V input, with a current rating listed for the charger.
- Charge time claim: about 2.5 hours to fully charge (timing depends on power source and battery state).
- Charging inputs: micro-USB and USB-C.
- Protection: built-in protection features are listed to help manage overcharge, discharge, temperature, and overcurrent conditions.
Compatibility: which Canon cameras it targets
The kit is intended as a replacement for Canon BP-511/BP-511A batteries. It lists compatibility with multiple Canon EOS models and PowerShot/Pro series cameras that use the BP-511/BP-511A battery type, including models such as EOS 40D, 50D, 30D, 20D, 20Da, 10D, and 300D, plus several PowerShot Pro and G-series cameras. If your camera uses a different battery, this bundle will not fit.
How the dual charger fits real-world use
The biggest day-to-day advantage is having a charger that can handle two batteries at once, which reduces downtime if you shoot for longer periods. The USB-C and micro-USB input options also broaden where you can charge from, like a wall adapter, car charger, laptop, or power bank (as long as the adapter provides the needed 5V output and sufficient current).
Pros and cons for different types of buyers
Best for
- Canon shooters with older EOS cameras that use BP-511/BP-511A and want a convenient backup battery setup.
- Travelers who want USB-based charging options instead of relying on a dedicated wall outlet.
- People who prefer dual-slot charging to reduce between-shoot downtime.
Who should avoid it
- Buyers who require proven, consistent “full charge to 100%” behavior, since review evidence includes a charging-completion complaint.
- Anyone whose camera uses a different battery model (this kit is specifically for BP-511/BP-511A compatibility).

Verdict
The Tectra 2-Pack BP-511 BP-511A battery and charger bundle is a practical option for Canon users who need replacement batteries and a dual USB-capable charger. The feature set is straightforward, the battery capacity is clearly stated, and many buyers describe it as simply working. The main reason to pause is the limited but notable report of batteries not charging fully, so if charging completion consistency is critical for your workflow, consider testing carefully once you receive the kit or compare against alternatives with more robust charging feedback.
